A stable prescription is one of the key requirements for ICL surgery and strongly supports suitability.
What “stable” usually means
Consistency reduces surprise outcomes.
- Little or no change in prescription over 12-24 months
- No pattern of steadily increasing myopia or astigmatism
- Similar measurements between different clinics or visits
- Absence of underlying conditions like keratoconus that drive change
- Confidence that chosen ICL power will remain appropriate for years
Why stability matters
Surgery fixes a particular prescription.
- Reduces the risk of needing early enhancement or lens exchange
- Helps achieve predictable visual outcomes
- Supports long‑term satisfaction with reduced spectacle dependence
- Forms part of standard refractive surgery safety criteria
- Unstable prescriptions are usually observed until they settle
