Keratoconus

What are the causes?

The cornea is the major focussing surface of the eye. In Keratoconus, the cornea becomes stretched and thin near its centre, and the thinned part of the cornea bulges making the vision more short-sighted and irregular. As a result the vision is distorted. The stretching of the cornea tends to progress but the rate varies. Sometimes one eye may be badly affected while the other eye may show very little sign of the condition.
