A Flapless LASIK Alternative
Advanced Surface Ablation (ASA), also known as Photorefractive Keratectomy (PRK), is a bladeless LASIK alternative that does not use any sharp instruments and does not create a corneal flap typical of traditional LASIK.
PRK is effective in patients with thinner corneas, minor corneal irregularities, or for patients with specific occupations/hobbies such as contact sports. It has been shown to provide results that are just as good LASIK.
