Lehmann Eye Center continues to hold the lead in ophthalmology with the delivery of the most advanced eye tracking technology available with the VISX Star s4 ActiveTrak Excimer Laser System.
Variable beam technology allows Lehmann Eye Center doctors to treat patients with different laser beam sizes and shapes depending on the patient's visual needs. The Star S4 ActiveTrak laser system combines the VISX variable beam shaping with VISX scanning technology when it is programmed to specifically treat the patient's eye.
The VISX Star systems have been used in more than two million procedures worldwide. This newest generation laser system incorporates the latest active eye-tracking system in addition to many other advancements to help our surgeons deliver the best possible treatment. VISX patented variable beam technology, allows the fastest treatment time and provides the future platform for custom ablations.
Designed to provide better laser vision correction, the ActiveTrak eye tracker is a new 3D eye-tracking technology. With ActiveTrak, the laser detects and compensates for small eye movements by guiding the laser beam to keep it centered precisely over the treatment area. ActiveTrak continuously repositions the laser beam throughout the procedure for greater accuracy. ActiveTrak realigns itself between each laser pulse insuring pinpoint accuracy. The eye tracker adds a new level of precision, comfort, and safety not previously available.
This new technology makes older eye trackers — which require dilation — virtually obsolete. Compared to other trackers, ActiveTrak requires no pupil dilation, which allows the surgeon to center the laser beam more accurately. Not having to be dilated eliminates the inconvenience and discomfort of dilation, and adds to patient confidence with the safety of the procedure. Because vision is not hindered by dilation, most patients are able to appreciate the improvement in their vision immediately after being treated.
