LASIK (Laser-Assisted in Situ Keratomileusis), is a type of refractive laser eye surgery performed by ophthalmologists for correcting myopia, hyperopia, and astigmatism in order to eliminate or reduce the need for glasses and/or contact lenses.

 It's not indicated for people who:

• are aged less than 18 years.

• have not had stable vision for at least one year.

• have any other diseases of the cornea.

In traditional LASIK surgery, a round, thin flap is cut from the cornea’s surface in a way that leaves part of it still connected. It’s gently folded back to expose the stroma, the next level of tissue. Then an excimer laser is directed precisely onto the stroma to vaporize tiny areas, thus removing irregularities that are causing defective vision. The little flap is then replaced and the eye heals itself in a day or two.

The entire LASIK process takes about 20 minutes to do both eyes. Most patients experience little pain or discomfort after LASIK surgery but may have some minor swelling of the eye.
