Center of vision blurry: The request could not be satisfied
10 warning signs of age-related eye problems
By Marilyn Haddrill and Gary Heiting, OD
Being aware of warning signs of vision problems as you age can help you take appropriate steps to protect your eyesight. Certain eye problems — such as with a detached retina or certain types of glaucoma — require prompt attention by an eye doctor to avoid or minimize permanent vision loss.
10 signs and symptoms of eye problems
The following signs and symptoms can indicate a medical emergency or an urgent condition that could cause significant vision loss over time. In most cases, you should see your eye doctor as soon as possible if you experience:
1. A sudden onset of many spots and floaters in your field of vision
Usually, eye floaters are due to a benign, age-related condition called vitreous detachment. This occurs when the eye’s gel-like interior liquefies and separates from the retina, the light-sensitive inner lining of the back of the eye.
But a sudden onset of spots and floaters also can be caused by a serious, sight-threatening tear or detachment of the retina. If you suddenly see a shower of spots and floaters, see an eye doctor immediately.
2. A sensation that a dark curtain has settled across your field of view
This could be caused by a retinal detachment, which occurs when the retina separates from the underlying layer of nourishing blood vessels (choroid). If the retina is not reattached within hours, vision loss can be permanent.
3. Sudden eye pain, redness, nausea and vomiting
These symptoms can signal a sudden (acute) attack of narrow-angle glaucoma, which can permanently damage the eye’s optic nerve. Immediate treatment is required to prevent permanent vision loss.
Blurry vision, ghost images and nighttime halos around lights all can be warning signs of eye problems.
A simulation of peripheral vision loss, also known as tunnel vision.
Double vision, double images or “ghost” images
Double vision can be caused by many eye conditions. In some cases, double vision also can signal an underlying health emergency such as a stroke. If you have a sudden onset of double vision, see an eye doctor immediately.
5. Sudden blind spot in one eye
If you are over 60, your chance of developing a macular hole in the most sensitive part of the retina. Because macular holes can worsen and cause permanent loss of vision, it’s important to see an eye doctor immediately if you notice a gray area or blind spot when viewing objects with one eye.
6. A narrowing of your field of view
A reduction of your ability to see objects off to the sides could be a sign of glaucoma. Without intervention, peripheral vision loss could continue to worsen, leading to tunnel vision or even blindness.
7. A gray, blurry or distorted spot in the center of your visual field
These symptoms may be caused by macular degeneration (AMD), a leading cause of blindness among older Americans. In the past, there was no effective treatment for macular degeneration. But today, new medical treatments sometimes can halt or limit AMD-related vision loss.
8. Poor night vision, halos around lights or less vivid color vision
These vision changes may be due to cataracts. Cataracts tend to worsen gradually over time and are not a medical emergency. Nevertheless, as your eye’s natural lens continues to cloud with aging, your vision will continue to deteriorate unless you have cataract surgery that replaces your cloudy lens with a custom intraocular lens (IOL).
If you wait too long for cataract surgery, you increase your chance of complications such as glaucoma. Also, if cataract surgery is postponed too long, the cloudy lens can harden and become more difficult to remove.

9. Blurred vision and gray areas in your visual field
If you have diabetes, these vision problems may be due to the onset of diabetic retinopathy. Regular eye exams are essential for diabetics, particularly if you are over age 60. By evaluating the condition of your retina, your eye doctor can provide valuable information to your general physician about the control and severity of your diabetes.
10. Red, “scratchy,” irritated eyes
These signs and symptoms are most commonly due to dry eye syndrome. Dry eyes usually are more of a nuisance than a sight-threatening condition. But symptoms can be severe, particularly as you grow older and your body produces fewer tears or your tear chemistry changes. Consult your eye care practitioner for advice about remedies, which may include over-the-counter or prescription eye drops.
Preventing age-related eye problems
It’s much better to prevent age-related eye problems than to try to minimize their impact on your vision after they have begun.
You can reduce your risk of developing serious eye problems later in life by maintaining a healthy lifestyle and having routine eye exams. Eye vitamins and good nutrition also may reduce your risk of certain eye problems. [Read more about tips for preventing vision loss.]

BLUR IN CENTER OF VISION A SIGN OF AGE
Q-I`m 58 years old and always have had good eyesight. I`ve never had to wear glasses, but lately I`ve been having a weird problem with my vision. The very center of my field of vision is blurry, while everything else is in focus. What could cause this? Am I going blind? Is there any treatment for what I have?
A-What you have described sounds like macular degeneration. The macula is the part of the eye that is responsible for sight in the center of the field of vision. Peripheral or side vision is usually not affected. Macular degeneration is caused by damage or the breakdown of the macula. In about 70 percent of cases, the degeneration is caused by aging. As patients get older, the tissues of the macula thin or break down.
Another 10 percent of cases are caused by a leak or break in the blood vessels that nourish the back of the eye. When this happens, scar tissue can form, and often new, abnormal blood vessels grow in the scar tissue. Central vision may become severely distorted and blurred.
More rare forms of the condition are inherited, or caused by injury, infection or inflammation. There is no cure for the most common age-related form of this problem, and judging from your age, this is probably what you have.
