Horizon Advantage - Laser

Horizon Laser Vision Center uses the most advanced VISX Star S4™ Excimer Laser, the CustomVue, for both LASIK and PRK. This laser utilizes the latest technology currently available, which translates into greater accuracy of treatments, safety and improved visual outcomes.

The VISX Star S4™ Excimer Laser System is a computer-assisted surgeon-controlled device that includes WaveScan® and ActiveTrak® devices combined with Variable Spot Scanning (VSS®) technology in addition to excimer lasers.

Excimer lasers are cool concentrated beams of ultraviolet light that safely, painlessly evaporate microscopic layers of the cornea leaving the underlying tissue virtually untouched.

The WaveScan uses light wave technology to identify and measure imperfections in an individual's eye 25 times more accurately than standard methods used for glasses and contact lenses. These measurements are used to individually customize laser vision correction. The WaveScan produces a WavePrint Map®, which is a visual representation of how a patient's entire optical system processes light. This map is much like a fingerprint - no two are alike. It allows for a more precise and detailed analysis of a patient's vision and is used by the ophthalmologist to ensure optimal treatment results.

ActiveTrak™ 3D Eye Tracker follows the tiny motions of your eye instantaneously and automatically, in all three dimensions, continually repositioning the laser to ensure accuracy. Without a tracking device, laser vision correction requires patients to hold their eyes as still as possible during the procedure. However, even a 'still' eye makes minute, involuntary movements - including moving slightly with each breath. With 3D ActiveTrak, you can relax during your laser vision correction, knowing the procedure will be delivered with precision and accuracy.

Variable Spot Scanning* (VSS™) is an exclusive VISX laser technology that allows for a larger treatment area. This offers the ophthalmologist greater flexibility in developing a more personalized laser vision procedure. It adjusts the laser beam size according to the treatment, minimizing corneal tissue removal. This also allows for quicker treatment times that are typically between 10 to 40 seconds. Variable Spot Scanning technology adds a blend zone that allows the treatment on the cornea to be extended to 8 mm which may help reduce the risk of night vision symptoms in certain patients.

The VISX laser has been used to perform over 5 million procedures globally. Visit the VISX web site to learn more about this advanced technology.
