PRK Eye Surgery (Photorefractive Keratectomy)
Photorefractive Keratectomy is an elective, outpatient laser vision correction procedure to improve vision and reduce or eliminate the need for eyeglasses or contact lenses. In the PRK laser vision correction procedure, our surgeon utilizes the excimer laser to reshape the curvature of the eye for patients with nearsightedness, farsightedness and astigmatism.
Wavefront Technology
With Custom Laser Vision Correction, Your surgeon is able to focus on the quantity as well as the quality of your vision. Many patients who have had Custom Laser Vision Correction are reporting the ability to see clearer than ever before. Custom Laser Vision Correction uses a Wavefront Analyzer to measure the way light travels through your eye. The Wavefront Analyzer creates a customized 3-D map of your eye that looks at your entire optical system. This map provides information about the unique visual characteristics of your eye which adds an additional level of data about your vision, enabling your refractive surgeon to further customize your vision correction. This map that is created is then used to guide the laser during your laser vision correction procedure for optimal results.
Better Quality VisionClinical studies have shown that Custom Laser Vision Correction may improve not only what you see but also how well you see it. In the past, all vision was measured using a standard vision chart. If you could see the letters, the eye doctor would use that measurement for how well you could see. Several types of visual imperfections, referred to as lower- and higher-order aberrations, exist within the eye and may affect your vision (the amount of these aberrations vary from person to person).

Previously, only lower-order aberrations (such as nearsightedness, farsightedness and astigmatism) could be measured and treated. Higher-order aberrations may also have a significant impact on vision and have been linked to glare and halos. Now Custom Laser Vision Correction may help to further customize your treatment of these higher-order aberrations that, in the past, could not be adequately treated with glasses, contacts or conventional Laser Vision Correction treatments.
Why PRK?
In general, PRK is the most common form of laser resurfacing in patients with anatomy not suitable for LASIK. It is also the most common method by which an enhancement is performed if a patient has a history of prior laser vision correction. General benefits of PRK:
