If LASIK is not an option for you, photorefractive keratectomy/advanced surface ablation (PRK/ASA) may be an option for vision correction. Using an Excimer laser, your doctor will remove the epithelium – the protective surface layer – of your cornea. Then, using cool laser technology, your doctor reshapes your cornea. A soft contact lens protects your eye as it heals for about a week, with full recovery in two or three weeks. You may experience mild to marked discomfort and blurry vision at first. You’ll experience most of your vision improvement in the first month, with some additional improvement over the course of a year. PRK/ASA results do take longer than LASIK thanks to slower healing.
