Keratoconus Symptoms and Treatment
Keratoconus is a disease of the cornea in which a normally round, dome-shaped cornea progressively thins, causing a cone-shaped bulge to develop. Keratoconus is felt to be caused by a combination of genetic and environmental factors. The chief environmental trigger for this condition is repeated mechanical pressure on the cornea- either by eye rubbing or a face down sleep posture. The irregular shape of the cornea can cause decrease visual acuity, which may not be correctable with corrective lenses in severe keratoconus.
