LASIK is an acronym of "Laser-Assisted In situ Keratomileusis," a surgical procedure used for correcting vision. It is popular for its relative painlessness and shorter recovery time compared to other procedures. LASIK eye treatment involves altering the shape of the cornea (the clear part of your eye that focuses light and lets you see) using a device called a microkeratome in conjunction with a laser. It is effective whether you are nearsighted, farsighted, or astigmatic.

The Procedure

A good examination before the operation is necessary. Your doctor may prescribe medicines or procedures to better prepare you for the surgery. The operation itself is done with you awake and mobile, but the surgeon may opt for a sedative. It is a two-step procedure, the first one creating a flap of tissue that is folded up from your cornea, and the second using an excimer laser to remodel the cornea. A special variant called wavefront laser eye surgery uses a high-power laser guided by a computer to try to achieve an optically perfect eye. Results are usually immediate, taking a day at most to manifest.

Complications and Prevention

As with any surgery, there is a low risk of complications, among them dry eyes, over or undercorrection, haloes, double vision, and growths under the flap. Good care before, during, and after LASIK eye treatment is important in preventing these.

Choosing a good LASIK eye surgeon is vital to achieving a good result. Aside from basic competence, LASIK eye surgeons should be well-versed in a variety of procedures. A fair rule of thumb is that good credentials often make for a safer choice.

Summary

Just remember, while LASIK eye surgery can give you excellent vision results for minimal pain and inconvenience, it should still be treated with the respect and care due any surgical procedure. With the right care, clarity of vision is just a short operation away.
