LASIK (Laser in situ Keratomleusis) is a vision correction method that is performed with the help of an Excimer laser. This laser reshapes the cornea and also heals farsightedness, nearsightedness and even astigmatism. The doctor conducting LASIK first uses a femtosecond laser for precision for few seconds in order to create a thin flap of cornea. The Excimer laser comes into picture wherein it is already pre-programmed according to your exact correction. This laser applies cool UV light rapidly that removes minute tissues from the inner part of cornea. The short laser modulations correct the cornea curvature so that images get focused clearly on the retina. The created flap is than preened back into its original place where it quickly fastens back in four to five minutes, rebuilding a smooth intact surface
