Corneal collagen cross-linking is a technique that was first used in 1998 to treat patients with a disease called keratoconus. In keratoconus, the cornea (the front clear window of the eye) can become weak, thin, and irregularly shaped. Instead of keeping their normal round shape, corneas with keratoconus can bulge forward into the shape of a cone causing poor vision. CXL is now being performed for patients with this condition in approximately 450 centers throughout the world. Through a research study, our practice is now able to provide this investigational treatment to our patients using advanced technology for cross-linking.
