Keratoconus Eye Care
Keratoconus is a progressive, debilitating eye disease in which the cornea thins causing an irregular bulging of the normally round, spherical cornea (the clear covering in front of the eye), resulting in grossly distorted vision. Symptoms of keratoconus include glare, photophobia, halos around lights, decreased vision, and monocular diplopia (double vision).
Keratoconus usually starts with mild symptoms beginning in the late teens and early twenties. Once it has progressed to a certain point, the decreased vision cannot be corrected with glasses or conventional contact lenses. However, most keratoconus patients can achieve functional vision with specially designed therapeutic contact lenses.
A uniquely designed keratoconic contact lens improves vision by creating a smooth, regular optical surface over the patient’s very irregular, cone-shaped cornea. By masking the distorted vision caused by keratoconus, these lenses can provide the required visual acuity necessary to perform daily routines.
If keratoconus progresses past the point where these contact lenses can no longer provide adequate vision, corneal transplant surgery may be necessary.
