Introduction
When using the system with the Advanced Infusion Program, the effective bottle height
includes an extra 30 cm to the programmed IV Pole height due to pressurizing the irrigation
source.
VERITAS Vision System Operating Modes
The design of the system provides all the operating modes and surgical capabilities that the
anterior segment surgeon or the cataract surgeon requires. These capabilities include:
Phacoemulsification (Phaco)
You use the phacoemulsification mode to break up (emulsify) the nucleus of the lens. You
then aspirate the nucleus of the lens from the eye through a small incision. The continuous
autotuning circuitry maximizes the emulsification efficiency for each lens density, even
varying densities within the same lens. The system displays phaco time in minutes and
seconds. The convenient selection of linear or panel preset phaco power, in a variety of
power delivery options (continuous, pulsed, burst), provides increased precision, and
control.
The WHITESTAR Technology allows safe removal of all lens types through small incisions
with single-mode, single-instrument convenience.
The WHITESTAR Technology is a patented software program proven to change the
characteristics of phacoemulsification using little or no ultrasound. The WHITESTAR
Technology changes the thermal properties and improves control of the lens without
reducing the cutting power or changing technique or efficiency.
Irrigation/Aspiration (I/A)
The Irrigation/Aspiration mode allows for controlled aspiration of cortical material from the
eye, while maintaining intraocular stability, by replacing the aspirated material with a
balanced salt solution. This mode gives you flexible control of each case with the
independently adjustable vacuum level settings and flow rate settings. A peristaltic pump
provides a predictable and stable aspiration rate. “Aspiration Rate” and “Vacuum” settings
allows for complete control. Irrigation is gravity-fed.
NOTE: The vacuum units can be set to either mmHg or kPa. To set the vacuum units go to
Configuration, Set Vacuum Units.
You can regulate the gravity-fed irrigation by adjusting the height of the IV pole.
Vitrectomy (VIT)
You use the Vitrectomy mode to remove vitreous from the eye during surgery. The system
uses air pressure to drive the vitreous cutter. The wide range of user-controlled,
programmable cut rates supports both anterior segment and posterior segment surgeries.
Diathermy (DIA)
Most surgeons use the Diathermy mode to coagulate blood vessels during the procedure and
by some surgeons to “coag” the conjunctiva at the end of the procedure. An isolated output
frequency allows noncontact tissue coagulation, eliminating adhesion, and traction. Also,
