Allegretto Wave With PerfectPulse Technology

The ALLEGRETTO WAVE’s proprietary PerfectPulse Technology incorporates several proprietary safety features that help to further protect a patient's vision:

• Smart Energy Control: Each laser pulse is checked three times before it is delivered to the cornea.  If laser pulse energy is not at the desired level when it reaches these checkpoints, the system will automatically adjust before delivering the next pulse. 
• Fast Eye-tracking: Three independent infrared sources follow the eye's movements 200 times per second—once for every laser pulse administered. The system reacts in just four to six milliseconds (ms) if the eye shifts even a fraction of a millimeter. This virtually eliminates the chance of errant laser pulses that could impact the cornea.
• Wavefront-Optimization: Automatically determines each individual's unique pre-operative corneal shape and provides a treatment that not only corrects nearsightedness and farsightedness, but also maintains the cornea's natural curve following treatment. As a result, studies have found the ALLEGRETTO WAVE to be one of the first lasers in which patients reported a reduction in postoperative glare compared to their pre-operative vision.  
• Non-Overlapping Pulses: The laser's internal computer monitors the location of each pulse applied to the eye and makes sure that if a location needs additional pulses, it is treated no more than once every fifth laser pulse. This reduces the chances of any kind of heating effects occurring in the eye.

The ALLEGRETTO WAVE has been successfully used since the late 90s in Europe, where it has been the leader in international sales for the past three years.  In the U.S., it was the first new laser platform to be cleared by the Food and Drug Administration (FDA) in nearly five years, and that clearance was for the highest-ever ranges of nearsightedness and farsightedness.
