Corneal cross-linking (CXL) is a minimally invasive procedure designed to strengthen the cornea and halt the progression of keratoconus and related ectatic disorders. It works by increasing natural ‘cross-links’ between collagen fibres in the cornea.
How the Procedure Works
After numbing drops, vitamin B2 (riboflavin) drops are applied to the cornea and activated with controlled ultraviolet-A light. This reaction forms additional bonds between collagen fibres, stiffening the corneal tissue.
- Usually performed as a day-case procedure
- Both eyes may be treated on the same day or separately
- Vision is often blurred for a period while the surface heals
Benefits of Cross-Linking
CXL is the only treatment proven to stop keratoconus from getting worse in most patients, greatly reducing the risk of needing a corneal transplant. Some patients also notice improved vision once the cornea stabilises.
