This usually begins in the teens or early twenties and affects mostly males. And one eye is usually worse than the other eye. It is also oftentimes familial, so alert other family members to get their eyes checked. As the cornea thins and bulges, it becomes distorted and even droopy, creating blurred vision that is not very correctable with glasses. Contact lenses can kind of give the eye a new, smoother front that focuses light properly. Rigid gas permeable lenses are my first choice, and they usually can be prescribed successfully.

It's a disease in which the cornea (the outer surface of the eye in front of the pupil) becomes cone-shaped rather than spherical, and this results in extreme astigmatism. Glasses can't correct this vision problem, but hard contact lenses often can. Unfortunately, the distortion of the cornea makes it very difficult to fit contacts comfortably for a keratoconic my eye doctor described it as "trying to balance a saucer on the end of a football." Ultimately, the cornea may suffer scarring which results in vision loss that can't be corrected by contacts. At that point, the next step is to replace the damaged cornea with a new one through cornea transplant surgery. This is only necessary for about 10 percent of keratoconics, but I'm one of them. There's much more about that a bit further down this page... The purpose of this web site is to provide information and resources to those who have keratoconus, and particularly those who have had, or are considering, a cornea transplant.

Send Email Keratoconus (KC) is a non-inflammatory condition of the cornea in which there is progressive central thinning of the cornea changing it from dome-shaped to cone-shaped. Keratoconus comes from the Greek word meaning conical cornea. The cornea is the clear windshield of the eye and is responsible for refracting most of the light coming into the eye. Therefore, abnormalities of the cornea can greatly affect the way we see the world. Keratoconus is not a blinding disorder, but does result in increasing near-sightedness (things far away are out of focus) and irregular astigmatism (things look tilted) that can significantly distort your vision. It is almost always bilateral (affecting both eyes). It is a slowly progressive disorder, taking years to develop, and may halt at any stage from mild to severe. Keratoconus has been well described since the mid-nineteenth century, however, the underlying reason for its development remains obscure. Keratoconus is currently the topic of much research. Some cases of KC have a hereditary component and studies indicate that about 8% of patients have affected relatives. However, most cases appear to be sporadic. It has been suggested that there is less than a 1 in 10 chance of having a child with some degree of keratoconus if one of the parents have KC without a family history. The actual incidence of KC is uncertain, large studies estimate 50 to 230 per 100,000. It occurs in all ethnic groups and has a slight female preponderance.

AOA | Keratoconus keratoconus Eye Diseases, keratoconus is a vision disorder that occurs when thenormally round cornea (the front part of the eye) becomes thin and irregular http://www.aoanet.org/conditions/keratoconus.asp
Extractions: Keratoconus is a vision disorder that occurs when the normally round cornea (the front part of the eye) becomes thin and irregular (cone) shaped. This abnormal shape prevents the light entering the eye from being focused correctly on the retina and causes distortion of vision. In its earliest stages, keratoconus causes slight blurring and distortion of vision and increased sensitivity to glare and light. These symptoms usually appear in the late teens or late twenties. Keratoconus may progress for 10-20 years and then slow in its progression. Each eye may be affected differently. As keratoconus progresses, the cornea bulges more and vision may become more distorted. In a small number of cases, the cornea will swell and cause a sudden and significant decrease in vision. The swelling occurs when the strain of the cornea's protruding cone-like shape causes a tiny crack to develop. The swelling may last for weeks or months as the crack heals and is gradually replaced by scar tissue. If this sudden swelling does occur, your doctor can prescribe eyedrops for temporary relief, but there are no medicines that can prevent the disorder from progressing. Eyeglasses or soft contact lenses may be used to correct the mild nearsightedness and astigmatism that is caused by the early stages for keratoconus. As the disorder progresses and cornea continues to thin and change shape, rigid gas permeable contact lenses can be prescribed to correct vision adequately. In most cases, this is adequate. The contact lenses must be carefully fitted, and frequent checkups and lens changes may be needed to achieve and maintain good vision.

