Keratoconus is a condition in which the normally round and dome-shaped cornea becomes thin and begins to bulge. This results in a cone-shaped cornea, with a point similar to the end of a football.
Keratoconus generally affects both eyes, although symptoms can vary between eyes. Common symptoms of keratoconus include:
Keratoconus is a slowly progressing condition. The symptoms above will get more severe as time goes on. Sometimes keratoconus will develop quickly, causing corneal scarring which can blur vision even more.
Keratoconus has no cure, but there are things that can be done to help vision. In the early stages of keratoconus, vision can be corrected using eyeglasses. Later, contacts may be used to help light reflect properly onto the cornea. Once good vision is no longer possible with contacts, a corneal transplant is recommended.
