Corneal Collagen Cross-Linking

For years keratoconus patients had no treatments options available that would prevent their condition from getting worse. Rigid contact lenses and corneal inserts are used to improve vision for keratoconus patients, but in many cases the vision will continue to deteriorate. For some patients-if the keratoconus becomes too severe-a corneal transplant becomes the only option.

Fortunately, keratoconus patients now have an effective way to slow or halt the progression of this eye disease. Corneal Collagen Cross-Linking with riboflavin (CXL or sometimes also abbreviated as C3R) has been proven to strengthen the eyes' natural collagen fibres, resulting in a stiffer cornea. CXL doesn't improve vision, but it can prevent your vision from deteriorating, therefore greatly reducing the need for a corneal transplant in the future. CXL also helps to facilitate the use of contact lenses.

How Corneal Collagen Cross-Linking works

Step 1:
Topical anesthetic eye drops are applied to numb the eye. The surface or epithelium of the cornea is then carefully polished using an epithelial brush.

Step 2:

The eye is treated with an application of riboflavin eye drops. These must remain on the eye for 30 minutes.

Step 3:

In the final step of CXL, UV-A light is administered to the eye for 30 minutes, causing the collagen cross-linking bonds to form.
