PRK

Photorefractive Keratectomy (PRK) is another type of refractive surgery used to correct vision problems similar to LASIK. Unlike LASIK, which involves creating a flap in the cornea, PRK removes the outer layer of the cornea entirely. This outer layer, called the epithelium, is then allowed to regenerate naturally. PRK is suitable for patients with thin corneas or those at risk of flap complications. Recovery from PRK is typically longer compared to LASIK, as the epithelium takes time to heal. During this period, patients may experience discomfort and blurry vision. However, once the epithelium regenerates, vision gradually improves. Like LASIK, PRK offers high success rates in reducing dependence on glasses or contact lenses. It's essential for candidates to undergo thorough evaluations to determine suitability and discuss potential risks, such as infection and corneal haze. PRK remains a valuable option for individuals seeking long-term vision correction without the need for corneal flap creation.
