Corneal Cross-Linking (CXL) is an advanced, in-office treatment that aims to strengthen and stabilize the cornea, the eye’s transparent outer layer. It is especially effective for conditions like keratoconus and corneal ectasia, where the cornea becomes thin and irregularly shaped. The procedure combines Riboflavin (Vitamin B2) drops and Ultraviolet (UV) light to create cross-links between collagen fibers in the cornea, making it more rigid and preventing further deformation. By halting progression, CXL helps preserve your vision.
Corneal Cross-Linking (CXL) works by strengthening and stabilizing the cornea through the creation of new cross-links between collagen fibers, the structural proteins that maintain the cornea’s shape. In this procedure, Riboflavin (Vitamin B2) eye drops are applied to the corneal surface, where they penetrate and saturate the tissue.
The eye is then exposed to a controlled amount of Ultraviolet (UV) light, which activates the riboflavin. This triggers a chemical reaction that forms new bonds between collagen molecules, increasing the cornea’s rigidity.
During your session with Dr. Hu, the epithelial layer of your cornea is carefully removed to enhance the absorption of Riboflavin (Vitamin B2) eye drops into the corneal stroma. Once the cornea is fully saturated, it is exposed to controlled ultraviolet-A (UV-A) light for 30 minutes. This activates the riboflavin, generating reactive oxygen species that create new cross-links between collagen fibers, increasing the cornea’s strength and rigidity. Afterward, a bandage contact lens is placed to protect the cornea and promote epithelial healing, which occurs within a few days.
After your corneal cross-linking procedure, you may experience mild discomfort, light sensitivity, and blurry vision as your cornea heals. These symptoms are normal and typically improve within a few days. Dr. Hu will provide medicated eye drops to prevent infection, reduce inflammation, and promote healing. A bandage contact lens will remain in place for a few days to protect your cornea. While full visual recovery can take several weeks, most patients notice gradual improvements in vision stability and comfort.
With corneal cross-linking performed by Dr. Hu, you can expect a significant halt in the progression of keratoconus or corneal ectasia. While the procedure aims to stabilize your cornea and prevent vision loss, many patients also notice improved contact lens tolerance over time. It’s important to understand that CXL does not correct refractive errors, so you may still need glasses or contact lenses for clear vision. Dr. Hu will closely monitor your progress to ensure optimal results and long-term eye health.
CXL is not typically painful, as numbing eye drops are used during the procedure. Some patients experience mild discomfort, light sensitivity, or irritation during healing, which usually subsides within a few days.
The entire corneal cross-linking procedure takes about an hour per eye. This includes preparing your eye, applying Riboflavin (Vitamin B2) drops, and exposing the cornea to UV-A light for approximately 30 minutes.
You may need to take a few days off work and limit your activities while your cornea heals. During recovery, your vision may be blurry, and light sensitivity is common. Dr. Hu will provide personalized recommendations based on your progress.
The primary goal of corneal cross-linking is to stabilize the cornea and halt the progression of keratoconus or corneal ectasia. While the procedure does not directly improve refractive errors, many patients report better contact lens tolerance and improved visual quality over time as the cornea becomes more stable.
