Venturi
The refined pump achieves vacuum rise at shorter
times than the venturi pump with use of a CV-30000
phaco cassette and provides secure nucleus retentivity
of a phaco tip and enhanced followability.
It achieves vacuum rise at similar times as the venturi
pump with use of a CV-30000 vit cassette and provides
quick vacuum response during vitreoretinal surgery.

Advanced Cassette System
Phaco cassette
The phaco cassette incorporates the unique
Irrigation Assist Bottle (IAB) to improve
anterior chamber stability. The IAB
contains irrigation solution and air. When
the occlusion breaks, the air in IAB
expands and enables the surge reduction
with instant increase of irrigation flow
into anterior chamber.

Phaco Innovation
VIS (Variable Intervals and Strokes)
Dual-oscillation of conventional pulse and
ultra-short duration pulse
The nucleus can be emulsified easily with less
energy by using dual-pulse oscillation.
The dual-pulse oscillation provides overlapping and
separation of conventional pulse and ultra-short duration
pulse. The ultra-short duration pulse can provide high
energy or low energy for an extremely short duration.
VIS provides numerous customizable oscillation settings.

APS-Plus (Auto Pulse System-Plus)
Efficient control of ultrasound and aspiration pump
Power level
Both ultrasound and aspiration pump automatically stop immediately after occlusion breaks to minimize surge.
When the phaco tip is occluded, an automatic increase in the pulse duty provides a highly efficient control for
phacoemulsification. The change in IOP can be controlled when the occlusion breaks.
Low-duty pulse High-duty pulse Ultrasound stops Low-duty pulse
when a rapid
surge occurs.

Cut Control
High Speed Vitreous Cutter
Maximum 8,000 cuts / min*
The excision per single cut is decreased with a high speed cutter and it is effective for
precise treatment proximal to the retina.
*Available for AP type. (Maximum 5,000 cuts / min is available for A type.)
Pro-Pedal Mode
Desired setting with smart software
Cutting rate, flow rate, and vacuum can be independently controlled and modified in
three dimensions. This software improves performance during vitreoretinal surgery
and efficiency of vitreous body excisions.
