PRK was the first-generation laser eye surgery treatment designed to correct astigmatism, myopia (near-sightedness) and hyperopia (far-sightedness). The procedure works by reshaping the cornea using an excimer laser.
First anaesthetic drops are applied to the patient’s eye to numb the area and prevent all discomfort during the treatment, then a device is used to hold the eyelids apart to avoid the eye blinking. The surgeon gently removes the outer layer of the cornea so an area is exposed for a laser to reshape the cornea. The laser reshapes the cornea so light can enter the eye and properly focus on the retina allowing for clear vision.
After the treatment, a soft contact lens is places onto the cornea to protect your eye. The recovery time for PRK is longer LASIK and LASEK laser eye surgery because it can take several days for new epithelial cells to regenerate and cover the surface of the eye. This can cause patients more discomfort during the first few days of recovery. However, compared to other laser eye surgery treatments, such as LASIK and LASEK, there is no risk of corneal flap complications with PRK laser eye surgery.
Am I Suitable for PRK Laser Eye Surgery?
PRK laser eye surgery is best suited for patients who have chronically dry eyes or thin corneas. Patients are required to take an eye exam to accurately ensure their suitability for PRK laser eye surgery. The eye exam includes an evaluation of the moistness in your eye, corneal curvature, the size of your pupils, and corneal thickness.
PRK is the predecessor of LASIK and LASEK, the most popular laser eye surgery treatments today. Although all three of these surgeries are safe and effective, and with high rates of patient satisfaction, at Optegra we are committed to providing our customers with the most innovative surgery techniques.
