The title itself says how this eye surgery is performed. A laser is used to re-shape the cornea to restore near normal vision.

Either a laser or special blade is used to cut a flap in the cornea. Having exposed the cornea a special laser is used to reshape and thus help restore normal vision.

After the procedure the flap is then replaced back to finish the laser eye surgery procedure. Though there are so many laser eye surgery procedures available nowadays allowing people to choose a particular surgery procedure, still but this is the most common and general way of performing laser eye surgery.
