Corneal thickness does not directly change the price of laser eye surgery, but it determines suitability, and suitability influences the treatment pathway.
Why thickness matters
Laser requires a safe residual stromal bed (RSB) and acceptable Percent Tissue Altered (PTA). ¹ Thin corneas or high ablation depths may increase ectasia risk, shifting patients toward:
- Surface ablation (PRK/LASEK)
- ICL
- No surgery if biomechanics are unsafe
How this affects cost
- Surface ablation may involve longer follow-up, therapeutic lenses, and additional medications.
- ICL is a different cost category entirely due to the bespoke implant.
- Enhanced diagnostics (epithelial mapping, tomography) may be required.
Typical UK ranges
Laser pricing remains within £1,500-£3,000 per eye, but borderline corneas may require alternative procedures with different cost structures.
Safety first
Ethical centres prioritise biomechanical safety over expanding suitability. Cost discussions follow anatomical assessment.
