Both techniques correct prescription, but in different ways.
PRK and LASIK are laser refractive procedures used to correct myopia, astigmatism and hyperopia in selected candidates. The goal is to reshape the cornea to improve focus.
LASIK
In LASIK, a thin flap is created in the cornea. The laser is applied underneath, and the flap is repositioned. Visual recovery is often faster, but the cornea must meet safety criteria.
PRK
In PRK, the surface layer of the cornea is removed and heals over the following days. Initial recovery is usually slower and less comfortable than LASIK, but PRK may be more appropriate for some corneas.
Which is better?
There is no universal answer. Topography, tomography, corneal thickness, prescription stability, tear film and expectations matter.
If the cornea is thin, irregular or suspicious, the safest decision may be not to perform laser surgery.
Practical summary
The first question is whether surgery is safe for your eyes. Technique selection comes after that.
