VISX STAR S4 Excimer Laser System
VISX is chosen by many doctors for their unparalleled research and development and commitment to technological advances. The VISX Star4 laser is famous for its dependability and performance and is used by thousands of doctors worldwide. Patients who choose LASIK with the STAR 4 will experience a distinct procedure that is completely custom tailored to match his or her vision needs.
The VISX STAR S4 Excimer Laser System and the WaveScan Wavefront System combine to create the CustomVue Procedure.
WaveScan technology captures unique imperfections in each individual’s vision that could not have been measured before. This new level of measurement provides 25-times more precision than measurements using standard methods for glasses and contact lenses. WaveScan technology produces a detailed map of the eye – much like a fingerprint, no two are alike and translates this information into a set of CustomVue treatment instructions for the laser. WaveScan transfers these digital treatment instructions to the laser, providing a new level of precision and accuracy.
Integrating data collected by the WaveScan WaveFront System, the STAR S4 utilizes these exclusive VISX technologies to deliver precision custom LASIK:
- 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.
With the CustomVue procedure, no two “prescriptions” are identical. This precise level of measurement and treatment can enable individuals to achieve the full potential of their vision.
