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 modified the standard “square” wave pulse, by
increasing the amplitude of the first millisecond 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.
