# Is PresbyMAX surgery suitable if prescription is stable?

A stable prescription is an important requirement and strongly supports suitability for PresbyMAX.

## What stability involves

Consistency improves predictability.

- Little or no change in sphere or cylinder over 12-24 months
- No ongoing trend of increasing myopia, hyperopia, or astigmatism
- Similar results between different optometrists or visits
- Absence of conditions like keratoconus that drive progressive change
- Confidence that laser targeting will remain appropriate for years

## Why this matters

PresbyMAX fixes a specific refraction.

- Reduces risk of early regression or new imbalance between eyes
- Helps achieve stable distance and near outcomes
- Supports long‑term satisfaction with reduced spectacle dependence
- Fits standard safety guidance for all refractive laser procedures
- Unstable prescriptions are usually monitored before surgery is considered
