Active Trak is a technology exclusively available on the VISX S4 IR excimer laser, a component of the iLASIK system. This technology lets the doctor track eye movements in all three dimensions, so that the laser beam is always correctly centered on the eye. This allows patients to achieve optimal results.
The human eye is moving constantly. An accurate laser vision treatment depends on a system the can take this into account. When laser treatments are not delivered to the right area, patients may suffer from blurry vision and other visual distortions. That is why we use the VISX STAR S4 IR with Active Trak technology. This unique tracking system allows our laser to detect and compensate for small eye movement in all 3 dimensions. Consequently, the laser beam is perfectly delivered to the target area despite any patient movement. This occurs between each pulse, ensuring pinpoint accuracy during the entire treatment. |
