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.

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.
*The VISX laser utilizes the VSS technology in creating a blend zone in myopic patients receiving -1.0 diopter of vision correction.
