Keratoconus is a slow, progressive eye disease in which the normally round, dome shaped cornea (the clear outer front portion of the eye) thins and begins to bulge into a cone-like shape.
In Keratoconus, the cornea is weaker than normal, and slowly bulges forward, to form the cone.
This causes distortion of light when it enters the eye. A defocussed image is formed on the photographic film of the eye.
