nearsightedness, the cornea must be made flatter. This is
accomplished by removing tissue from the center of the cornea
To treat farsightedness, the central cornea must be made steeper.
This is accomplished by directing the laser beam to remove tissue
from around this area.
astigmatism, the cornea must be made more spherical. By changing the
pattern of the beam, more tissue is removed in one direction than
The CustomVue Map is derived from technology first developed to correct
distortions of light waves from space. This allows researchers to accurately
view images of stars and planets.
The CustomVue Map uses the same technology to measure light waves as they
travel through your eye.
Without a tracking device, laser vision correction requires patients to hold
their eyes perfectly still during the process. However, even a "still" eye
makes minute, involuntary movements, including slight movement with each
breath. The 3D ActiveTrak follows the most specific movement
instantaneously, repositioning the laser automatically to ensure laser
In the early 1980's, VISX,
INC. developed the first Eximer laser designed to improve the precision and
predictability of altering the shape of the cornea over the previous
technique (RK) that used incisions. We use the newest generation VISX STAR
Eximer Laser System that incorporates variable beam technology with an
active eye tracking system.
The ActiveTrak™ continuously positions the laser beam precisely on the eye
throughout the procedure. It is the only 3D tracker that is capable of
tracking all eye movements (side-to-side and up and down) and there is no
need to dilate the pupil.
This assures accurate placement of the beam, helps our patients feel more at
ease during treatment and allows patients to appreciate their improved
vision much quicker. The VISX STARS's variable beam technology provides
faster treatment times, a smoother surface, and allows the surgeon to shape
the beam to meet each patients's individual correction need.
correction has revolutionized vision care.
Common vision problems that cause one to be nearsighted,
farsighted and/or suffer from astigmatism, can actually be treated.
Scanning (VSS) is an exclusive VISX® laser technology that
allows for a larger treatment area.
This offers us greater flexibilty in developing a more personalized
laser vision procedure, when pupil size may be a consideration
