Private corneal cross-linking (CXL) for keratoconus costs from about £1,800 per eye in the UK in 2026, or roughly £3,400–£6,500 for both eyes. The price is normally all-inclusive of consultation, corneal scans (tomography), the procedure and follow-up. CXL strengthens the cornea by creating new bonds between collagen fibres, halting the bulging and thinning that drive keratoconus — which is why treating early, before vision deteriorates, gives the best long-term outcome.
How much does corneal cross-linking cost?
Price depends on the technique, the clinic and whether one or both eyes are treated. As a 2026 UK guide:
See the full national breakdown on our corneal cross-linking cost page, or read about specific protocols such as iLink (Avedro) CXL and iontophoresis CXL.
What's included in the price?
A transparent CXL package should include: consultant cornea assessment, corneal tomography/topography to confirm progression and map the cornea, the cross-linking procedure itself (riboflavin drops plus controlled UV-A light), post-operative drops, and follow-up reviews — typically over the first year. Always check whether the quote is per eye or for both eyes, and which protocol is used.

Keratoconus causes the cornea to thin and bulge into an irregular cone, distorting vision over time. Left untreated in a progressing eye, it can lead to the need for a corneal transplant. CXL is the only treatment shown to stabilise the cornea and stop progression, which is why it is recommended early once progression is confirmed. It does not usually reverse existing distortion, but it protects the vision you have — and may be combined with, or followed by, vision-improving options.
