LASEK and PRK are surface laser techniques used when LASIK or SMILE are not ideal. Suitability depends mainly on corneal thickness, shape, and lifestyle.
Who might benefit from LASEK
In LASEK, the surface layer epithelium is loosened with alcohol then replaced after laser treatment. Some surgeons prefer it for certain prescriptions or when flap creation is best avoided.
- Useful in thinner corneas where preserving tissue is important
- May suit patients at higher risk of eye trauma, such as contact sports players
- Healing time and discomfort are moderate, often a few days
- Visual recovery is usually gradual over several weeks
Who might benefit from PRK
PRK removes the surface epithelium completely before laser reshaping. The surface then regrows under a bandage lens.
- Often chosen for irregular or scarred surfaces where epithelium is unhealthy
- Similar candidates to LASEK in terms of thickness and prescription
- Pain and light sensitivity can be stronger in the first few days
- Your surgeon will recommend the most suitable surface technique
