# Laser Eye Surgery Cost by Prescription Strength

Prescription strength influences the complexity of laser planning and therefore affects cost. Higher prescriptions require more sophisticated ablation profiles and stricter biomechanical safety thresholds.

**Why higher prescriptions cost more**

- Greater tissue removal requires larger optical zones and deeper ablations.
- Custom wavefront/topography-guided profiles are often needed.
- Advanced eye-tracking is required for high astigmatism.
- Biomechanical modelling becomes more critical to avoid ectasia. ¹

These factors increase planning time, technology input, and platform licensing.

**Predictability and enhancement rates**

Outcomes remain excellent across prescription ranges, but enhancement rates are slightly higher in very high prescriptions. ² Clinics may incorporate this into pricing or enhancement policies.

**Typical UK ranges**

Higher prescriptions often fall toward the upper end of the £1,500-£3,000 per eye range due to customisation requirements.

**Suitability considerations**

Patients with very high prescriptions may be better suited to ICL, depending on corneal thickness and biomechanical metrics.