You can be reassured, however, that you will not go blind, since this problem affects only the center of vision. There are many low vision optical aids that can help you, including spectacles, special hand or stand magnifying devices and closed circuit television.
The most important thing to remember is that in the majority of cases these aids can help the patient lead a relatively normal life, but you must see an ophthalmologist immediately.
A doctor specializing in eye care can make a positive diagnosis and suggest which treatment could best solve this problem. Laser treatment, for example, might be used to stop a slow leak of blood from capillaries.
Across my desk: After a heart attack, many individuals live in a world of self-imposed fear, where they believe death may be just around the corner. Those are the sentiments expressed by Dr. Paul Thompson, medical director of the Miriam Hospital-Brown University cardiac rehabilitation program, in a recent issue of Medical Tribune. The negative experience of a serious attack puts the patient on the alert. Each little feeling or sign creates anxiety, turning the patient into a neurotic.
Thompson advocates that patients regain control of their lives, become involved in exercise programs that not only help their cardiovascular systems, but return an element of self-confidence to the patient. The depression that can follow a heart attack also may be reduced when the physician displays an attitude that indicates that all is going well. Since most patients do recover, Thompson said he prefers not to scare 999 patients to save one.

Why is my vision blurry? Here are 6 possible reasons
According to most sources, blurry, unclear vision is the most common eyesight problem in children and adults. Sudden changes in eye sight can be alarming. Luckily, it’s usually nothing to worry about. Though, that isn’t to say that it can’t cause some concern. In this blog post we talk about the major causes of blurry vision. If you or someone you love is worried about their blurred vision, hopefully this can provide some helpful answers!
1. You might need glasses, or you might need a new prescription.
Sometimes the curve of the eye disturbs the angle at which light hits the retina, and this produces a blurry picture. We call this issue myopia, or nearsightedness. It can also be a sign of hyperopia, or farsightedness. Astigmatisms are another common refractive error. These conditions can be remedied with corrective glasses or contacts, or an update to your prescription. For some people, LASIK surgery also proves to be a good solution.
2. You might have conjunctivitis.
It sounds scary, but conjunctivitis is nothing too serious. Most people refer to this virus as pink eye. Symptoms include sudden burning, itching, and eye discharge. It is a condition that can be caused by allergies, or infection from bacteria or a virus. Similar to a sore throat or a cold, this virus is very contagious and can spread very quickly through crowded areas. Depending on the cause of pink eye, it can go away within a week or two all on its own, but if symptoms are severe enough, it might be wise to come in and let a doctor take a look. They may provide a medical solution for your eye health. Eye drops can reduce itchiness, and maintaining clean bedding and not touching your eyes will prevent further infection or illness.
3. You might have presbyopia.
If you’re over the age of 40 and you’re finding it harder and harder to read, you probably have presbyopia. Presbyopia is a condition that has to do with the refraction of light onto the retina, and it frequently occurs with age. If, all of the sudden, you find yourself holding your phone or your reading material far away from your eyes so that you can see it better, it may be a sign that you have successfully made it to this stage of life. Reading glasses can help! Reading glasses will reduce strain on your eyes and correct this potentially annoying situation.
4. You might have slept with your contacts in.
Contact lenses move across the eye with every blink, creating tiny scratches. Normally the body has no issue immediately repairing these microscratches, but with your eyes’ rapid movement while dreaming and the extended period of the contacts being in, the damage can be enough to allow microorganisms in and get into the scratches, causing infection.
5. You might be developing cataracts.
Like presbyopia, cataracts are one of the eye problems that occur with aging. Cataracts happen when the lens inside of the eye loses its clarity and causes clouded light to enter the eye, which can result in blurred vision. While some cataracts stay small and don’t cause any issues, most grow and can inhibit clear vision. A doctor can usually treat cataracts with corrective surgery.
6. Accommodative problems.
Like a camera taking a picture, our eyes have to change focus for the distance we are looking at. Sometimes that focusing system malfunctions and causes one to have blurry vision that may come and go, especially after extended time viewing things up close. At times, glasses can help correct these problems, but often Vision Therapy is needed to help the eyes learn to focus together in a more coordinated way.
If you’re worried about blurry vision, hopefully one of these frequent causes has given you some guidance about what to do next.

What are the symptoms of blurry vision?
Blurry vision can cause a variety of symptoms in one or both of your eyes. For some patients, their entire line of sight can be affected, while others may only have partial areas of vision that are blurry.
In addition to having blurred vision, you might feel as though your vision is dim or cloudy.
What causes blurry vision?
Blurry vision is a common symptom of vision problems, such as nearsightedness, farsightedness, or astigmatism. Additional causes of blurry vision might include:
- Age-related macular degeneration
- Infectious retinitis
- Abrasions to the cornea or corneal scarring
- Injury or trauma to the eye
Other health conditions can cause blurry vision as well, such as migraines, stroke, or fluctuations in blood sugar due to diabetes.
How is blurry vision diagnosed?
First, Dr. Amin or Dr. Hardy will perform a comprehensive eye exam. During your appointment, they will discuss your symptoms, review any medications you may be taking, and talk about your overall health and work environment. They’ll also look at any vision issues you may have had in the past and any that may be in your family history.
