For most people, laser eye surgery does not cause problems later in life. The vast majority enjoy many years of clearer vision without serious long-term issues. However, no eye surgery is completely risk-free. A small number of people may notice side effects such as dry eyes, glare or a change in prescription over time, and the natural ageing of the eye (for example, needing reading glasses) still happens whether you have surgery or not.
Is Laser Eye Surgery Safe Long Term?
Modern techniques like LASIK, LASEK and SMILE have been used for many years and have a good long-term safety record when carried out on suitable candidates. Careful screening before surgery helps identify people for whom the procedure may not be appropriate. Your surgeon will explain the benefits, limitations and possible risks so you can make an informed decision.
What Long-Term Problems Are Possible?
Most side effects are mild and settle with time, but possible longer-term issues can include:
- Dry or gritty eyes that need lubricating drops
- Halos or glare around lights, especially at night
A slight change in prescription (regression), sometimes needing glasses or a further procedure
More serious complications are rare, but they can occur and may need additional treatment.
Will I Still Need Glasses in the Future?
Laser eye surgery reshapes the cornea, but it cannot stop the lens inside the eye from ageing. Many people will still need reading glasses later in life, whether or not they have had laser eye surgery. Your surgeon can talk through what this is likely to mean for you in the long term.
