Figures & data
Figure 1 The machine panel display of the Quadrant Removal Setting (Quadrant Removal Step Button enlarged) in the procedure step toolbar shows a −2 vacuum rise with linear control (angled line) of torsional amplitude.
Abbreviation: IOP, intraocular pressure.

Figure 4 The machine panel display of the Epinucleus Removal Setting (Epinucleus Removal Step Button enlarged in the procedure step toolbar) shows linear control of vacuum and aspiration flow in foot position 2, which becomes fixed at their maximums in foot position 3 when linear control of continuous torsional amplitude becomes available. The iP feature is engaged but does not come into play in soft cataracts. The Epinucleus Removal Setting procedure step button is between the Sculpt and Quadrant Removal procedure step buttons in the procedure step toolbar along the bottom of the display.
