PRK (photorefractive keratectomy) is a form of laser eye surgery used to improve vision and to reduce dependance on glasses or contact lenses. Here at Center for Advanced Eye Care, we use the very latest technology in the Alcon Wavelight, the fatest laser in existence. It takes a fraction of the time to complete the surgery compared with older technologies. This method, known as wavefront-guided PRK or advanced surface ablation, improves accuracy while maintaining the natural shape of the cornea. It provides the patient with the very best optical outcome.
