With LASIK, the middle portion of the
cornea is treated by first using a
machine called a microkeratome to cut
and lift the top surface of the cornea.
The laser is then used to reshape the
exposed corneal surface.
With W-ASA, or wavefront advanced
surface ablation, the laser light only
is used to reshape the front surface of
the eye, without cutting the top surface
of the eye. Both procedures can be used
to correct near sightedness,
farsightedness, and astigmatism. Surface
ablation has been performed in this
country for about fifteen years, and
LASIK for about eight years. Dr. Palumbo
became a Summit Technology Visionary
when he traveled internationally in 1990
to initiate his research with Laser
Vision Correction. |
