LASIK, for Better health Eye Vision

LASIK emerged from the development of various surgical techniques refractive. Essentially there are 2 stage LASIK process. First, make small openings on the thin corneas, and the second phase is to redesign the cornea by removing a tissue in the cornea using the laser. Aperture cornea and then closed again, the basic of LASIK create openings in the cornea begins in the 1950s, when finding microceratome, a mechanical metal knife that used to open the cornea. For many years, microceratome continue to be until now, the process of corneas to be safe and comfortable.

The discovery of a seconds technology for LASIK appear in 1980 which found that ultraviolet laser can fetch a network of right without damaging the surrounding network. Two years later, and the potential function of the laser in this field is announced surgeries. Cornea is an important role in the LASIK because the cornea holding almost entirely on the strength of refraction eye, the eye where the source of strength that comes from the other lens is crystal clear that the natural eye. Therefore, modify the shape of the cornea also change the status of refraction in the eye. This is the basic principle behind the operation and LASIK surgery on the cornea refractive.

To treat dim far (myopia), the central cornea shaped to reduce the ability of refraction cornea, to treat farsighted (hyperopia), sharpened the cornea to improve the ability of illumination. To treat eye aberration as the view that it is not clear (astigmatism), curvature of cornea that is 90 degrees from the standard created equal and balance.
