Photorefractive Keratectomy, commonly known as PRK, is a type of eye surgery used to improve vision by reshaping the cornea. This procedure is especially useful for patients with myopia (nearsightedness), hyperopia (farsightedness), and astigmatism. PRK has been a trusted method of vision correction for many years and serves as an excellent alternative to LASIK, particularly for those with thinner corneas or other specific eye conditions.
PRK works by removing the thin outer layer of the cornea, which allows the underlying corneal tissue to be sculpted with an excimer laser. The cornea then heals over time, resulting in improved vision. This method avoids the creation of a corneal flap, which is a key step in LASIK surgery, making PRK a better option for individuals involved in contact sports or those who are not suitable candidates for LASIK.
Understanding what PRK entails and how it benefits your vision can help you make an informed decision if you’re considering this procedure. It’s essential to know what to expect during the surgery and how to care for your eyes afterward to ensure a smooth recovery and long-lasting results.

What is Photorefractive Keratectomy (PRK)?
Photorefractive Keratectomy (PRK) is a type of laser eye surgery used to correct vision problems such as nearsightedness, farsightedness, and astigmatism. PRK works by reshaping the cornea – the clear, front part of the eye – enabling light to focus properly on the retina, which improves vision. This procedure is an excellent option for individuals who have thin corneas or other conditions that make them unsuitable candidates for other types of laser surgeries.
During the PRK procedure, the outer layer of the cornea, called the epithelium, is removed. This allows the surgeon to reshape the underlying corneal tissue with a laser, improving the way light is focused within the eye. The epithelium naturally grows back over a few days, during which time patients may experience some discomfort. However, this minimally invasive procedure generally leads to significant vision improvement and long-lasting results.
Key Benefits and Advantages of PRK
PRK offers several key benefits and advantages for those seeking vision correction. One of the main benefits is its suitability for individuals with thinner corneas, making it a viable option for those who may not qualify for other laser surgeries. In addition, PRK eliminates the risk of flap complications, as no corneal flap is created during the procedure.
PRK also tends to provide excellent long-term vision correction outcomes. Many patients experience significant improvements in their vision, reducing or even eliminating their dependence on glasses or contact lenses. The procedure is also known for its precision and safety, with advanced laser technology allowing for highly accurate reshaping of the cornea. These benefits make PRK a compelling choice for achieving clear and improved vision.

Step-by-Step Guide to the PRK Procedure
Understanding the steps involved in PRK can help you feel more prepared and relaxed about the process. The procedure begins with numbing eye drops to ensure comfort. Once your eyes are numb, the surgeon gently removes the outer layer of the cornea, the epithelium. This step is crucial as it allows direct access to the corneal tissue that needs reshaping.
Next, a specialized laser is used to carefully reshape the corneal tissue. This part of the procedure is guided by a computer for ultimate precision. The laser adjusts the curvature of the cornea to correct the vision problem. After the laser treatment, a soft contact lens is placed on the eye to protect it while the epithelium regenerates. This lens functions as a bandage for the first few days of healing.
Post-PRK Care: Tips for a Smooth Recovery
Taking good care of your eyes after PRK is essential for a smooth and successful recovery. Immediately following the surgery, you may experience blurred vision, eye soreness, and sensitivity to light. These symptoms are temporary and usually resolve within a few days. To help with the healing process, we provide detailed aftercare instructions, including the use of prescribed eye drops to prevent infection and reduce inflammation.
It’s important to follow these instructions closely and attend all follow-up appointments to monitor the healing progress. We recommend avoiding strenuous activities and protecting your eyes from bright light and dust. Wearing sunglasses can help alleviate light sensitivity. Keep your hands clean and avoid touching your eyes to reduce the risk of infection. Following these care tips will help ensure a smooth recovery and the best possible outcome for your vision.
Conclusion
PRK eye surgery is a highly effective and safe option for vision correction, offering numerous benefits for those looking to improve their eyesight.
