What is PRK Surgery?

Photorefractive Keratectomy (PRK) is an advanced laser eye surgery that corrects vision problems by reshaping the cornea using an excimer laser. Unlike LASIK, PRK doesn't create a corneal flap, making it suitable for patients with thin corneas or those involved in contact sports.

PRK can effectively treat nearsightedness (myopia), farsightedness (hyperopia), and astigmatism. The procedure removes the outer layer of the cornea (epithelium), reshapes the underlying corneal tissue, and allows the epithelium to regenerate naturally during healing.

While the initial recovery time is longer than LASIK, PRK offers excellent long-term visual outcomes with reduced risk of flap-related complications. Most patients achieve 20/20 vision or better within 3-6 months post-surgery.

Modern PRK techniques include advanced surface ablation methods like LASEK and Epi-LASIK, which provide faster healing and improved comfort compared to traditional PRK.
