The word Keratoconus comes from two Greek words: kerato (cornea) and konos (cone). Keratoconus is a degenerative disorder of the eye in which the shape of the cornea, which is usually round, is distorted and develops a cone-shaped bulge, resulting in reduced vision. Keratoconus is a relatively common condition. It affects one person in two thousand, occurs around the world and is quite common in the Middle East.
Progression of Keratoconus depends on the patient’s age at the time of onset and the severity of eye rubbing. The earlier the onset, the faster Keratoconus may progress. The condition always affects both eyes and is asymmetric, so one eye may be more affected than the other.
