Treatment
Corneal Cross-Linking
Corneal cross-linking (CXL) strengthens the cornea to halt the progression of keratoconus and post-refractive ectasia using riboflavin and UV light.
Overview
Understanding the Procedure
Corneal cross-linking (CXL) is a minimally invasive procedure that strengthens the collagen bonds within the cornea. It is the gold-standard treatment for halting the progression of keratoconus — a condition where the cornea thins and bulges into a cone shape, causing distorted vision.
During the procedure, riboflavin (vitamin B2) drops are applied to the cornea, followed by controlled ultraviolet-A (UVA) light exposure. This combination creates new cross-links between collagen fibres, stiffening and stabilising the cornea.
Cross-linking does not reverse existing keratoconus but prevents further deterioration, preserving the patient's current level of vision and potentially avoiding the need for a corneal transplant in the future.
Miss Tina Khanam is a corneal specialist with extensive experience in managing keratoconus. She performs both epithelium-off (standard) and epithelium-on (transepithelial) cross-linking techniques depending on the individual case.
Benefits
What This Means for You
- Halts keratoconus progression in over 95% of cases
- May prevent the need for corneal transplant
- Minimally invasive day-case procedure
- Can be combined with other treatments (e.g. intrastromal ring segments)
- Proven long-term stability — effects last 10+ years
Our Approach
Consultant-Led Care
Miss Khanam conducts thorough corneal imaging including topography, tomography, and pachymetry to assess the stage and progression of keratoconus before recommending cross-linking.
Treatment is typically recommended for progressive keratoconus — where serial scans show the cornea is continuing to thin or steepen. Early intervention produces the best long-term outcomes.
Suitability
Is This Right for You?
- Patients with progressive keratoconus
- Post-refractive surgery ectasia
- Young adults where keratoconus is more likely to progress
- Patients with corneal thickness of at least 400 microns
Common Questions
Frequently Asked Questions
Cross-linking is primarily designed to stabilise the cornea and prevent further deterioration. Some patients do experience a modest improvement in vision as the cornea stiffens, but this is not the primary goal.
Anaesthetic drops are used during the procedure. Afterwards, there can be moderate discomfort for 2-3 days as the corneal surface heals. Pain relief is provided.
Usually one session per eye is sufficient. In rare cases where progression continues, a repeat treatment may be considered.
In some cases, once the cornea has stabilised (usually after 12 months), further refractive procedures may be considered. Miss Khanam will advise on the safest approach.
