VISX Star S4 IR Active Trak

VISX Star S4 IR Active Trak

This excimer laser system is the latest generation of VISX technology. It incorporates many new and exciting technology features:

  • The variable spot beam technology. This advancement allows the beam to range in size and shape so that the delivered energy is more custom to the patient's cornea.
  • 3D active track allows the laser to follow the tiny motions of your eye instantaneously and automatically in all three dimensions. 3D active track repositions the laser to insure accuracy and it does not require you to hold your eye still like other non-tracking lasers so that you can relax during the treatment.
  • VSS, variable spot scanning, is an exclusive VISX laser technology that allows a treatment area. This technology allows a blend zone that increases the total treatment zone by 51%. This can be very helpful in patients who have concerns about post surgical glare and halo.
  • Iris Registration (IR), the first FDA-approved, fully automated, non-contact method of alignment of the CustomVue treatment to the corneal site.
