What is keratoconus?

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 the early stages of this condition eyeglasses and soft contact lenses can be used to correct the prescription which generally contains astigmatism.  As the condition advances and the cornea thins more, the “cone” is more protruded and rigid contact lenses are the best option.  In a few cases, corneal transplants are necessary but contact lenses and/or glasses are still necessary.
