KERATOCONUS IS A PREGRESSIVE CORNEAL EYE DISEASE in which the thickness of the cornea thins and the curvature begins to bulge into a steeper cone-like shape. This cone shape cornea causes light to scatter and defocus causing distorted vision.
In early stages, keratoconus causes slight blurred, distorted vision, and glare with increased light sensitivity. Keratoconus often starts in the teenage years to early 20’s. Often patients with good vision throughout their earlier life now suddenly and drastically have decreased vision. Each eye may have different severity of keratoconus.
Often, keratoconus patients experience is large fluctuation in their eyeglasses prescription and often times unhappy with their eyeglasses as the fluctuating eyeglass prescription can cause eyestrain and headaches.
Keratoconus have a genetic link and a hereditary component. It can run in families therefore it is a good idea to have family members screened for this condition.
