VISX Variable
Spot Scanning (VSS)
Provides
Flexibility In More Personalized
Laser Vision Correction
Variable Spot Scanning (VSS)*
is an exclusive VISX
laser technology that
allows for a larger
treatment area. This
offers the physician
greater flexibility in
developing a more
personalized laser
vision procedure when
pupil size may be a
consideration.
Unlike other scanning
systems, VSS provides
variable size and shape
beams with scanning
capabilities. This gives
the device a wide range
of indications, offering
more flexibility in
personalizing refractive
treatments for myopic,
astigmatic, and
hyperopic patients.

How VSS
Technology Works
|
 |
|
Seven-beam array:
This exclusive VISX
technology produces an
even and homogenous
energy profile, using a
sophisticated array of
seven beams for a
uniquely consistent,
smooth treatment that no
other laser system can
match.
Variable-size beams:
Unlike fixed-spot
lasers, beam diameters
range in size from in
size from 0.65 mm to 6.5
mm to perform even the
most intricate
procedures.
Variable-shape beams:
Beams are shaped to
create spherical,
cylindrical, or
elliptical removals
depending on treatment
needs.
Scanning capabilities:
Beams scan across the
cornea for flexible
treatment modalities.
And, unlike fixed-beam
scanning lasers, the VSS
seven-beam technology
removes more tissue per
pulse , enabling
procedures to be
completed quickly and
efficiently with less
total tissue removal.
CAP Customized
Treatments: Due
to the various sizes and
shapes of beams
available, laser vision
correction can be
customized for those of
you who need specialized
care due to irregular
astigmatism or other
difficult problems to
treat.
What VSS Does for You:
Variable Spot Scanning
makes it possible for
your treatment to be
shorter in time. This
adds to your comfort. In
addition, VSS takes off
less tissue per given
prescription than other
lasers. This is
important, especially
for those with thin
corneas or high
prescriptions. It is
important that the
cornea be of sufficient
thickness after the
procedure for stability.
The VISX Star S4
Variable Spot Scanning
Laser lets us know
before the procedure how
much tissue will be
taken off so that we can
stay well within safe
limits. It is also more
tissue sparing than
fixed spot lasers.
Variable Spot Scanning
makes a very smooth
treated surface on the
eye.
