Corneal Cross linking
Corneal cross-linking (CXL) is a treatment for patients with keratoconus which can prevent their condition getting worse. CXL is successful in preventing the condition deteriorating in more than 90% of cases. After treatment, you will still need to wear spectacles or contact lenses. Keratoconus gets worse because the cornea weakens. CXL, also known as C3R, uses ultraviolet light and vitamin B2 (riboflavin) drops to stiffen the cornea. Used together, they cause fibers within the cornea to cross-link – or bond more tightly. This treatment mimics the normal age-related stiffening of the cornea, which is known as natural cross-linking.
