Lasik eye surgery is a refractive surgical procedure that works wonders on the eyes of people suffering from nearsightedness, farsightedness, astigmatism and presbyopia. It reduces a person's complete dependency on glasses and contact lenses. The full form of Lasik is Laser-Assisted In Situ Keratomileusis and is a procedure that involves permanently changing the shape of the cornea, the clear covering of the front of the eye using an excimer laser.

How is Lasik surgery done?

The surgery should be done with great skill as it involves the most delicate part of human body. It is done with a knife called microkeratome and is used to cut a flap in the cornea. A hinge is done at one end of this flap and then the flap is folded back revealing the stroma, which is the middle section of the cornea. Instant pulses from a computer-controlled laser vaporize a portion of the stroma and the flap can be easily replaced.

How is Lasik advantageous over other surgical procedures?

Lasik eye surgery is quite advantageous over other surgery procedures because they often involve much less pain as an aftermath. Lasik unlike other eye surgeries also promise extremely good vision that can be achieved almost immediately or at least by the next day.
