Lens replacement surgery is usually not recommended if your prescription is still changing, because results may be less stable and you might need further correction sooner.
Problems with changing prescriptions
When your glasses strength is shifting, it suggests the eye is still altering. Fixing a permanent implant during this time can leave you with unexpected blur in the future.
- Frequent changes in distance or reading glasses over recent years
- Ongoing shift in myopia, hyperopia, or astigmatism measurements
- Higher chance of needing additional glasses or enhancement after surgery
- Difficult to choose the best long-term lens power
- May be better to wait until the prescription settles
Exceptions and individual decisions
There are occasional situations where surgery is considered despite change, such as significant cataract. Your surgeon will explain the trade-offs and help you decide whether to proceed or delay.
- Rapid cataract progression affecting safety, work, or independence
- Difficulty tolerating glasses or contact lenses due to big differences between eyes
- Other eye conditions that make waiting unwise
- Understanding that further treatments or glasses may still be needed
- Close monitoring afterwards to track any continued prescription change
