A stable prescription is an important part of being suitable for lens replacement surgery, especially when planning precise visual outcomes.
Why stability matters
When your glasses prescription has not changed much for several years, results are more predictable. The measurements used to choose your lens implant are then more likely to match your long-term focusing needs.
- Stable prescription usually means no significant change for at least two years
- Makes it easier to target clear distance or blended vision
- Reduces the chance of needing early extra corrections
- Suggests that the eye has finished major growth or age-related change
- Gives you more confidence in the planned outcome
Other checks alongside stability
Even with a steady prescription, other factors must be right. Your surgeon will look at the whole eye and your lifestyle to decide whether surgery is sensible.
- Healthy cornea, retina, and optic nerve are essential for sharp vision
- General health and medications are reviewed for safety
- Expectations about glasses use after surgery are discussed clearly
- Dry eye or eyelid problems may need treatment beforehand
- Regular follow-up ensures that results remain stable over time
