PHACO Submodes
There are four PHACO submodes. Within each submode, there are programmable
parameters for Unoccluded Phaco, and Occluded Phaco, and CASE settings.
Phaco Power is a combination of stroke length, frequency and handpiece
efficiency. A preset power setting of 30% using linear control allows you the
ultimate control during phaco. Adjustments to phaco power depend on factors that
include nuclear density, your preferences and your experience.
Phacoemulsification mode lets you set four submodes with different settings. You
can adjust the individual parameters of each submode.
Figure 5.6 – PHACO Submodes

chapter.
