The Right Laser System For More Patients
The STAR S4 IR™ Excimer Laser System is designed to bring Advanced CustomVue™ laser vision correction to life. Featuring VSS Refractive™ technology (Variable Spot Scanning) and VRR™ (Variable Repetition Rate) pulse-packing algorithm, both proprietary to AMO, the STAR S4 IR™ Excimer Laser reduces thermal effects on the cornea, allowing you to perform the Advanced CustomVue procedure quickly and effectively, while maximizing patient safety.
Using the STAR S4 IR™ Excimer Laser System, surgeons can deliver the broadest range of wavefront-guided laser vision correction treatments to patients. In fact, more than 94 percent of eligible candidates in the U.S., and more than 99.75 percent outside the U.S., may potentially benefit from the Advanced CustomVue procedure.*
· Delivers benefits of Iris Registration (IR).
· Conserves tissue by optimizing treatment times and minimizing thermal effects on the cornea.
· Minimizes additional time for wavefront-guided custom treatment over conventional treatment.
· Eliminates the need for dilation; laser tracks on the natural pupil.
· Maximizes practice efficiency and workflow through ease of use and ergonomics.
· Adjusts for intra-patient (XYZ) movement with ActiveTrak™ to further improve treatment accuracy.
Optimal results require precise alignment of the laser treatment. By linking diagnostic wavefront information with the treatment itself during the Advanced CustomVue procedure, IR provides a much higher level of alignment accuracy and precision, giving the surgeon confidence that the treatment will be placed in the correct location.
During treatment delivery, IR:
Finds and unwraps the iris in preoperative and operative images.
Selects prominent reference points.
Applies a set of sophisticated algorithms to find multiple matching reference points for each iris.
Calculates the ablation torsional angle from multiple matching reference points, and adjusts the treatment positioning prior to ablation.
Automatically checks the solution quality to help prevent false matches.
Optimal Outcomes With Iris Registration (IR)
A patient's pupil center will move relative to the outer iris boundary in different environments. To minimize the impact of this movement, IR:
Records the outer iris boundary at the WaveScan and laser.
References the WaveScan pupil center to the outer iris boundary.
Records the pupil center relative to the outer iris boundary and compares it under the laser to the WaveScan reading.
Centers the laser ablation over the WaveScan pupil center.
