Laser vision correction has helped many people reduce their dependence on glasses. But not every eye suits every procedure, and some eyes are better left untreated. A thorough suitability check is the most important step.
What decides suitability?
- A stable spectacle prescription for about a year
- Adequate corneal thickness and a regular corneal shape
- Healthy tear film and no active eye disease
- Realistic expectations after counselling
Comparing the main options
i-LASIK uses a laser to create a thin corneal flap before reshaping the tissue beneath. Contoura Vision is a topography-guided form of LASIK planned around your corneal map. PRK reshapes the surface without a flap and can suit thinner corneas. ICL places a lens inside the eye and may be considered for high prescriptions.
What about reading glasses after 40?
Presbyopia — difficulty focusing up close with age — is a separate natural change. Laser correction for distance vision does not prevent it, and your surgeon can discuss options.
The best procedure is the one that is safest for your eyes. A pre-LASIK work-up will tell you which options are available to you.
