Keratoconus is a degenerative disorder of the eye that affects the structure of the cornea. The cornea is the clear tissue covering the front of the eye. The shape of the cornea slowly changes from the normal round shape to a cone shape. The eye bulges out. This causes vision problems.
Keratoconus can cause substantial distortion of vision, with multiple images, streaking and sensitivity to light all often reported by the patient. It is typically diagnosed in the patient’s adolescent years. If afflicting both eyes, the deterioration in vision can affect the patient’s ability to drive a car or read normal print.
