Cross-linking is the only proven non-surgical method for treating keratoconus, which slows down or stops the progression of the disease.
During the procedure, the outermost layer of the cornea is removed, and the eye is exposed to ultraviolet (UV) light for 30 minutes. Then a soft contact lens or a bandage lens is placed for 4–5 days, during which initial healing occurs, and tearing and redness subside.
The goal of cross-linking is to create new collagen bonds within the cornea, strengthening the corneal tissue.
Advantages
- Stops or significantly slows the progression of keratoconus
- Reduces the risk of needing a corneal transplant
- In some patients, visual acuity improves
