WHITESTAR ICE Technology (Pulse Shaping)
The WHITESTAR ICE Technology was the next micro-pulse advance in phacoemulsification
technology, which combined modulated ultrasonic power (pulse shaping) with vacuum
control through the application of the Chamber Stabilization Environment (CASE).
This pulse shaping technology modifies the standard square wave pulse, by increasing the
amplitude of the two milliseconds of the on time “kick”, and then setting the remaining part
of the on time to the standard power setting. This is repeated for each on time period,
resulting in increased control and efficiency in phacoemulsification.
