LASIK (Laser-Assisted In-situ Keratomileusis) is a surgical method to correct certain vision disorders. This surgery is used to reduce or eliminate the need for eyeglasses or corrective lenses. The LASIK surgery is advised to a person in case when other treatments like eye drops, eye exercises, etc. do not prove to be effective on fixing eye problems. In this surgery, cornea is given the correct shape with the help of laser. The main aim of this surgery is to focus the light rays exactly on the retina neither beyond nor short of retina so that a clearer and sharp vision can be achieved. To correct the shape of cornea the surgeon remove some tissues from the middle layer of cornea. To reach middle layer, a flap is made in cornea using microkeratome blade or laser. This flap is laid back after the surgery
