The phaco systems light-weight, reliable and non-skid Foot pedal treadle is made of
water resistant and highly durable construction with a rugged, 10 foot polyurethane cable.
With it's easily recognizable audible and vibrational knock to indicate Foot pedal stages,
it outperforms its more cumbersome and less reliable competition.

Function versus Mode
Irrigation pinch valve is actuated, permitting the elevated irrigation solution
to safely maintain intraocular pressure.
Enables Foot pedal proportional aspiration rate via Peristaltic pump, permitting
required vacuum for effective aspiration.
Enables Foot pedal proportional ultrasonic ( U/S ) Power to be delivered to the attached
ultrasonic handpiece with maximum U/S Power at Position 4.
Same as U/S  except U/S Power is
pulsed at 10 pulses/sec.
The Vitrector is actuated at selected cut rate whenever
treadle position is ≥ Position 2.
Actuates reverse peristaltic pump rotation (20cc/min.)
Electrically heat targeted tissue held by the Cautery forceps at the set cautery power.

Light-weight, reliable and non-skid.

Actual vacuum and requested aspiration rates displayed whenever treadle ≥ Position 2
with maximum aspiration rate at Position 4.
Peristaltic pump actuation is only enabled when selected maximum vacuum has
not been exceeded.
Any vacuum generated by the peristaltic pump is automatically and safely vented
whenever treadle position is returned ≤ Position 2.



Requested U/S Power is displayed whenever treadle position ≥ Position 3.
Aspiration rate is fixed at the selected aspiration rate.