To evaluate your eye function, Dr. Amin or Dr. Hardy will conduct tests to measure your eye muscle capabilities, peripheral and color vision, responsiveness to light, and depth perception. They’ll also look to see if your eyes are correctly focusing and working together.
They’ll also check your overall eye health. During this portion of your appointment, Dr. Amin or Dr. Hardy will visually examine your eyes, eyelids, and inside of your eyes using magnification and a bright light. They might also perform tonometry testing to examine the pressure in your eyes.
Based on these tests, your doctor can determine the best strategy for correcting your blurred vision.
How is blurry vision treated?
Dr. Amin or Dr. Hardy will provide a treatment plan to correct your blurry vision based on the cause of your condition. These approaches might include:\
- Vision therapy
- Contacts or prescription glasses
- Orthokeratology, or Ortho-K
- Laser surgery
They might also suggest medications to control any underlying health conditions.

What to do if you have a sudden loss of vision
By John L. Henahan,
Special to The Citizen
A sudden loss of vision in one or both eyes is one of the scariest experiences a person can have, says Dr. John Henahan of Spectrum Eyecare in Peachtree City.
When you experience a sudden change in vision, it’s important to remain calm and ask yourself some simple questions to help your doctor uncover a cause, says Dr. Henahan.
Here is what to pay attention to:
• How long ago did the problem first arise? Hours? Days? Months?
• Has my vision changed in one eye or both eyes? Cover one eye at a time and look around to decide.
• How long did the vision loss last? A few seconds, several minutes or is it persisting?
• Is the vision loss a blur, a dark spot, or bright shimmering effect?
• Does the area of vision loss stay in the same area of your vision or does it move around independently of your eye movements?
• Did it come on suddenly or has it been gradually worsening?
• Is the eye painful? Is it red? Are you more sensitive to light than normal?
All of these questions can help the nurses and doctor pinpoint the most likely cause of your vision loss, to perform a focused exam to confirm the cause and to quickly begin treatments to help save your vision.
Causes of sudden blurred vision that doesn’t threaten your vision
A common visual disturbance that does not indicate a threat to the vision is a migraine headache.
Migraines can begin at any age. Often they have no visual symptoms, but in a classic migraine, the headache is preceded by a visual disturbance, often called an “aura.” The classic aura is a bright, shimmering “C” shaped blur that starts in the center of vision (in BOTH eyes). It gradually moves from the center of vision off to the side where it eventually dissipates (usually after about 20 minutes). When followed by a headache, it is known as a classic migraine. When no headache occurs, it is called a visual or ophthalmic migraine.
Dry eye can cause sudden blurred vision. Typically, the complaint is that the vision goes out of focus when reading or on the computer. Closing the eyes or blinking several times seems to resolve the issue. The blur usually lasts less than one minute and is described as having a foggy quality.
Vision-threatening causes of sudden blurred loss
There are many possible causes of sudden sight-threatening vision loss.The most common causes are described below:
A sudden onset of dark floating spots in front of one eye, especially when accompanied by flashes of bright light and blurred vision can indicate a sight threatening emergency called retinal detachment. When caught early, this serious condition is highly treatable and vision is likely to be saved. If treatment is delayed then irreversible vision loss can occur in the affected eye.
Retinal bleeding (from macular degeneration or diabetes)
The retina is a highly organized, amazingly precise structure. When that organization is disrupted, the vision becomes distorted, blurry or both. In diabetes and wet macular degeneration, blood leaks out of blood vessels and into the retina causing it to swell. This bleeding disrupts the organization of the retina and causes vision loss that is perceived as a dark blurred spot or distorted vision. Generally, even if the blood dissipates the retina never regains totally normal function because the precise organization is permanently affected.
If you are diabetic, it is essential to control your blood sugar and to have a complete dilated retinal eye exam at least once per year. Early treatment is key to retaining good vision if retinal bleeding develops in your retina. Any sudden change in vision in one eye is considered a serious issue that warrants an eye check within several days.
In macular degeneration (AMD), the problem is usually a deterioration of the retina that can sometimes result in bleeding in the retina. If this bleeding occurs you can experience a sudden loss of central vision that feels like a dark spot in the center of vision. New treatments have been developed for this “wet AMD” that have greatly improved outcomes, but still usually result in some residual vision loss.
Normally, glaucoma is notable for the absence of symptoms and the decades it takes to cause blindness. A less common form of glaucoma called sudden angle closure glaucoma can cause permanent loss of vision in just a few days. In sudden angle closure, the eye pressure skyrockets to more than three times its normal amount. As the pressure in the eye builds, it destroys the optic nerve. The symptoms include an extremely painful red eye with blurred vision. The pain can be so intense that vomiting often occurs.
If you suspect that you are having sudden angle closure glaucoma, it is imperative that you seek care immediately. Various eye drops and oral medications can quickly stop the attack, allowing the eye pressure to return to its normal level. A simple laser treatment can prevent future attacks after the initial crisis has subsided.
