More and more people choose to do eye surgery to correct eyes because they are bored with wearing eyeglasses and contacts. However, the categories of laser eye surgery vary greatly among each other and they actually fit different eye situations. So if you really opt to do eye surgery, you are recommended to do some studies on laser eye surgery.

LASIK, which is short for laser-assisted in situ keratomileusis, is considered to be the most common and popular kind of laser eye surgery and it is effective to correct the situations like myopia, hyperopia and astigmatism. Before your doctor is ready to do the surgery for you, they will request you to take off your contacts for a couple of weeks. Only in that way they can measure the amounts of corneal tissue to be removed in each eye during the surgery. The procedures of LASIK include flapping and remodeling process of corneal tissue. During the flapping procedure, you are required to keep your eyes wide open to let your surgeon use a metal blade to create a flap of corneal tissue. Then the surgeon will reach to the middle layer of cornea with the help of flap and do the cornea reshaping. Finally, the flap is repositioned and the surgery id done. However, you have to pay attention to lots of notice items after surgery. For example, you should use antibiotic and anti-inflammatory eye drop to prevent any eye infection. You should be away from strong lights to prevent any hurt to eyes again. So we can say both the surgery itself and healing process are important for a successful eye surgery.

PRK and LASEK, which mean photorefractive keratectomy and laser-assisted sub-epithelial keratectomy separately, are two revolutionary kinds of laser eye surgeries being completely different from LASIK. There is only one procedure during the both two operations, which is achieved by the way of ablation to vaporize a small part of tissue from the front eyes in order to reshape the cornea. As the corneal epithelium is regenerative and can be built for a short time, you do not have to worry about the discarding of corneal. The fact that the operations do not have the process of corneal cutting makes them to be well-known as no touch laser vision correction. These surgeries are characterized as no manual surgical instruments and only one excimer laser from the beginning to the end of the surgery.

Since you know the main categories of laser eye surgery and both their advantageous and disadvantageous, you can choose one that is most suitable for you. Good luck!
