Phacoemulsification (PHACO)
The Phacoemulsification mode is used to break up (emulsify) the nucleus of the
lens and then allows the nucleus of the lens to be aspirated 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. Phaco
time is displayed in minutes and seconds. The convenient selection of linear or
panel preset phaco power, in a variety of power delivery options (pulsed, burst,
transversal), provides increased precision and control.
The WHITESTAR
®
Technology allows you to safely remove all lens types through
small incisions with single-mode, single-instrument convenience.
The WHITESTAR
®
Technology is a patented software application proven to
change the characteristics of phacoemulsification using little or no ultrasound. This
is done by changing the thermal properties and improving control of the lens
without reducing the cutting power or changing technique or efficiency.
CASE One Touch
The One Touch button simplifies the programming of the CASE function and
allows you to easily define the basic CASE settings once. The CASE function can
then be adjusted quickly with the CASE One Touch settings on the surgical
screens. When these controls are used, the CASE functionality can be changed to
provide enhanced control or improved efficiency to suit any particular combination
of cataract density, surgical technique or personal preferences.
Irrigation/Aspiration (IA)
The Irrigation and 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. A peristaltic pump provides a
predictable and stable aspiration rate. Complete control is achieved with
“Aspiration Rate” and “Vacuum”. Irrigation is gravity-fed.
The gravity-fed mode is regulated by adjusting the height of the balanced salt
solution bottle. This mode gives you flexible control of each case with
independently adjustable vacuum level and flow rate settings.
Vitrectomy (VIT)
The Vitrectomy mode is used to remove vitreous from the eye during surgery. The
WHITESTAR SIGNATURE™ 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.
