Refractive laser surgery is a type of eye surgery which is used in order to recover the refractive state of your eyes. As a consequence you will no longer have to wear glasses or contact lenses as you will usually have a 20/20 vision. Refractive laser surgery is based on the remodeling of your eye cornea. In order to do so, different types of lasers are used to reshape your cornea. This method can help you to cure vission issues such as myopia, astigmatism or even hyperopia.Different technique of refractive laser surgery exist. The first one to have appeared was the PRK method (Photorefractive keratectomy) which removes thanks to a laser, microscopic bits of tissue from your cornea stroma. Meanwhile patients found this method rather uncomfortable and long to recover. LASIK then appeared which as opposed to PRK does not remove part of the tissue. Other techniques such as LASEK (similar to PRK) or EPI-LASIK exist but are not used as much.
