Each surgical mode has as set of associated surgical panels. Some panels can have
different displays in following cases:
Standard vs. Advanced mode - In advanced display, these panels offer more
optional controls for setting and configuring its functions. Selecting Standard or
Advanced mode is done in Options\Doctor Settings\Miscellaneous. The default
mode is Standard.
Vacuum mode vs. Flow mode - By default, the posterior modes show the vacuum
panel for vacuum mode and the anterior modes show the aspiration panel for flow
mode (if available).
Bimanual mode - Vit, scissors, and VFC modes offer the surgeon the option of
controlling two instruments simultaneously such as a vitreous probe and a pair
of forceps (in Vit mode). This is referred to as Bimanual mode and the additional
instrument is activated by pressing the “Bimanual” button.
Vitrectomy Mode
Vitrectomy mode provides vitreous cutting and vacuum using a pneumatically
powered vitrectomy probe connected by tubing to a pulsed air pressure source and a
vacuum port. Four submodes are available, each with its own default cut rate and
vacuum level. Values are adjusted using touch arrow keys, even when the footpedal is
depressed. Cutting and/or vacuum begins when the footpedal is pressed.
