When such a choice is needed, a drop list appears near the surgical control as shown in Figure 2-49.Surgical Control withdropdown list.Dropdown list expanded.Figure 2-49 Surgical Control with Dropdown List (Advanced Display Mode)NOTE: The control is shown in the "Advanced Display Mode" which is a selection made in the Doctor Settings display. Go to Options/Doctor Settings/General and the display modes are shown on the right of the display. For additional information see Menu Bar: Options in this section of the manual.
2.62 8065751025Constellation® Vision SystemSurgery Screen: Surgical StepsA “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 ProceduresA 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 ProcedureAccurus 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. •••••••
8065751025 2.63Constellation® Vision System Figure 2-51 Surgical Step Panel - Custom ProcedureSelected Step Scroll Button(s)Figure 2-50 Accurus® Classic Surgery ScreenSurgery Screen: Surgical Procedures - Custom ProcedureCustom 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.
2.64 8065751025Constellation® Vision SystemSurgery Screen: The Surgical Step PanelThe 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.••••••••Figure 2-51a Surgical Step Panel Scroll ButtonsSurgery Screen: Surgical Submode ButtonsFor Accurus Classic procedures, the submode buttons are always displayed as shown in the Figure 2-49a. The submode buttons act like radio buttons (just like the step buttons) and the currently selected sub mode is highlighted. For Custom procedures, the submode buttons are only displayed when the user presses the currently selected step. The submode buttons are then displayed for five seconds enabling the user to select the desired submode. After five seconds, the submode buttons will disappear.
8065751025 2.65Constellation® Vision System SURGICAL MODES AND SUBMODESThe Constellation® Vision System offers nine surgical modes that can be customized to meet the needs of each surgeon. Table 2-1 lists each mode and its associated submodes.TABLE 2-1.

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 ModeVitrectomy 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 andvacuum level. Values are adjusted using touch arrow keys, even when the footpedal isdepressed. Cutting and/or vacuum begins when the footpedal is pressed. •••
2.66 8065751025Constellation® Vision SystemFigure 2-52 Surgery Screen: Vitrectomy Mode-3D SubmodeVitrectomy: 3D SUBMODEIn 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.Aspiration PanelVacuum PanelConfiguration Button

U/S power may be linearly controlled from either zero to the operator specified value or pulsed. When the U/S handpiece is selected, irrigation, aspiration, and phaco power are provided to the handpiece tip. Phaco power is defined as being proportional to ultrasound displacement of the phaco tip. Amplitude of the ultrasound displacement of the phaco tip is proportional to the ultrasound power displayed on the console front panel. The user has the ability to adjust the aspiration rate, vacuum levels, and phaco power at any time during the surgical procedure via their respective adjustment arrows or remote control.The phaco Power Limit is increased or decreased via the front panel in incrementsof 5% from a minimum of 0% to a maximum of 100%. The amount of phaco powerdelivered to the handpiece is controlled by one of two methods: linear or fixedfootpedal 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.
