Full Form of PRK

What is PRK?

Photorefractive Keratectomy (PRK) is a type of laser eye surgery used to correct refractive errors such as myopia, hyperopia, and astigmatism. Unlike LASIK, PRK does not involve creating a corneal flap; instead, the outer layer of the cornea (epithelium) is removed and the underlying tissue is reshaped using an excimer laser. This procedure is particularly suitable for patients with thin corneas or those involved in contact sports where flap complications could be a concern. In India, PRK has gained popularity in ophthalmology clinics and hospitals as an alternative to LASIK, especially among military personnel and athletes. It is typically performed as an outpatient procedure under local anaesthesia. The recovery period is longer than LASIK, with initial discomfort and gradual vision improvement over several weeks. PRK is often included in the curriculum for MBBS and ophthalmology postgraduate exams, making it relevant for medical students preparing for NEET PG or similar assessments. Its safety and efficacy have made it a trusted option in Indian eye care, with many centres offering advanced laser technology.
