PRK (Photorefractive Keratectomy)
PRK, also known as Photorefractive Keratectomy, is one of the earliest forms of laser eye surgery and still remains a highly effective and trusted method for vision correction. It is commonly performed to treat refractive errors such as nearsightedness, farsightedness, and astigmatism. Unlike LASIK, which involves creating a corneal flap, PRK works by gently removing the thin outer layer of the cornea called the epithelium and then reshaping the underlying corneal tissue with an excimer laser. This process changes the way light enters the eye, helping patients achieve clearer and sharper vision without relying on glasses or contact lenses.
PRK is often recommended for individuals who may not qualify for LASIK due to thin corneas, irregular corneal shapes, or specific eye health conditions. Because there is no corneal flap created, PRK is also preferred by patients with active lifestyles or professions where eye injuries are more likely, such as athletes or military personnel. The procedure is safe, precise, and provides long-lasting results, making it a valuable option for those seeking permanent vision correction.
The procedure itself is relatively quick, usually taking less than 15 minutes per eye. Before the surgery, numbing drops are applied to ensure the patient feels no pain. The surgeon carefully removes the epithelium and then uses the laser to reshape the cornea with extreme accuracy. A temporary protective contact lens is placed on the eye after the procedure to aid the healing process. While the surgery itself is short and straightforward, recovery is typically slower compared to LASIK because the epithelium needs time to regenerate. Patients usually experience some discomfort, light sensitivity, or blurred vision during the initial days, but vision gradually improves as healing progresses. Within a few weeks, most patients notice significant improvements, and full results become stable within a few months.
PRK does come with some temporary side effects. Common issues during recovery include dry eyes, glare, or halos around lights, especially at night. However, with advances in laser technology and post-operative care, serious complications are rare. Patients who carefully follow their doctor’s aftercare instructions usually achieve excellent outcomes with minimal risk. Over time, the majority of patients enjoy clear, stable vision that lasts for many years.
One of the biggest benefits of PRK is its long-term reliability. Many patients who undergo PRK achieve 20/20 vision or better, and the results tend to remain stable. Since there is no corneal flap created, the risk of flap-related complications is eliminated, which makes PRK a safer choice for some individuals. Compared to LASIK, the main difference is the longer recovery period, but once healing is complete, the visual outcomes are very similar.
Choosing PRK means choosing a proven method of vision correction that has helped millions of people worldwide. It offers freedom from glasses and contact lenses, a better quality of life, and the reassurance of a well-established surgical technique. If you are considering laser eye surgery, PRK is worth discussing with your ophthalmologist to determine if it is the best procedure for your specific needs. With its high success rates, safety, and effectiveness, PRK continues to be a leading option for achieving clearer vision and long-lasting results.
