Laser In-Situ Keratomileusis... Image

In LASIK surgery, the eye is held open with a speculum, and a suction ring is attached to the eyeball (A). A microkeratome is used to shave the protective flap off the top of the eye (B), which is then pulled back (C). A computer-controlled laser is used to reshape the cornea (D), and the protective flap is replaced (E). (Illustration by GGS Inc.)
