LASIK (Laser In Situ Keratomileusis) is the most advanced of all
the refractive surgical procedures and is used to treat most refractive
errors. First performed for vision correction in 1991, it combines
the excimer laser with the first part of another procedure called
Automated Lamellar Keratectomy, commonly referred to as ALK. Because
of the excimer laser, this procedure has a high degree of predictability.
In the first part of the procedure, a thin flap of corneal tissue
is created and moved over as though on a hinge. Next, the computer
driven excimer laser is used to reshape the underlying tissue. Finally,
the surface layer is repositioned.
LASIK takes about 15 minutes to complete and is painless. With LASIK,
both eyes are typically treated in the same session. Vision usually
recovers quickly and there is generally minimal discomfort following
the procedure. Most patients return to a normal lifestyle within
a day.
