Keratoconus is an uncommon degenerative eye disorder in which the normally round, dome-like cornea (the clear front window of the eye) becomes thin and develops a cone-like bulge. Keratoconus literally means “cone-shaped cornea”.

Symptoms of Keratoconus include sensitivity to light and distortion of vision. If the condition affects both eyes it can, in time, influence a person’s ability to drive or read normally.


Although usually a progressive disease, recent data suggests that it stabilizes after time in most patients, and that treatment with rigid contact lenses is successful for many.

Until recently there has been no viable Keratoconus treatment available, and often patients were forced to undergo drastic corneal transplant surgery. A number of clinical studies have demonstrated, however, that progressive Keratoconus can be stabilised by means of corneal cross linking.
