Corneal collagen cross-linking (CXL) is a method used to treat keratoconus. Keratoconus is an eye condition in which the cornea (the clear surface of the eye) becomes thin and bulges outward in a cone-shape, causing blurry vision. This common disease affects about 1 in 750 Americans.
How does CXL work?
In normal corneas, there are crosslinks between the collagen fibers that keep the cornea strong and able to retain its normal shape. With keratoconus, these crosslinks are weakened and unable to keep the cornea shaped properly. This causes the cornea to bulge outward.
The aim of CXL is to strengthen these collagen cross-links, making the cornea more stable and improving focus power. CXL cannot cure or reverse keratoconus, but has been shown to stop the progression of it.
The Procedure
The CXL procedure is fairly simple, and is performed on an outpatient basis. Only numbing drops and a mild sedative will be used. During the procedure, the doctor will apply liquid riboflavin (vitamin B2) to the surface of the cornea, and then apply a controlled amount of ultraviolet light.
There are two basic types of corneal cross-linking:
- Epithelium-off. This type of cross-linking procedure requires the doctor to remove the thin outer layer (epithelium) from the cornea. This allows the liquid riboflavin to better penetrate the inner layers of the cornea.
- Epithelium-on. The outer corneal layer is left intact, needing a longer period of time for the riboflavin to penetrate the cornea.
Corneal Cross-Linking Technology
Stahl Eyecare Experts is one of very few practices in New York to use Avedro’s new KXL® system. This innovative technology is the only FDA approved cross-linking device for keratoconus. After extensive clinical trials, the Avedro KXL® system has proven to be extremely successful in the treatment of keratoconus.
Stahl uses the riboflavin solutions from Avedro, Photrexa Viscous® and Photrexa®, along with the KXL® system. This system offers extreme accuracy and a fully integrated platform.
