Laser Surgery for the Eye
For many people, laser eye surgery can correct their vision so they no longer need glasses or contact lenses. Laser eye surgery reshapes the cornea, the clear front part of the eye and changes its focusing power. There are different types of laser eye surgery.

The surgeon folds back the flap, then removes some corneal tissue underneath using an excimer laser. The flap is then laid back in place, covering the area where the corneal tissue was removed.
With nearsighted people, the goal of LASIK is to flatten the too-steep cornea; with farsighted people, a steeper cornea is desired. LASIK can also correct astigmatism by smoothing an irregular cornea into a more normal shape.
If you are considering LASIK eye surgery, your first step is to choose a good LASIK surgeon who can evaluate whether LASIK is right for you. Your LASIK surgeon will examine your eyes to determine their health, what kind of vision correction you need, and how much laser ablation (corneal tissue removal) is required.
The doctor will also ask about any health conditions that may disqualify you altogether for LASIK. If you
