This type of laser vision correction does not
require any corneal incision at all. A mild alcohol solution is
placed on the corneal to loosen the top layer of tissue. Only
the most superficial layer of the cornea is gently brushed
aside. This thin flap is then replaced after the laser reshaping
is complete. Less tissue is removed than with traditional Lasik.
Patients with thin corneas, or patients who have had previous
vision correction such as RK, can possibly now have laser vision
correction safely performed. Healing may be faster than with
To treat nearsightedness, the cornea is made flatter by
removing tissue from the center of the cornea.
To treat farsightedness, the flat cornea is made steeper
by removing peripheral tissue in a ring shape on the outer edges
of the cornea. This steepens the central visual part of the
To treat astigmatism, the cornea is made less oval
shaped. Astigmatism means that the eye has an oval or football
shape. The laser reduces the oval shape making the focusing
ability clear in all directions. Astigmatism can be treated at
the same time as nearsightedness and farsightedness.
Patients generally have had marvelous results with LASEK eye
surgery. The benefits of LASEK eye surgery include a laser eye
surgery option for patients who ay not be good candidates for
