LASIK eye surgery: Step-by-Step

Laser assisted in-situ keratomileusis (LASIK) is an operation that involves cutting a flap from the cornea of the eye. The interior of the cornea is then shaped with an ultraviolet excimer laser and the flap replaced. Using the flap greatly assists the healing process and is the reason when LASIK is so popular (as compared to PRK or LASEK eye procedures). The main requirements for LASIK candidacy are reasonable prescription (-0.75 to -11 diopter nearsightedness, 0.75 to 4 diopter farsightedness, and 0.75 to 4 astigmatism), a pupil diameter that is smaller than 8.5 mm, and a corneal thickness greater than 500 microns. (Requirements may vary due to prescription and specific eyes.)

At this point, I felt something rotating on my eye (the microkeratome). No pain, no irritating, I just felt the movement. Then the world started to fade back and the circle of light with the red dot was back – except now it had both a crisp and hazy quality to it.
