Photorefractive Keratectomy

Photorefractive Keratectomy (PRK) is a type of refractive eye surgery used by ophthalmic specialists to reshape the cornea and improve vision. This surgical procedure is commonly used to treat nearsightedness, farsightedness, and astigmatism. During the PRK procedure, the surgeon uses an Excimer laser to precisely remove the outer layer of the cornea, known as the epithelium. Once the epithelium has been removed, the surgeon applies the laser treatment to the cornea to reshape its curvature. By altering the shape of the cornea, the PRK procedure can help to correct vision problems, such as blurred vision, halos or starbursts while driving at night, and other optical aberrations. One of the main advantages of PRK surgery is that it does not require any incisions to be made in the cornea, which minimizes the risk of complications. PRK is also typically associated with faster recovery times than other types of refractive surgery, such as LASIK. However, due to the removal of the epithelium, PRK has a slightly longer recovery period compared to other procedures. Patients may experience temporary discomfort or sensitivity in the eyes, and it may take a few days for vision to fully stabilize. PRK is a safe and effective procedure that has helped many people to achieve clearer vision. If you are looking for corrective eye surgery, consult with an experienced ophthalmic specialist to see if PRK could be the right option for you.
