What is PRK surgery?

PRK (Photorefractive Keratectomy) was the precursor of laser refractive surgery and remains an excellent option, especially for patients with thinner corneas or certain ocular surface conditions that aren't candidates for LASIK.

Unlike LASIK, PRK doesn't create a corneal flap: the cornea's outermost layer (epithelium) is removed and the surface is reshaped directly with an excimer laser. The epithelium regenerates naturally over the following days, while a temporary bandage contact lens protects the cornea.

Visual recovery is a bit more gradual than with LASIK — some discomfort and light sensitivity in the first few days is normal — but long-term results are comparable and highly predictable.