Extractions: Definition Keratoconus, meaning "cone shaped," describes a condition in which the cornea (the clear front window of the eye) becomes thin and protrudes. This abnormal shape can cause serious distortion of visual images. The cause of keratoconus is unknown. It usually appears in a patient during their late teens or early twenties. The disease slowly progresses for 10 to 20 years as the cornea steepens and scars. Although both eyes may be affected, one eye is usually worse than the other. Vigorous eye rubbing can add to the disease process, therefore patients with keratoconus are advised to avoid rubbing their eyes. Symptoms Frequent changing of glasses or contact lens prescriptions Blurring and distortion of vision Glare Light sensitivity and irritation Scarring of the cornea The symptoms described above may not necessarily mean that you have keratoconus. However, if you experience one or more of these symptoms, contact your eye doctor for a complete exam. Treatment Although there are no medicines known which will prevent progression of the disease, mild cases of keratoconus can be successfully treated with glasses or specially designed contact lenses. When vision is no longer satisfactory with glasses or contact lenses, a

The word keratoconus is formed by the joining of two Greek words - kerato meaning cornea and konos , meaning cone. Keratoconus, or "conical cornea" means that the natural curvature of the normal cornea has changed to a cone-like bulge due to a thinning of the cornea. Scarring of the cornea often occurs. This affects vision, which may be blurred or distorted, or may produce a ripple effect. As the disease progresses the affected eyes become increasingly nearsighted (myopic). In its most advanced form functional vision can be destroyed. "It's like Col. Mustard in the library with a wrench," said Discovery Fund scientist Donald Brown, Ph.D. "Much like the ever-popular board game, our efforts in keratoconus research are focused towards understanding what is responsible for this disorder and how it achieves the corneal thinning and distortion." Keratoconus is an eye condition in which the normally round dome-shaped cornea progressively thins causing a cone-like bulge to develop. This results in significant visual impairment. The cornea is the clear window of the eye and is responsible for focusing most of the light coming into the eye. If it is distorted, then the image people see is distorted and out of focus. Although the cornea appears to be one clear membrane, it is actually composed of three distinct layers of tissue, each with its own function.

Extractions: Overview Keratoconus is a degenerative disease of the cornea that causes it to gradually thin and bulge into a cone-like shape. This shape prevents light from focusing precisely on the macula . As the disease progresses, the cone becomes more pronounced, causing vision to become blurred and distorted. Because of the cornea's irregular shape, patients with keratoconus are usually very nearsighted and have a high degree of astigmatism that is not correctable with glasses. Keratoconus is sometimes an inherited problem that usually occurs in both eyes. Illustration by Mark Erickson

Extractions: The cause of keratoconus remains unknown, although recent research seems to indicate that it may be genetic in origin. Certainly, some cases of keratoconus have a hereditary component and studies indicate that about 8% of patients have affected relatives. If there is no evidence of keratoconus in successive generations of a family, there is less than a 1 in 10 chance of the children of a person with keratoconus also having the condition. Excessive eye rubbing has also been implicated as a causative factor. How common is keratoconus?

Dry Eyes Keratoconus This is a progressive condition that causes the cornea to become thinner and eventually bulge forward in a cone-like shape. The result is increasingly distorted vision that cannot be corrected with eyeglasses or soft contact lenses. There are a variety of semi-rigid oxygen permeable lens designs that fit different types of keratoconus, and all of them do an excellent job of providing clear vision by negating or compensating for the distortion of the cornea. Sometimes, we will fit a combination of semi-rigid and soft contact lenses, a method called "piggy-back lenses". Unfortunately, in many cases, the ultimate progression of this condition results in corneal scarring, and eventually a corneal transplant is the only treatment.

Cataract Keratoconus is a corneal disease with causes thinning and protrusion of the front surface of the eye (cornea). In advanced stages it appears to be a "cone-shaped" cornea. Keratoconus typically starts early in life and slowly progresses with age. Patients with keratoconus typically are unaware of the condition until they no longer see well with a simple pair of glasses. It can easily be detected by your ophthalmologist using a special picture test known as computerized corneal topography. Although it has never been proven, there is strong evidence that habitual eye rubbing may have something to do with the progression of keratoconus. Most experts agree that genetics play a large part in determining who will be affected. The prognosis for a patient with keratoconus is good. It typically does not lead to permanent blindness and in most cases rigid gas permeable contact lenses (RGPs) can correct the vision. Seldom does a patient need a corneal transplant to correct the condition. If this is the case, the transplant is successful in correcting the vision in 90% of cases.