The iris is the colored part of the eye that allows the pupil to expand and contract depending upon how bright the environment is. A large number of medical problems can result in inflammation developing in the iris. It can occur in one or both eyes. When iritis develops, the eye feels sore with a deep ache, light sensitivity and blurred vision. If untreated, iritis can lead to permanent damage to the eye, as well as causing cataracts and a type of glaucoma that is very difficult to control. Treatment usually consists of drops. A complete physical and blood tests may be needed to determine the underlying cause of the iritis. Treatment of any systemic health problems can reduce the chance of recurrence.
If you experience a sudden loss of vision that persists for more than 30 minutes, contact your eye doctor for an appointment.

Blurred Vision, Blurry Eyesight: Symptoms, Causes, Treatments
There are many different eye problems and conditions that can cause blurred vision.
To understand how refractive errors cause blurred vision, it first helps to understand how the eye works. Refractive errors that cause blurred vision include:
Long sightedness: causes blurred vision when viewing objects close up, such as when reading a book or using a computer.
Short sightedness: causes blurred vision when viewing objects at a distance, such as when watching television or driving.
Astigmatism: causes blurred vision when viewing objects at any distance, from reading and computer use, to driving and watching television.
Cataracts: Cataracts are a clouding of the lens in your eye. At first, any blurred eyesight may be almost imperceptible. However, cataracts can eventually result in severe blurred vision that has a major impact on your independence.
If you have had a cataract removed and your blurry vision re-occurs, posterior capsule opacity – also known as a ‘secondary cataract’ – may be the cause. This is easy to treat.
Diabetic retinopathy: Diabetic retinopathy is a condition associated with diabetes. High blood sugar levels cause damage to the retina (the focusing surface at the back of the eye). The final stage of diabetic retinopathy, known as macular oedema, can cause blurred vision.
Epiretinal membrane: An epiretinal membrane is a thin, fibrous layer that forms over the retina (the focusing surface at the back of the eye). It acts like a film that partially blocks the light entering your eye, which results in blurred vision.
Keratoconus: Keratoconus is an eye disease that results in a conically shaped cornea (the clear front ‘window’ of your eye). Because the cornea does much of the eye’s focusing, the irregular shape can cause blurred vision.
Macular degeneration and macular holes: The macula is the central part of the retina at the back of your eye. It allows you to see detail, colour, and things directly in front of you. Macular degeneration and macular holes damage the macula, causing central vision to become blurred.
Retinal detachment: A detached retina is a serious medical emergency that can cause sudden blurred vision. It may also cause a number of other symptoms, such as flashes and floaters, and sudden blindness.
Retinal vein occlusion: If the blood vessels that feed the retina (the focusing surface at the back of the eye) become blocked, it is known as a retinal vein occlusion. This can cause sudden blurred vision, and also sudden blindness.
Pterygium: A pterygium is a benign growth that occurs on the surface of the eye. Sometimes, a pterygium can grow onto the cornea. If this occurs, it can alter the shape of the cornea, causing blurred vision.
Vitreous haemorrhage: If blood leaks into the vitreous ‘gel’ that fills your eye, it can block the light that enters your eye, causing blurred vision. Vitreous haemorrhage can be caused by trauma or injury, or it may be a result of an eye condition, such as diabetic retinopathy.
Eye infection, inflammation or injury: Many people suffer blurry vision as a result of an eye infection or injury. Eyelid and eyelash problems can sometimes cause blurred vision, as can the common eye infection conjunctivitis.
Treatment will depend entirely on what’s causing the blurring. Refractive errors – such as long sightedness, short sightednessand astigmatism – can now be permanently corrected in most people, thanks to the development of LASIK, an advanced laser eye surgery procedure available in New Zealand through us at Eye Institute.
If you suffer from blurred vision, the best thing to do is contact us. Our specialists can give you a full diagnosis and recommend the best treatment for you.
Cloudy Vision in One Eye: Causes and Treatment
Having cloudy vision makes it seem as though you’re always looking through a fog or haze. It can occur in one or both eyes, and be the sign of a minor issue or a more serious condition.

What Is Cloudy Vision?
Though they may sound similar, there is a difference between “cloudy” and “blurry” vision.
- Cloudy vision feels like you’re looking at everything through a fog or a haze.
- Blurry vision means that what you’re seeing is out of focus.
Here, we’re going to review cloudy vision, which can affect either one or both eyes. In addition to feeling like you’re looking through a dirty or foggy window, cloudy vision can also include:
- Blurry vision
- Seeing faded colors or halos around lights
- Difficulty seeing at night
Cloudy vision can be temporary—resulting from a minor issue like a floater—or may be permanent unless treated with surgery, like cataracts.
There are a variety of different conditions that could cause cloudy vision, ranging from minor to serious, and common to rare. Here’s what to know about these conditions, including their symptoms other than cloudy vision.
Eye floaters are one of the most common causes of both cloudy and blurry vision. These can look like squiggly lines, blobs, or other shapes moving over your vision.
In most cases, floaters are nothing to worry about and will go away on their own. But if many appear suddenly, or they result in either central peripheral vision loss, it’s time to see a doctor.
