LASIK is a technique were the doctor use a mechanical device called microkeratome or femtosecond laser in order to create a flap with a hinge.
LASIK surgery is a procedure that treats the refractive errors such as: Myopia (Nearsighted), Presbyopia (Farsightedness) and Astigmatism. But no all kind of astigmatism can be correct with LASIK eye surgery, considering that astigmatism can be manifested on the surface of your cornea and also on the natural lens inside your eye.
Traditional LASIK surgery is a very successful technique. Recovering time and result are immediately.
In this video we can see the doctor using a device called microkeratome. This particular device is used, in order to create a flap with a hinge on the cornea, and as soon as the flap is ready, the flap can be flip in order to fire the Laser. The laser treats the cornea, base on an interpretation taken from the topographer and Laser machine program.
As soon as the Laser is done, the doctor reposition the flap back in place and the surgery is done.
The microkeratome work in a manner that a ring located on top of the cornea will suck the eye ball, exposing the cornea to be cut by a mechanic blade. This process take only a few seconds, but on these seconds the patient experience some discomfort no pain, and also the patient lose the vision for a few seconds while the suction is active.
