CORNEAL COLLAGEN CROSS-LINKING

Corneal Collagen Cross-Linking strengthens a weakened cornea and helps slow or stop the progression of keratoconus and other corneal ectatic disorders. In keratoconus, the cornea becomes thin and bulges forward, which leads to distorted and blurred vision. Because the cornea plays a major role in focusing light, any change in its shape directly affects clarity. Therefore, stabilizing the cornea early is critical to protect long-term vision.

WHAT THIS SERVICE TREATS

This procedure primarily treats progressive keratoconus and post-refractive surgery corneal instability. In these conditions, the corneal structure weakens over time. As a result, patients may notice increasing astigmatism, frequent prescription changes, glare, or ghosting of images. Consequently, cross-linking aims to halt progression rather than to eliminate the need for glasses.

HOW THE PROCEDURE WORKS

First, the surgeon applies riboflavin eye drops to the cornea. Next, controlled ultraviolet-A light activates the riboflavin. Then, this interaction creates new chemical bonds between collagen fibers. Because these additional bonds strengthen the corneal framework, the cornea becomes more stable. Depending on corneal thickness and clinical findings, the surgeon may use an epithelium-off or epithelium-on technique.

WHO MAY BENEFIT

Doctors recommend Corneal Collagen Cross-Linking for patients who show documented disease progression. For example, increasing corneal steepness or worsening astigmatism may indicate progression. In addition, younger patients often benefit because keratoconus tends to advance more rapidly in early years. Therefore, early intervention can reduce the likelihood of future corneal transplantation.

1. Patients with progressive keratoconus
2. Individuals with post-LASIK corneal instability
3. Patients with documented corneal thinning progression
4. Selected cases of corneal ectasia

RECOVERY AND FOLLOW-UP

After treatment, patients may experience temporary discomfort, light sensitivity, and blurred vision. However, prescribed medications help manage symptoms. Vision may fluctuate during early healing; nevertheless, stabilization becomes the primary goal. Therefore, regular follow-up visits allow careful monitoring of corneal shape and thickness.

SAFETY AND CLINICAL VALUE

Extensive clinical research supports the safety and effectiveness of corneal cross-linking in slowing keratoconus progression. When proper screening and technique are used, complication rates remain low. Still, risks include infection, delayed healing, haze, or persistent discomfort. Consequently, the ophthalmologist performs comprehensive diagnostics before recommending treatment.
