Photorefractive keratectomy (PRK) is a type of laser eye surgery that reshapes the cornea without creating a flap. It is often recommended when the cornea is thinner or when flap-related issues need to be avoided.
How PRK works
The surface cells of the cornea are gently removed, and an excimer laser reshapes the underlying tissue to correct the prescription. A protective contact lens is placed on the eye while the surface layer heals.
- Recovery is slower than LASIK but results are similar
- Often chosen for people with thinner corneas or certain lifestyles
- Temporary discomfort and light sensitivity are common during healing