Injury, Infection, or Inflammation
Sometimes, cloudy vision may result from an:
Seek medical treatment for the underlying condition to help get rid of the cloudy vision.
In cases of mild cataracts, a person may not initially have symptoms. But eventually, the most recognizable signs of the condition are cloudy vision, and a person’s lens becoming visibly cloudy to others. This is the result of the proteins in the eye breaking down and clumping together. The clumps appear as cloudy spots on a person’s lens, known as cataracts.
Other symptoms of cataracts include:
- Colors look faded
- Poor vision at night
- Lamps, sunlight, or headlights seem too bright
- Halos appear around lights
- Double vision
- Frequently having to change the prescription for your glasses
Fuchs’ dystrophy is a disease of the cornea that occurs when cells in the inner corneal layer die off. This results in fluid building up on the cornea, and a person’s vision becoming cloudy or blurry.
There are two stages of Fuchs’ dystrophy. In the first stage, many people don’t notice any symptoms—and if they do, it’s cloudy vision when they first wake up in the morning.
Symptoms of the second stage don’t go away over the course of the day and can include:
- Sandy or gritty feeling in your eyes
- Being extra sensitive to bright light
- Eye problems get worse in humid areas
- Very blurry or hazy vision from scarring at the center of the cornea
Age-related macular degeneration occurs when the macula at the back of the eye starts to deteriorate. Symptoms of the condition may include:
- Cloudy vision
- Blurry vision
- Blank or dark spots in your field of vision
- The appearance of waves or curves in straight lines
Diabetic retinopathy is an eye condition that can cause cloudy vision or vision loss in people who have diabetes.
While the early stages of diabetic retinopathy typically doesn’t come with noticeable symptoms, later stages may include changes in vision, or seeing dark, floating spots or streaks that look like cobwebs.
When to See a Doctor
Any time there are any issues with your vision—including cloudy vision in one or both eyes—it’s a good idea to see a doctor to make sure there’s nothing seriously wrong with your eye or eyes.
In addition to cloudy vision in one or both eyes, get a complete eye exam with an optometrist or ophthalmologist if you have:
- Trouble seeing objects in your peripheral vision
- Difficulty seeing at night or when reading
- A gradual loss of the sharpness of your vision
- Difficulty telling colors apart
- Blurred vision when trying to view objects near or far
- Diabetes or a family history of diabetes
- Eye itching or discharge
- Vision changes that seem related to medication. (Although, don’t stop or change a medicine without talking to your doctor
When Is Sudden Cloudy Vision in One Eye a Medical Emergency?
In some cases, sudden cloudy vision in one or both eyes could be the sign of something serious, and requires emergency medical treatment. These include:
- Experiencing partial or complete blindness in one or both eyes, even if it is only temporary
- Experiencing double vision, even if it is temporary
- Having a sensation of a shade being pulled over your eyes or a curtain being drawn from the side, above, or below
- Experiencing blind spots, halos around lights, or areas of distorted vision appear suddenly
- Having sudden blurred vision with eye pain, particularly if the eye is also red. A red, painful eye with blurred vision is a medical emergency
The treatments for cloudy vision in one or both eyes depends on its root cause. For example
- For cataracts: Surgery is the only option.
- For Fuchs’ dystrophy: There is no cure but depending on the severity of the case, it can be treated using eye drops, or a corneal transplant.
- For macular degeneration: There is no cure, though it’s commonly treated through certain nutritional supplements, antivascular endothelial growth factor, and photodynamic therapy.
- For diabetic retinopathy: This can be treated with eye injections, laser surgery, or other types of eye surgery.
A Word From Verywell
Cloudy vision is annoying, but it could also be an indication of something more serious happening with your eyes. Take note of when the cloudy vision started and how long it lasts, and be sure to provide your doctor with this information. And if the cloudy vision is accompanied by any of the symptoms listed above, make sure you get the medical attention you need, as quickly as possible.

Vision of the affected eye
Cataract is a clouding of the lens of the eye, which is located behind the pupil. Through this lens, light rays enter the retina, forming images there. Therefore, when the lens loses its transparency and prevents free passage of light to the retina, the patient experiences a progressive loss of vision.
The most common cataract symptoms are:
- Blurred vision, glare, poor night vision
- Difficulty driving at night, photophobia, glasses have to be changed often
For more information on this pathology, click on this link.
How to proceed?
- Cataracts cannot be prevented, but can be detected by ophthalmologic examination. It is recommended to consult an ophthalmologist, especially after 45 years, in order to detect the possible presence of cataracts, its type, size and location, and to determine whether it is worth doing the operation, and at what point.
Astigmatism is a refractive defect that provokes the projection of images on the retina in a distorted form, affecting vision near and far.
Astigmatism can manifest itself alone or in combination with myopia or hyperopia and is usually stable throughout life.
- Getting distorted images (most common symptom)
- Problems with changing distance / near vision.
- Difficulty seeing small details, both up close and at a distance.
- Headaches, eye pain or dizziness as a result of muscular effort when the eye tries to compensate for a defect by accommodating the lens (a natural lens of the eye whose elasticity allows focusing).This is especially true in cases of a combination of astigmatism and hyperopia.
For more information on this pathology, click on this link.
