» LASIK surgery in laser eye surgery
LASIK (laser-assisted in situ keratomileusis) is the most commonly performed refractive surgery procedure.
Both nearsighted and farsighted people can benefit from the LASIK procedure. With nearsighted people, the goal is
to flatten the too-steep cornea; with farsighted people, a steeper cornea is desired. Also, excimer lasers can correct
astigmatism, by smoothing an irregular cornea into a more normal shape. In 1991 a Greek surgeon, Ionas Pallikaris was
the first to use an instrument called a microkerarome to create a thin, circular flap in the cornea. After this was done he
folded the flap back out of the way, then removed some corneal tissue underneath using an excimer laser. The flap was then
laid back in place, covering the area where the corneal tissue was removed. The word "keratomileusis" was created by the
contraction of two Greek words and means "cornea reshaping"; "In situ" means "on the spot". In this way LASIK stands for
laser-assisted on the spot cornea reshaping. The method was further improved in Houston, New Orleans, Bogotá and Saudi Arabia.
Nowadays, LASIK is the most popular and most effective refractive surgery procedure.
