PRK, which stands for Photorefractive Keratectomy, is a type of laser eye surgery that is often used to correct vision problems such as nearsightedness, farsightedness, and astigmatism. During PRK surgery, the outer layer of the cornea, called the epithelium, is removed in order to reshape the cornea and improve the way light enters the eye.

Unlike LASIK surgery, which creates a flap in the cornea, PRK surgery involves the complete removal of the epithelium. This makes PRK a better option for individuals with thin corneas or other corneal irregularities that may make LASIK surgery unsuitable.

After the epithelium is removed, a computer-controlled laser is used to reshape the cornea by removing tiny amounts of tissue. This precise reshaping allows light to focus correctly on the retina, improving vision. The procedure is typically quick and performed on an outpatient basis.

Recovery from PRK surgery can take longer compared to LASIK, as the epithelium needs time to regenerate. Patients may experience some discomfort, blurry vision, and sensitivity to light during the initial days following surgery. It is important to follow post-operative instructions provided by your eye surgeon to ensure proper healing and good outcomes.

PRK surgery has a high success rate in correcting vision problems, with many patients achieving 20/20 vision or better after the procedure. However, like any surgical procedure, there are potential risks and complications associated with PRK, so it is important to discuss your individual circumstances with an eye care professional to determine if PRK is the right option for you.

Overall, understanding the basics of PRK surgery can help you make an informed decision about whether it is the right choice for improving your vision. It is important to consult with a qualified eye surgeon to discuss your options and determine the best course of action for your specific needs.
