There are two methods of laser correction - PRK and LASIK.

PRK In PRK, the laser is present to vaporize or remove portions of tissue on the surface of the cornea. Areas of tissue which are ablated cause the cornea to flatten in those same areas, reducing the prescription required to see clearly.

PRK is performed under local anesthesia. The procedure itself takes only a few minutes. Then, regular follow-up visits are essential to monitor your progress. There are some restrictionc, patients should avoid visiting swimming pools, alcohol, hormonal medications, taking sun-baths.

The PRK procedure

LASIK Lasik stands for Laser Assisted In Situ Keratomileusis and is the most common type of laser vision correction procedure. Lasik represents the combination of two procedures: making a corneal flap and sculpting the cornea under the flap with a laser. In the first step, the surgeon uses the instrument called a microkeratome to make a hinged corneal flap. The flap is is folded back exposing the bed of the cornea. In the second step, a cool laser beam sculpts the curvature of the exposed corneal by evaporating tissue.
