The Visx Star 4 Laser is Equipped with Iris Registration and Wavefront Guided Technology, which vastly improves patients’ visual outcomes.
Exclusive to the VISX Star S4 laser, Iris Registration (IR) provides the most precise laser alignment accuracy to date, resulting in safer and more accurate surgical procedures, and even better outcomes.
Used only in combination with the Wavefront Guided treatment, IR is a fully automated, no-touch technology that allows us to create a “fingerprint” of your iris with microscopic detail and precision.
As part of your consultation, we use Wavescan diagnostics to look at the tissues (cornea, lens, and retina) that impact the way light moves through your eye. During your surgery, IR creates a very detailed image of your iris, making it possible to align our laser perfectly to your eye. Since no two irises are the same, IR also ensures that the correct prescription is matched to the correct eye and patient. No other technology offers this assurance.
Wavefront Guided Technology
Wavefront Guided technology allows for a complete, personalized treatment of the entire visual system. It was originally developed by NASA for the Hubble space telescope to help reduce the distortion one might see when viewing objects positioned in outer space, but today it has revolutionized the refractive surgery industry.
The WaveScan completed during your consultation identifies even the smallest visual imperfections and this data is loaded into the VISX laser. The laser can then use this data to treat your cornea, “customizing” your LASIK or PRK treatment to your exact visual needs.
Your Customized Scans
WaveScan is a personalized measurement of the entire visual system, including small imperfections and your unique prescription (including astigmatism).
The Orbscan produces an incredibly detailed topographical map of your eyes. This full-color map provides our surgeons with detailed information about your corneas’ precise characteristics, such as their elevations, inclinations, corneal thickness, and curvatures.
