Corneal Cross-Linking

Corneal Cross-Linking: Halting Progression- Corneal Cross-Linking (CXL) is a minimally invasive medical procedure designed to strengthen the cornea and stop the progression of Keratoconus. It does not reverse the existing bulging but aims to prevent it from getting worse, thereby preserving the current level of vision. The procedure works by creating new chemical bonds, or "cross-links," between the collagen fibers within the cornea. Think of it like adding rungs to a ladder, making the entire structure much more rigid and stable.

The CXL Procedure: * The eye is numbed with anesthetic drops. * The thin outer layer of the cornea (the epithelium) is gently removed to allow for better absorption. (This is the "Epi-Off" method; an "Epi-On" method also exists). * Riboflavin (Vitamin B2) eye drops are applied to the cornea for about 30 minutes, saturating the tissue. * The cornea is then exposed to a controlled amount of ultraviolet (UV-A) light for a specific duration. The UV light activates the riboflavin, which in turn forms the new, strengthening cross-links. CXL is the only treatment proven to effectively halt the progression of Keratoconus.
It is often recommended for patients, especially younger ones, whose condition is still advancing. After the procedure, patients will still need glasses or specialty lenses (like scleral lenses) to see clearly, but the underlying condition is stabilized.
