Variable Spot Scanning or VSS is an exclusive VISX laser technology that assists our surgeon in the development of your personalized laser vision experience.

VSS allows for a larger treatment area, and therefore offers the surgeon a greater degree of flexibility in the creation of your personalized correction procedure when pupil size may be an issue.

Our VISX Star S4 Excimer Laser utilizes the VSS technology in creating a blend zone in nearsighted (myopic) patients receiving more than a diopter of vision correction. The advantage of this technology is that it adjusts the beam size according to the treatment being performed, minimizing the amount of tissue removed. This allows for faster treatment.
