Corneal Cross-Linking (CXL)

Corneal cross-linking (CXL) from €2,700

CXL is the only treatment that directly slows or stops progressive keratoconus, by strengthening the cornea's internal structure — available from €2,700 for both eyes at our partner ophthalmology hospitals across Turkey.

Package details

• Corneal topography and thickness (pachymetry) measurement
• CXL procedure, both eyes
• Surgeon and hospital fees
• Post-operative check-ups and medication

How the procedure works

Riboflavin (vitamin B2) drops soak into the cornea and are then activated with UV light, forming new molecular bonds between collagen fibers that make the tissue stiffer and more resistant to further bulging. Two approaches exist: "epithelium-off," where the thin surface layer is removed first for deeper riboflavin penetration, and "epithelium-on" (trans-epithelial), which is gentler but may be less effective in some cases — your surgeon recommends based on corneal thickness.

A treatment to stop things getting worse, not to fix them

It's important to set the right expectation: CXL halts progression, it isn't designed to reverse the corneal thinning or improve your prescription. Some patients do see modest visual improvement as the cornea regularizes slightly, but the main goal is stopping the disease where it is now. For patients who also want to improve day-to-day vision, CXL is often paired with intracorneal ring segments. MedAgent coordinates your corneal specialist appointment, procedure and stay in Turkey, and can arrange CXL and ICR as a single trip if your surgeon recommends both.

Steps to book

1. Send a recent topography scan showing keratoconus progression
2. Get a quote and treatment plan from the corneal specialist
3. Travel to Turkey for the procedure, both eyes usually together
4. Stay for the first check, then follow up as the eye heals

Questions patients ask

How do I know if my keratoconus is progressing? Progression is confirmed by comparing topography scans over time — a single scan alone usually isn't enough to decide.

Does the epithelium-off method hurt more? It typically means more discomfort for the first few days while the surface heals, compared with the epithelium-on approach, which your surgeon will discuss based on your case.

Will I need CXL again in the future? Re-treatment is uncommon but possible if progression resumes years later, which is why periodic topography checks continue after treatment.
