Making a decision to have LASIK

Suitability for LASIK depends on the amount and type of refractive error, the curvature and thickness of your cornea and a number of other factors.

People who are most satisfied with the results of laser correction have realistic expectations of the outcome and clearly understand the minimal potential risks and side effects.


  • Minimum age: 20 years
  • Stable vision (spectacle prescription) for at least 1 year
  • Absence of other eye diseases, especially those affecting the cornea
  • Not pregnant or breastfeeding


Modern laser refractive surgery is very safe and effective, with most people being very happy with the results. We commonly hear that it is the best thing they have ever done and wished they did it years ago.

You do need to be aware that the procedure is performed on living tissue and at times the cornea can react to the laser in ways we cannot measure beforehand, hence there may be some variability with the results.

What this means is that your unaided vision after LASIK may not be quite as good as it is now with your glasses or contact lenses and it may not be possible for us to improve it. Often the vision in one eye will turn out to be slightly better than the other when tested individually.

We aim to reduce your need for glasses in most situations but there may be some instances such as driving at night or for extended periods of focusing at short distances (for example reading) where you still may require them.

Please note, some redness immediately after LASIK surgery is common, especially where the white meets the clear part of your eye. These red patches are like small bruises and will clear over the first month. They are nothing to be worried about.
