The preliminary incision is made using a microkeratome or a femtosecond laser and also a flap of the cornea at the designated place is reduced. In doing so, the flap is folded back to reveal the stroma, which is the mid-section of the cornea. Next an excimer laser is used to realign the stroma.
Throughout the process, the setting of the eye is tracked by a computer system, at speeds of 4,000 times per second.
