Private corneal cross-linking costs from £1,800 to £3,500 per eye at Eye Surgery Clinic, with both eyes (treated sequentially, four to twelve weeks apart) typically £3,400–£6,500. Every price is all-inclusive of the corneal consultation, tomography, theatre, surgeon fee, riboflavin and UVA, the post-operative bandage contact lens, drops and one year of follow-up. A separate corneal consultation with tomography is £195–£350 and is credited against your CXL if you proceed.
What is corneal cross-linking?
Corneal collagen cross-linking is a 60–90 minute outpatient procedure that strengthens a thinning, weakened cornea by creating new bonds between collagen fibres in the corneal stroma. Riboflavin (vitamin B2) drops are applied, then the eye is exposed to ultraviolet-A light at 365 nm. The riboflavin acts as a photosensitiser, producing cross-links that increase the cornea’s biomechanical stiffness in the anterior stroma.
CXL is performed for two main indications: progressive keratoconus (an inherited dystrophy that thins and bulges the cornea into a cone, distorting vision) and post-refractive corneal ectasia after LASIK or PRK. It is approved by NICE (IPG466) and supported by the Royal College of Ophthalmologists keratoconus pathway. CXL does not improve vision in most cases — its purpose is to halt progression so vision can keep being corrected with glasses or specialist contact lenses, and so the patient avoids corneal transplantation later.
Corneal cross-linking prices
The cost depends on the protocol chosen with your surgeon at the consultation. Each tier is the all-inclusive per-eye package covering consultation, tomography, theatre, riboflavin, UVA, bandage contact lens, drops and one year of follow-up.
Both eyes treated sequentially (four to twelve weeks apart) typically total £3,400–£6,500. A repeat CXL for documented re-progression — needed in around 3–5% of cases at 5–10 years — is £1,800–£2,800. If keratoconus has advanced beyond what CXL can stabilise, our DMEK corneal transplant page covers endothelial transplant pricing, and the wider price list covers every procedure.
Is your keratoconus progressing? A corneal consultation with tomography and a formal progression analysis tells you whether CXL is needed now.
Book a CXL consultationWhat’s included in the price
Our CXL prices are fixed and all-inclusive. Each package covers:
- Consultant corneal surgeon consultation — history, refraction, slit-lamp and tear-film assessment
- Corneal tomography — Pentacam, Galilei or MS-39, with progression analysis
- Theatre, day-case admission and consumables in a CQC-registered unit
- Riboflavin and the UVA delivery system for your chosen protocol
- Post-operative bandage contact lens and drops — antibiotic, steroid and lubricant
- One year of follow-up with repeat tomography at 6 and 12 months to confirm stability
Only the initial consultation is quoted separately, and it is credited against your CXL if you proceed within three months.
Protocols, NHS and insurance
The standard epi-off (Dresden) protocol has the strongest long-term evidence; accelerated epi-off (KXL) compresses the same effect into a shorter UVA exposure with equivalent outcomes and is the default at most UK centres; epi-on (transepithelial) CXL leaves the epithelium intact for much less pain and faster recovery but a smaller effect, and is reserved for thin corneas and selected cases.
The NHS funds CXL for documented progression (Kmax increase ≥ 1.0 D, thinnest pachymetry decrease ≥ 30 µm, or refractive cylinder shift ≥ 1.0 D over 6–12 months), but 2026 waits run 12–52 weeks and progression continues during the wait. Major UK insurers (Bupa, AXA, Aviva, Vitality, WPA) usually cover CXL with a corneal-specialist referral, documented progression and pre-authorisation — see our guidance for insured patients. Self-pay stage payment is available via our finance options.
