Corneal cross-linking is a minimally invasive outpatient procedure that uses ultraviolet light along with specially formulated eye drops to stiffen and strengthen corneas that have been weakened by disease or refractive surgery. Cross-linking is considered the standard of care around the world for progressive keratoconus and corneal ectasia following refractive surgery.
The corneal cross-linking procedure creates new corneal collagen cross-links that result in a shortening and thickening of the collagen fibers, creating new, stronger links to create a more stable cornea shape. The goal of this procedure is to keep the cornea from bulging more and avoid major surgery. If symptoms of keratoconus become severe, you may need a corneal transplant. Keratoconus is a condition that causes corneal thinning and weakening over time which creates a bulge shape that distorts vision.
Corneal cross-linking does not reverse corneal damage that has already occurred, it keeps them from getting worse. If you are a keratoconus patient, it’s best to consult with your eye doctor as soon as possible.
