Q. How is LASIK surgery performed?


LASIK is laser vision correction procedure utilizing a laser called EXCIMER laser. These are high energy beam which transfers the energy to corneal tissues. The surgery is done through computer-controlled laser for high accuracy and precision and the energy so transferred to the corneal tissue causes corneal reshaping by vaporizing a small quantity of tissues.

The surgery takes place in two steps. In the FIRST step, a very thin and hinged corneal flap is formed with the help of a laser ( femtolasik or blade free lasik ) or automated microkeratome ( blade lasik ). In the SECOND step, the flap is pulled to expose the underlying corneal tissue and the excimer laser is used to reshape the cornea by removing a small amount of corneal tissue. After reshaping the cornea, the flap is then repositioned on the cornea.
