Keratoconus
Keratoconus is a medical condition that results in gradual changes in vision and in shape of the eye. Most often beginning in adolescence, this degenerative illness occurs slowly and may not at first be diagnosed. Diagnosis is important, however, since over time mere corrective measures like using contact lenses may not do enough to correct vision, some people with Keratoconus will require Corneal Transplant.
Little is known about the causes of Keratoconus. Some people, like those with Down syndrome are at an increased risk for this condition. Yet others may have no other medical conditions and still get it.
What occurs with Keratoconus is that the cornea begins to stretch and get thinner, and this results in the eye having a slight protrusion in front that is shaped like a cone. The change in the cornea and the shape of the eye results in differences in the way the eye perceives light, and vision becomes blurry, resulting in astigmatism. Also distances become harder to see and nearsightedness or myopia is usually developed.
When diagnosed in the early stages, Keratoconus is usually treated with contact lenses of varying types. Rigid lenses may be preferred because they can help flatten out eye irregularities, but these may be uncomfortable to wear for some. There are some combination between rigid/soft lenses that prove a better solution. For some people, though, the cornea may become too damaged and vision may be impaired even with the use of lenses. In these cases, corneal transplant may be considered to replace the thinned and damaged corneas. About 8-10% of all corneal transplants are to correct the damage caused by this condition.
