The WHITESTAR ICE Technology was the next advance in micropulse phacoemulsification
technology. This technology combined modulated ultrasonic power (pulse shaping) with
vacuum control through the use 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”. The technology then set the
remaining part of the on time to the standard power setting. This process repeats for each on
time pulse. This results in increased control and efficiency in phacoemulsification.
Occlusion Mode Phaco
The Occlusion mode phaco regulates the vacuum rise time following an occlusion of the
phaco tip, without limiting the choice of aspiration rate through an unoccluded tip. To
independently control the aspiration rate and the vacuum rise time, you can have a different
aspiration rate when the tip occludes than when the tip is unoccluded.
The Occlusion mode phaco also regulates the ultrasound power modulation. You can
program the power modulation of the phaco handpiece (continuous, pulse, burst) to
automatically change when the phaco tip changes from an unoccluded condition to an
occluded condition.
The FUSION mode allows the user to access the settings and variables for both CASE and
Occlusion mode phaco. The CASE and Occlusion mode phaco can work together or
independently.
