Corneal Cross-Linking

What is Corneal Cross-Linking (CXL)?

CXL is an add-on procedure that is incorporated into your Safe Sight TransPRK procedure which helps to strengthen your cornea and lock-in the longevity of your post Safe Sight TransPRK vision. During laser vision correction procedures, the excimer laser reshapes the cornea by removing corneal tissue in order to correct refractive power. As such, thin and weakened corneas may be at risk of bulging forwards, resulting in a condition called Cornea Ectasia. CXL helps to reduce the risk of Cornea Ectasia.
At Clearvision, we use the Avedro KXL® System, designed by a team of scientists and engineers that delivers good results and is specially customised for integration with Safe Sight TransPRK procedures.

How does Corneal Cross-Linking (CXL) work?

CXL is a 3-minute procedure performed right after your Safe Sight TransPRK:
1. Safe Sight TransPRK procedure is performed
2. Riboflavin (Vitamin B2)* eye drops are applied to the cornea.
3 The riboflavin-soaked cornea is illuminated with ultra-violet A (UVA) light using technology of the Avedro KXL® System, and this treatment cross-links the collagen fibers within the cornea, thus strengthening the cornea.
*Riboflavin (Vitamin B2) aids in red blood cell production and helps release energy from carbohydrates, making it very helpful for body growth.

Why Corneal Cross-Linking (CXL) and is it right for me?

CXL strengthens the cornea of the eye and has the potential to:

  • Extend the longevity of Safe Sight TransPRK, decreasing the need for touch-up procedures
  • Improve the accuracy of Safe Sight TransPRK procedure
  • Reduce the potential for long-term changes in your vision
CXL is especially suitable for people with weaker, thinner cornea and/or people who have suffered from corneal injury, damage or scarring.
