NEW ADVANCED LASIK TECHNOLOGIES

Eye Tracking and New
New advances in state of the art LASIK, that
everyone’s been waiting for… By combining
three advanced technologies, ophthalmic
surgeons have available a new refractive laser
system. Using a variable spot size or scanning
beam laser, combined with eye tracking, and
wavefront analysis, doctors are able to perform
highly accurate and smooth sculpting of the
cornea. These techniques provide the basis for
more accurate, precise and predictable vision
correction for a wider range of patients. In fact, in
many patients, vision can be corrected to better
Using a sophisticated computer and mapping
software, wavefront analysis essentially involves
projecting a grid pattern into the eye and analyz-
ing the integrity of its reflected image for areas of
displacement, distortion and incomplete or fuzzy
images. As the projected image moves through
the eye, it must pass through the cornea, the lens
of the eye and be reflected back off the retina.
Theoretically, if the reflection of the grid pattern
is returned exactly the same as the pattern sent,
and in the predicted position, all aspects of the
eyes refractive apparatus are functioning perfect-
ly. However, if there is an aberration affecting
refraction anywhere in the eyes refractive system,
it will show up in the reflected image.
Every small area of the reflected grid pattern is
analyzed. If areas are found where the pattern is
out of position, distorted, incomplete or fuzzy,
specific correction can be targeted to that corre-
sponding location on the surface of the cornea.
