Keratoconus is a progressive thinning eye disorder in which the normally round cornea begins to bulge into a cone-like shape. In patients with keratoconus, the cone-shaped cornea deflects light and causes distorted vision.
Keratoconus often begins to develop between the teen years and the early 20s, although it can develop at any age. Changes in the shape of the cornea occur gradually, usually over several years. Patients with keratoconus often experience blurred and distorted vision, nearsightedness, and a glaring sensitivity to light.
Early stages of keratoconus can be treated with glasses or soft contact lenses. For progressive keratoconus, treatment methods include rigid gas-permeable contact lenses, INTACS or KERARINGS(implants that flatten the cornea), and collagen cross-linking (vitamin B2 eye drops and UV light exposure). Collagen cross linking is a safe and effective new development that halts the progression of keratoconus.
If keratoconus persists or is severe, corneal transplant surgery can be performed to correct the condition.
