In Ultrasound mode, in addition to the irrigation and aspiration parameters described
in the previous section, it is possible to adjust the ultrasound mode and emission
level.
Ultrasound can be emitted in Continuous, Pulsed modes (with three duty cycle
levels, called "STD,"Cold"and "Ice cold "), Single Burst, Multiple Burst, Continuous
Burst.
If, for aspiration, the peristaltic pump is used, it is possible to select the "Autolimit"
mode that limits the power output to a maximum of 50 microns in case of occlusion,
thus decreasing the probability of corneal damage.
The "HD Pulse" mode, also available with peristaltic pump, automatically changes
the duty cycle in pulsed mode according to the occlusion state of the tip, in order to
minimize the time of emulsification of the cataract, while keeping low the
ultrasound energy issued.
