Eye Conditions and Treatment

Keratoconus is treated in the Contact Lens Service and the Cornea Service


Keratoconus is an eye condition in which the shape of the cornea becomes distorted. The cornea is a clear structure that covers the front of the eye and allows light to enter the eye. In a healthy eye, the cornea curves like a dome. In an eye with keratoconus, the center of the cornea slowly thins and bulges, so that it sags and has a cone shape.
