Introduction
Device Description
VERITAS Vision System Console
Operating room teams contributed significantly to the successful design of the system
console. The solid wheel base and locking wheels make the console stable and smooth
rolling. An adjustable height Mayo tray accommodates the handpieces and tubing. The
VERITAS Remote Control uses standard commercially available AA batteries for easy
replacement. The foot pedal can be stored on a hanging hook when not in use.
VERITAS Vision System Display (Graphic User Interface–GUI)
The system graphic screen display is easy to read and easy to operate. You can see at a
glance the status of the system. The screen gives you visual indication of operating modes,
settings, and system status. Messages cue you through the procedure with illustrations and
prompts to indicate proper connections or system selections. Information is provided to help
resolve error messages.
Prime/Tune
Before the start of each surgical case, the system requires that you run prime, tune or prime/
tune. The prime mode incorporates the function of clearing the tubing of air, then fills the
tubing and completes the fluid aspiration check and the vacuum check. The tune mode
incorporates an ultrasonic power calibration check and safety check for the attached phaco
handpiece. The prime/tune mode allows the system to prime and tune the handpiece at the
same time.
Dual Pump
The system provides a fluid aspiration system that uses either a peristaltic (flow-based) pump
or a Venturi (vacuum-based) pump system. The surgeon can use both the peristaltic pump
and the Venturi pump in the Phaco, Irrigation/Aspiration (I/A), and Vitrectomy surgical
modes.
Continuous Irrigation
Continuous Irrigation opens the irrigation valve for a collection of balanced salt solution
during a case, independent of the foot pedal or prime cycle. Continuous irrigation can be
used to fill cups prior to prime/tune and is immediately available by way of the touchscreen
monitor. Tap the Cont. Irr. button to open the valve and start the flow of irrigation fluid. Tap
the button again to close the valve and stop the flow of irrigation fluid. Surgeon control of
continuous irrigation with the foot pedal is also available. The cup fill feature can be used in
place of continuous irrigation to fill a cup. The cup fill feature is only available on the Prime/
Tune screen. (See “Prime/Tune” on page 4-20 for detailed information.)
Continuous Irrigation Auto-Off (Cont. Irr. Auto-Off)
Continuous Irrigation Auto-Off (Cont. Irr. Auto-Off) is available in the Surgeon Settings.
When this feature is enabled, continuous irrigation will automatically turn on when the foot
pedal is pressed, and automatically turn off when the handpiece is removed from the anterior
chamber and the foot pedal is released. The time at which continuous irrigation
