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.
