The most important aspect of the excimer
laser is that it is remarkably precise. It is able to remove
0.25 microns of tissue in a single pulse; that is, 1/200th the
thickness of a human hair, 1/40th of a human cell, 1/28th of a
red blood cell, or 39 millionths of an inch in 12 billionths
of a second!
There are two procedures which use this
unparalleled precision by applying computer controlled pulses
of laser light to reshape the eye to correct
nearsightedness,astigmatism and farsightedness; PRK and LASIK.
PRK, or photorefractive keratectomy, is a
refractive surgery technique which reshapes the surface of the
cornea, while LASIK, or laser in situ keratomileusis, reshapes
the inner layers of the cornea. Lasik works well for even
moderate & high degrees of myopia and is the procedure of
choice today.
LASIK offers faster and more comfortable
visual recovery, more accurate results and better corneal
transperancy as compared to PRK.
It is this advantage of healing combined with
the precision of the excimer laser that has made LASIK the
overwhelming procedure of choice at LASER VISION and at other
dedicated centers performing large numbers of procedures.
