Information About Cornea Procedures

As a protection for your vision, the cornea is a dome-shaped, translucent layer that covers the front of the eye to refract light and preserve sight.

Phototherapeutic keratectomy, or PTK, addresses a patient's vision impairment issues by removing the portions of the cornea that are uneven or cloudy.

By reshaping the cornea into a cone instead of a domed shape, keratoconus is a progressive eye condition that reduces vision and thins the cornea.

When performed before the cornea becomes too weak or misshaped, a cross-linking procedure can preserve or even enhance the contour of the cornea.

A full-thickness cornea transplant, DMEK or DSEK involves removing the damaged cornea from the eye and surgically replacing it with a donor cornea.