How to proceed?
- Astigmatism can be corrected with glasses or contact lenses.
- If the patient wants to do without optical correction, there are surgical treatments.
- Refractive surgery includes various methods, depending on the specifics of each diagnosis:
- Excimer laser: used in the treatment of the middle layers of the corneal tissue.
- Incisional technique (arcuate keratotomy): It consists in making incisions on the surface of the cornea and is used for high-grade astigmatism.
- Toric intraocular lenses: phakic (implanted between the cornea and the lens) and pseudophakic (replacing the lens). They are widely used to correct high degree of astigmatism.
- Simple. This refractive error is characterized by normal refraction of light rays on one of the meridians (i.e. emmetropia) and myopia or hyperopia on the other.
- Difficult . On the main meridians there is one type of refractive error (myopia or hyperopia), but of varying degrees.
- Mixed. Characterized by the presence of hyperopia on one main meridian and myopia on the other.
- Correct. This is direct astigmatism of the eye, in which the refractive power of the vertical main meridian is higher than the horizontal one; as well as reverse astigmatism, in which the refractive power of the horizontal meridian is higher.
- Invalid. This is astigmatism, in which the location of the main meridians is not perpendicular and / or within one meridian there are several variants of refractive errors.
- Congenital. Congenital astigmatism of the eye can be physiological (if it does not exceed ± 0.5-0.75 D) or pathological. Refractive errors can be associated with genetically determined factors or with the pathology of embryogenesis.Among the most common causes of congenital astigmatic anomaly are:
- congenital disorders of corneal sphericity,
- anomalies of the structure of the eyes (microphthalmos).
- Acquired . It is possible the formation of astigmatism against the background of ophthalmic diseases or eye injuries, which lead to a change in the normal spherical shape of the cornea. These types of pathology include:
- Complications of ophthalmic operations on the lens and cornea,
- subluxation of the lens,
- some types of cataracts, etc.d.
- up to ± 3 D – light,
- ± 3- + – 6 D – average,
- more than ± 6 D – high.
- Decreased visual acuity. This is the main symptom of astigmatism and is the result of an imbalance in the focus of the image on the retina. Due to the different refractive power of certain parts of the cornea (or lens), part of the image can be focused behind the retina, and part in front of it.As a result, the image is perceived as blurry. Its proportions may also be distorted.
- Asthenopia. This is a sensation of rapid eye fatigue, a feeling of dryness and burning sensation and other uncomfortable phenomena. Against the background of asthenopia, headaches often develop, mainly in the area of the brow and forehead.
- Optical correction. After the examination, the doctor selects lenses or glasses, a feature of which is a different refractive power along the two main meridians of the eye.Lenses for astigmatism also have a special design aimed at stabilizing the structure and preventing its rotation (otherwise, the movement of the lens on the eyeball will cause visual impairment and asthenopic complaints). In the Center for the Protection of Vision, there is a contact correction department, whose specialists select the best option for lenses or glasses for each patient.
- Laser vision correction. Modern equipment in the I. Medvedev ophthalmological clinic allows for accurate diagnostics of eye astigmatism and calculates the optimal area and depth of laser vision correction.This allows you to correct the refractive power of the cornea with pinpoint precision and achieve excellent, stable results.

90 017 90 000 Astigmatism of the eye: classification and treatment – Articles
Astigmatism is one of the refractive errors in which the refractive power of the transparent media of the eye is disturbed.As a result, the image on the retina is not focused correctly.
With astigmatism, the refractive power of the two main meridians of the eye, which are normally perpendicular to each other, is taken into account.
Types of Astigmatism:
By localization of refractive errors:
Time of Occurrence:
Degree of astigmatism of the eye:

Intraocular Phakic Lenses (IPL) – Irina Svyatoslavna Fedorova Eye Clinic – FIS Center
Studies of modern lens models show that IPL provide high vision and have a good safety profile.
Unpleasant sensations in the postoperative period occur less often than with LASIK, since the implantation of intraocular phakic lenses is much less traumatic for the cornea.
About 20% get sight even more than 100%. The rest have a visual acuity of 0.5-1.0, depending on the initial state of the eye. Of course, patient satisfaction is high.
Advantages of IFL
We already mentioned the main advantage at the beginning. When implanting intraocular phakic lenses, nothing needs to be removed, all eye tissues remain intact.This is a serious “plus” that neither LASIK nor an artificial lens can boast of. With LASIK, the laser vaporizes the middle layer of the cornea, and when the lens is replaced, its own is crushed by ultrasound and removed in parts from the eye. IPL implantation is the only corrective operation reversible – the lens can be explanted at any time.
IFL – “final” vision correction. You will no longer need to change lenses and put on / take off your glasses.
IFL copes where LASIK will not help.The main contraindications for laser vision correction are a thin cornea or very high myopia. The LASIK effect is based on thinning the cornea, so if the thickness of the cornea does not allow removing the required amount of tissue, no laser correction is out of the question. And for IPL, the thickness of the cornea does not matter.
