Variable Spot Tanning
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 1.0 mm to 6.0mm to perform even the most intricate procedure. |
|
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. |
*The VISX laser utilizes the VSS technology in creating a blend zone in myopic patients receiving-1.0 diopter of vision correction.
