The VISX STAR platform's heritage of dependability and performance is well known. The STAR S4 from VISX has taken that reputation to an even higher level. Integrating data collected by the WaveScan WaveFront System, the STAR S4 utilizes these exclusive VISX technologies to deliver precision custom ablations.

• Variable Spot Scanning (VSS): Variable beam sizes from as small as 0.65 mm up to 6.5 mm scanned over the treatment area, conserving tissue and optimizing treatment times.

• Variable Repetition Rate (VRR): VRR delivers treatment at varying repetition rates, optimizing treatment time.

• ActiveTrak 3-D Active Eye Tracking: Captures all 3 dimensions of intra-operative eye movements—no dilation required.

• ActiveTrak Automatic Centering: Locates, and then automatically sets the treatment center to the ­center of the pupil.
