subject: How Lasik Eye Surgery Works [print this page] As one of the most commonly performed refractive procedures, LASIK eye surgery stands for laser-assisted in situ keratomileusis. There are several different benefits to this operation when compared to the alternatives, and recovery time tends to be quick and pain-free. But before deciding that this is the best option for you, be sure to talk to your surgeon for more information on your specific circumstances.
The Process
A thin, circular flap is created around the cornea. In some cases this part of the LASIK eye surgery is done with a microkeratome, a very precise surgical instrument, while other surgeons use lasers to make the same incision. Once the flap is folded back out of the way, the surgeon begins to remove some of the tissue in order to reshape the cornea. Once this process is complete, the cornea can focus light into the eyes better, making a person's vision clear and crisp. The final step is placing the flap back over the cornea.
Patients That Can Benefit
Nearsighted and farsighted people can both benefit from LASIK eye surgery. When the cornea is too steep, as in the case of a nearsighted person, the procedure works to flatten it out. On the other hand, the surgery creates a steeper cornea for a farsighted person. In some cases, even those with astigmatism can benefit as the cornea is smoothed over into a more normal shape.
Before anything happens, a doctor will meet with a patient and decide if he or she is a candidate for the operation. Once it is determined that this is beneficial, plans will be made and the surgeon will talk about how much ablation (reshaping) is required. Special equipment is used to map out the cornea to get a better idea of what needs to be done in order to get the best results. The doctor also talks to the patient about any health concerns that may be problematic when it comes to the operation.
Recovery
Once the LASIK eye surgery is over, a patient is sent home to get some rest. Someone else will bring and pick up the patient as driving will be impossible. Before being released, a person will often rest in the office. From there, the rest should continue at home. Even if a patient feels like going to work the next day, most surgeons recommend that he or she take at least a few days off to allow the body to recover.
Eyesight improvement happens for some right away, but many people also experience improvements over the next couple of days and weeks. While every person is different, patients can typically expect to get 20/20 vision once the recovery is complete.
