A condition characterized by abnormal corneal change in which the cornea gradually becomes thinned and conical, affects approximately one in 2000 people in the United States. The cornea is the eye’s outermost layer. It is the clear, dome-shaped surface that covers the front of the eye. When light enters the eye it must hit a smooth regular surface in order for it to project a clear image on the retina. When light hits an uneven irregular surface, as in Keratoconus, the image is distorted.
Soft contact lenses and glasses can improve vision in the early stages of Keratoconus. As the condition progresses, rigid gas permeable (RGP) contact lenses may be needed to obtain acceptable vision. In our practice we also like to use semi-scleral lenses. These lenses feel as comfortable as soft contact lenses on the eye and provide the visual quality of a rigid gas permeable lens. Until now, if contacts became difficult to wear, a corneal transplantation was the last resort.
Intacs® is a FDA-approved procedure for patients with Keratoconus. Intacs® can improve vision and reduce the distortion caused by Keratoconus. Insertion of Intacs® is a minor outpatient procedure performed within 10 minutes with little if any discomfort. This procedure has proven effective for thousands of patients.