With IPL, accommodation does not suffer – the natural focusing of the eye at different distances, since the own lens, which is responsible for this process, remains intact.At the age of 40-60, natural processes gradually begin, which makes it difficult to focus near vision. Difficult, but not impossible. If accommodation goes away with the replacement of the lens, it remains intact during IPF implantation.
Disadvantages of IFL
There is no such thing that treatment does not have “minuses” and / or contraindications, and IFL is no exception.
In rare cases, due to the anatomy of the eye, the lens is not positioned correctly. This can lead to increased intraocular pressure or cataracts.But! As we mentioned earlier, the lens can be removed or replaced. In addition, these problems were common in early versions of the IFL. For example, cataracts occurred in 9% of cases. Nowadays, lens design has stepped forward, and such complications occur only in 0.5% of cases.
There are also “little things” that go away by themselves within a couple of months after the operation. But it’s still worth mentioning them. IPL implantation is an operation, so at first it may seem that something has got into the eye and disturb the “light”.On average, it goes away in a month.
In addition, IFLs are more expensive than the same LASIK.
Is IFL Right For You
Who is an ideal candidate for intraocular phakic lens implantation?
If you are 21-45 years old, myopia does not progress, laser correction (LASIK or analogs) is contraindicated, and there is no desire to wear lenses or glasses, then IFL is a good option.
However, as with any surgical procedure, intraocular phakic lenses are not indicated for everyone.There are many subtleties that can only be seen after special examinations. Therefore, it will not be possible to remotely resolve the issue of IPL implantation. You will have to visit a vision correction specialist.
How does a laser work? | DoctorVisus.ru
To understand the essence of laser correction, let us briefly and schematically recall the anatomical physics of the eye. The optical system of the eye consists of two structures: the light-refracting part – the cornea and the lens and the light-receiving part – the retina, located at a certain (focal) distance.In order for the image to be sharp and clear, the retina must be in the focus of the optical power of the ball.
If the retina is in front of the focus, which happens with hyperopia or behind the focus with myopia, the image of objects will be blurry and indistinct. At the same time, from the moment of birth until the age of 18, the optics of the eye changes due to the physiological growth of the eyeball and under the influence of factors that often lead to the formation of certain refractive errors. Therefore, the patient of a refractive surgeon often becomes a person who has reached the age of 18, and with hyperopia – even from the age of 14.
Excimer laser vision correction is based on the program of “computer reprofiling” of the surface of the main optical lens of the human eye – the cornea. According to the individual correction program, the cold beam “smoothes” the cornea, eliminating all existing defects. At the same time, normal conditions are formed for optimal refraction of light and obtaining an undistorted image in the eye, as in people with good vision.
The process of “re-profiling” is not accompanied by a destructive increase in the temperature of the corneal tissues, and, as many mistakenly believe, no “burnout” occurs.Most importantly, excimer laser technologies make it possible to obtain such a “perfect new preset profile” of the cornea, which made it possible to correct almost all types and degrees of refractive errors with them.
Scientifically speaking, excimer lasers are high-precision systems that provide the necessary “photochemical ablation” (evaporation) of the corneal layers. If tissue is removed in the central area, the cornea becomes flatter, which corrects myopia. If you evaporate the peripheral part of the cornea, then its center will become more “steep”, which makes it possible to correct hyperopia.Dosed removal in different meridians of the cornea allows astigmatism to be corrected. Modern lasers used in refractive surgery reliably guarantee a high quality of the ablated surface.
Astigmatism – treatment in Odintsovo
Astigmatism is a very common optical defect of vision. And if you have been diagnosed with such a diagnosis, you should not be afraid of it. Astigmatism up to 0.5 diopters is considered physiological and it is not necessary to correct it with glasses.If, in the process of selecting glasses and correcting astigmatism, visual acuity significantly improves, it is recommended to correct even 0.25 diopters.
Astigmatism is a condition of the eye formed due to the cornea elongated into an irregular shape. Normally, it has a rounded shape, while the cornea of people with astigmatism is oblong. This provokes a light refraction error.
As a result, the image is blurred or distorted, which provokes eye strain and visual fatigue.
Astigmatism is often combined with other visual impairments – myopia and hyperopia.
Symptoms of astigmatism
The main signs of the presence of astigmatism are:
at the object
Causes of astigmatism
The main and most common cause of astigmatism is heredity. Adults with a significant degree of astigmatism can identify the problem, while children rarely attach importance to blurry vision and blurred objects. Therefore, it is very important to regularly diagnose vision and, in particular, astigmatism in children.
Other causes of astigmatism include eye injuries and diseases. Keratoconus often leads to a high degree of astigmatism.
Treatment of astigmatism
Astigmatism lends itself well to correction with glasses. Used for this purpose, cylindrical lenses correct irregular corneal optics and provide clear vision. Astigmatism can also be corrected with special toric contact lenses.
Orthokeratological treatment can also be used for astigmatism. The doctor prescribes hard contact lenses for night wear. They gradually change the shape of the cornea, and the patient sees well during the day.It is important to know that lenses do not improve vision forever: if you stop using them, the problem returns.
Some types of astigmatism are treated with a laser. The operation is carried out only according to the indications of the attending physician.

