Excimer Laser works by altering the shape of the cornea so that the newly shaped cornea can focus light rays directly on the retina, producing clear vision. When successful, refractive surgery can dramatically reduce or eliminate the patient's need for glasses or contact lenses.
PRK (photo refractive keratectomy) is a computer-assisted process that uses an excimer laser to correct your refractive error. During the procedure, the cornea is reshaped using the energy from the light emitted by the laser. For mild to moderate amounts of myopia, the vast majority of patients achieve 20/40 or better vision.
The most common complaint after undergoing PRK is experiencing a hazy sensation and seeing haloes when looking at lights. For some patients, it may take weeks to months to achieve best vision after PRK.
If you've decided that you would like to consider refractive surgery, the first step is to get a complete eye examination and discuss your desire with the doctor. Besides determining your refractive error, your doctor will also check that there is no disease or corneal irregularity present that might complicate a refractive surgery procedure. Questions about lifestyle and occupation will also come into play.
