FUSION™ Fluidics
System
The WHITESTAR SIGNATURE™ System has both a flow-based peristaltic pump
system and a vacuum based Venturi pump system. The patented microprocessor-
based system continuously monitors and controls intraocular conditions of the flow
and vacuum in the eye.
Chamber Stability Environmental (CASE)
CASE is an intelligent vacuum monitoring system used to regulate the maximum
allowable vacuum that is experienced following the occlusion of the phaco tip.
When the phaco tip becomes occluded, the vacuum rises. Clearing of the occlusion
while the vacuum is at a high level can lead to a post-occlusion surge. With CASE
enabled, the System monitors the actual vacuum levels and when the vacuum
exceeds a specific threshold for a specified duration, the System automatically
adjusts the maximum allowable vacuum setting to a lower predefined CASE
maximum vacuum level. When the occlusion is cleared, the System is
automatically restored to the original programmed maximum vacuum setting. This
function makes it possible to have a different maximum vacuum setting when the
needle is occluded than when the needle is not occluded.
Accessories WHITESTAR

Handpiece
The Phaco Handpiece has been designed with a straight-through aspiration channel
for more efficient removal of nuclear fragments, to minimize clogging and to
facilitate cleaning. The hand piece is lightweight, slim, and well-balanced, making
it comfortable to use and easy to manipulate.
Ellips™ Handpiece
An Ellips™ phaco handpiece is available for use with the WHITESTAR
SIGNATURE™ System. The Ellips™ handpiece provides both longitudinal and
transversal movement. The Ellips™ handpiece provides great followability and can
be used with either a straight or a curved tip.
Footpedal
The footpedal controls the various operating modes of the instrument, and all
settings are programmed through the user interface. The WHITESTAR
SIGNATURE™ Single Linear footpedal or the wireless Advanced Control Pedal
(dual linear) can be used with the system.
The footpedal design offers control through the use of increased linearity and
uniform pressure throughout the footpedal movement, easing foot and leg fatigue.
The degrees of movement for each footpedal position can be selected and saved in
memory for each surgeon/mode, pitch for the single linear footpedal only and pitch
and yaw for the Advanced Control Pedal giving the pedal dual linear functionality.
Reflux is activated by programmable switches, giving immediate response. The
footpedal is connected to the rear of the console by a cable or can be wireless as
with the Advanced Control Pedal.
