If people don't want to wear glasses or lenses, they may choose to get laser surgeries. Of which, LASIK, the abbreviation of Laser-assisted in Situ Keratomileusis, is one of the most popular surgeries received by over one million people each year in US. In the whole procedure, an excimer laser will be used as scalpel to remove something extra in the cornea.
However, lasik is not suitable for all people and receivers should first make an eye exam and consult with their eye doctors.

At the same time, people should tell their health history to their eye doctors, like whether or not allergic to certain medications. Anyway, the eye doctor will tell people what kind of risks and benefits will be involved in the surgery. This can help people have a good consideration.
Receivers will feel no obvious pain, for some numbing drops will be used in the surgery. As its name indicates, an excier laser will be used to make a cut on the surface of the cornea and the flap will pulled back, so as to let the laser in. the laser will be used to remove the extra tissues in cornea. During the procedure, receivers are required to stare at the special devices that will generate special lights. When a ticking is heard, the surgery starts. After that, the flap will be positioned back.
Comparatively speaking, laser has more advantages than traditional blade, which is less accurate and precise. In addition, laser can make cornea more flat and recover quickly than blade. After the surgery, patients should wear certain eye shield, which can ensure wearers will not rub their eyes because of itchy before the flap is healed.
