Surgery Screen: Surgical Steps
A “Surgical Step” identifies a related set of activities performed during a surgical
case. Examples are “Membrane Peeling” and “Core Vitrectomy.” A Surgical Step
is associated with a Surgery Mode and contains unique information relevant to that
mode such as the sub mode, which functions are on, and various values of surgical
parameters. Selecting a Surgical Step determines which surgical functions are
available. Surgical Steps that are grouped together form a Surgical Procedure.
Surgery Screen: Surgical Procedures
A Surgical Procedure describes which “Surgical Steps” are most likely to be
performed during a surgery. The goal is to organize the screen in such a way that the
surgeon can select steps “from left to right” as the surgery progresses. The user can
create custom procedures or modify existing procedures. A procedure must contain at
least one step and can contain as many steps as desired.
Note: See "Menu Bar: Procedure Selection" found ealier in this section for detail
information on creating and editing procedures.
Surgery Screen: Surgical Procedures - Accurus® Classic Procedure
Accurus Classic procedure is a special procedure that is designed to mimic the look
of the Accurus® instrument with the exception that the laser has been added. The
Accurus® Classic procedure has several unique properties:
Steps cannot be added or removed.
Steps cannot be moved.
Steps cannot be renamed.
All Steps will always fit on the screen so there’s no need for scrolling.
The sub mode buttons will always be visible if there is more than one sub mode
for that step.
The Accurus® Classic procedure contains one step for each surgery mode. However,
at any point in time only a subset or a “View” of the steps is displayed. The Views
differ depending on:
The Fluidics Operating Mode (Combined, Anterior or Posterior)
The connected U/S handpiece (defaults to Phaco if no U/S handpiece is
connected)
The screen shown in Figure 2-50a shows the Accurus® Classic procedure in
combined mode.

Surgery Screen: Surgical Procedures - Custom Procedure
Custom Procedures can contain any combination of steps in any order and with user
defined names as shown in Figure 2-51.
Custom Procedures are intended to contain all the steps that the user has included to
perform a certain task. However, in some cases the user may need to do something
that is not included in the current procedure. In addition to the manual method of
adding surgical steps through the Modify Procedure screen as described previously in
this section, the system automatically adds relevant step(s) when an instrument (such
as a Vitreous probe) is connected. For example if the user suddenly requires the use of
the laser, the system automatically adds a laser Step to the end of the procedure when
it detects the connection of a laser probe. Also, if a laser probe is already connected
when the procedure is selected, a laser step is added to the end of the procedure.

Surgery Screen: The Surgical Step Panel
The Surgical Step Panel organizes the set of activities (steps) to be performed during
a surgical procedure in a left to right sequence. The procedure may be customized as
desired to meet the needs of the surgeon and the case to be performed. The Step panel
provides the following functionality:
Shows which step is currently selected (note that a step is associated with only
one surgical mode).
Shows which sub mode is currently selected for that step.
Allows the user to select a new step.
Allows the user to select a new sub mode.
Allows the user to select a “hidden” step (if applicable).
A selected step has the following properties:
The area behind the icon is highlighted in blue.
The icon is animated.
Buttons for submodes are shown above the step button.
The Step buttons act as radio buttons in that only one step at a time can be selected
and a step must always be selected at any point in time.
The Scroll Buttons allow the user to navigate to “hidden steps,” i.e. steps that are
either to the left or the right of the visible steps. The scroll buttons are only visible if
the current procedure contains more steps than can fit on the Step Panel.
Figure 2-51a shows an example of a Step Panel with three hidden steps to the right.
The Right Scroll button is enabled and pressing it displays a list of the hidden steps.
Any of the steps can be selected from the list. The selected step will be highlighted as
the selected step on the panel and placed in the rightmost position.

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.

Surgery Screen: Vitrectomy Mode-
3D Submode
Vitrectomy: 3D SUBMODE
In the 3D submode, the user controls both the vitreous cut rate and the vacuum
pressure linearly. This submode allows for setting the treadle start and end values for
both the cut rate and the vacuum pressure. Additionally, in Advanced Display Mode
that is shown in Figure 2-52, the Forceps End Pressure can be changed.
In 3D submode, vacuum delivered to the probe and the probe cutting rate are both
regulated by the amount of footpedal depression. The display contains adjustable
values for vacuum level at footpedal start, vacuum level at full depression; and cut
rate at footpedal start, cut rate at full depression. A unique features of this mode are:
1. Vacuum can be set to start at 0 and rise to its maximum setting at full footpedal
depression, while the cutting rate can be set to start at its maximum setting and
decrease as the footpedal is depressed (or any combination thereof).
2. To ensure that not too much flow is generated when the footpedal is first depressed,
the vacuum level is ramped up from 0 to the set starting level during the first part of
the pedal travel.

arrows or remote control.
The phaco Power Limit is increased or decreased via the front panel in increments
of 5% from a minimum of 0% to a maximum of 100%. The amount of phaco power
delivered to the handpiece is controlled by one of two methods: linear or fixed
footpedal control.
In Flow Mode, the Aspiration panel is displayed while in Vacuum Mode, the Vacuum
panel is displayed. In “Standard” display mode, only the Flow mode controls
are available. When system detects an occlusion, an alarm sounds and the word
"Occlusion" appears on the extraction panel (in either vacuum mode or flow mode)
under the primary limit control’s label.
There are four submodes available in Phaco mode
Burst
Custom
Pulsed
Continuous
Phaco Mode: BURST SUBMODE
In the Phaco Burst submode fixed U/S power (Power %) can be adjusted for duration
(On Time) and time off between (Off Time) U/S power pulses. The frequency of
bursts is controlled with the footpedal from detent two to full treadle depression,
while the fixed burst length is set in milliseconds (ms). The actual percent of time U/S
power is activated is reflected in the Actual window.

The controls for each panel in Burst submode have the following functions:
Aspiration Panel:
Flow End Up/Down Buttons - Sets the flow level at full treadle.
Dynamic Rise Drop List - Select for the rise value. The rise value determines
the slope of the increase applied.
Flow Configuration Button - Displays the configuration popup.Simplifies large
value changes by providing slider controls. Also provides the capability to initiate
a drainbag change.
Vacuum Limit On/Off Button - Turns vacuum limit on or off. When the maximum
rate is reached, the flow can no longer be increased. If the Vacuum Limit is turned
off, the flow is limited only by the Start and End values.
Vacuum Limit Up/Down Buttons - Sets the maximum vacuum value.
Vacuum Limit Control Type Drop List - Determines whether the vacuum limit is
fixed or linear. In Fixed the limit is constant regardless of the vacuum level. In
Linear the limit varies depending on the vacuum level.
Vacuum Limit Configuration Button - Displays the configuration popup.
Flow/Vacuum Toggle (Advanced view only): Switch between Flow Mode and
Vacuum Mode.