Treatment of astigmatism in Togliatti – Interregional Laser Center
Astigmatism is characterized as a different kind of refraction of light rays along the eye axes.It is characterized by an irregular curvature of the ocular cornea. In a healthy eye, the cornea is shaped like a soccer ball, but in an eye with astigmatism it will be more like a rugby ball. In this case, the shape of the cornea will be ellipsoidal. It is due to this that the eye differs not in one optical focus, but in two.
Astigmatism: blur, split, ghost effect
The cornea collects light in two places at once.This feature of the structure of the eye leads to the fact that a person sees everything not clear, but blurred. And this feature can not always be called a pathology. Physiological astigmatism is considered to be the norm. In this case, the difference between the vertical and horizontal meridians is no more than 1 diopter. A big difference is already evidence of pathology.
Such a feature of the structure of the eye, as astigmatism, is found in people of different age groups. His character can be both congenital and acquired.Inherited astigmatism is called congenital. The one obtained as a result of injuries of various nature and the interventions of surgeons that contributed to the development of scar formation is called acquired. Acquired astigmatism may also be caused by recent exposure to certain eye diseases, in particular Keratoconus . It also happens that people do not even know that they suffer from astigmatism. Rapid fatigue, a feeling of fullness, “sand” in the eyes are attributed to other factors.These symptoms are far from special, they are characteristic of other, various diseases and pathologies. With astigmatism, another visual impairment can be detected. Often it is accompanied by farsightedness or myopia.
A high degree of astigmatism is a serious and complex disease. At the same time, human vision is poor both at a great distance and at close range. Difficulties arise with determining the distance between objects. It is difficult for a person to determine what is in the distance and what is in the near distance.The contours of objects are distorted. The need to constantly wear glasses is due to the very low visual acuity. For a person suffering from this pathology, there are many restrictions on the load of vision, respectively, he is limited in actions that a healthy person can perform without problems. Therefore, it is imperative to deal with the treatment of astigmatism.
There is astigmatism not only with hyperopia and myopia, but also mixed. This is due to the distortion of one axis towards farsightedness, and the other – myopia.
Treatment of astigmatism should be done in a timely manner. The neglect of astigmatism can lead to the development of amblyopia. If this happens, then the correction of astigmatism will already be a pointless undertaking and will not give any results.
Treatment of astigmatism is carried out by wearing glasses, which can be purchased in Togliatti. Despite the fact that for a very large number of people who suffer from this pathology, wearing glasses is difficult to tolerate, for a huge number it is a panacea.
Purchasing glasses is a whole science. For astigmatics, optics are selected individually. You can’t just go out and buy the glasses you need right away. In Togliatti, they are made to order.
Correction of astigmatism is carried out with the help of toric lenses, but in order to wear them, you need to undergo special training from an ophthalmologist.
Laser correction is another option for getting rid of this ailment. With the help of a laser, the shape of the cornea is reshaped. This procedure is done with astigmatism of no more than 4 diopters.It is practically painless. Immediately after its completion, a person will notice a significant change in his vision. The vision becomes much sharper when this treatment is completed.
The postoperative period requires some restrictions. You should abandon any stress, both physical and visual. You should avoid going to saunas and baths, drinking alcohol and beware of all kinds of injuries. Visits to the ophthalmologist should be done regularly. Prevention of astigmatism is also mandatory.
Treatment of astigmatism can be performed at the Interregional Laser Vision Correction Center in Togliatti. An ophthalmologist with extensive work experience will carry out a complete diagnosis and prescribe the necessary procedures for the treatment of astigmatism. For a whole year after surgery, you will not have to pay for doctor’s examinations. This service is free of charge for patients.
Myopic Astigmatism | Podolsk center of vision
With myopic astigmatism, visual impairment occurs against the background of simultaneously occurring diseases – myopia and astigmatism.As a result, pathologies overlap and reinforce each other, which leads to a sharp deterioration in the vision of one or both eyes.
In case of illness, focusing on the retina is disturbed, when not a complete image is fixed on it, but only a part of it. The reason is the curvature of the cornea, when it acquires an irregular shape and gives a blurry picture of various objects.
Etiology of the disease
Types of myopic astigmatism
In ophthalmology, the following types of ailment are distinguished:
Based on the stages of the disease, three degrees of myopic astigmatism are distinguished:
In any form of myopic astigmatism, similar symptoms are observed. Patients complain of migraine attacks and fatigue even with minimal visual stress.The eyes water involuntarily, there is a pain in them and a feeling of the presence of a foreign body.
Regardless of the degree and complexity of the disease, there are complaints that visible objects become blurry, indistinct and poorly visible. They are presented in a distorted form, they can double or stretch. This forces the person to squint, pull back their eyelids and tilt their head, changing the angle of view. At first, a picture is perceived realistically only when the disease has just manifested itself and is in its initial form.
If at least one of the above symptoms is present, you should immediately contact an ophthalmologist and have your vision checked. Launched myopic astigmatism is fraught with complications, which is especially dangerous during pregnancy.
What methods are used to determine visual acuity and quality? For this, a comprehensive examination is prescribed:
The initial stage of the disease is treated by wearing lenses or corrective glasses, as well as special eye exercises.
