5.4.1 PHACO (U/S) MODE FUNCTIONS
Prime: The Prime function is used during system setup to fill the administration tubing, tubing
cassette, and the ultrasonic handpiece test chamber with the irrigation solution, as well as to verify
that the handpiece is properly tuned.
To activate the Prime function, press the “Prime” soft-key on the console. The “Prime” soft- key will
be outlined in red. The aspiration pump will run for approximately 60 seconds, followed by an
automatic tuning of the ultrasonic handpiece. The Prime function can be deactivated at any time
by pressing the “Prime” soft-key a second time.
Tune: The “Tune” function is used to confirm that the attached ultrasonic handpiece meets the
required electrical specifications of voltage, current, phase, and frequency. While the tune function
is performed automatically at the end of a Prime cycle, it should be performed whenever a phaco
tip is replaced, or the Check Handpiece! error message is displayed.
Reset: The Reset function resets the Phaco “Total Time” and “Effective Time” to (00:00).
Purge: The “Purge” function is used to remove fluid from the irrigation and aspiration tubes
through the cassette and into the collection bag. To activate a Purge cycle, perform the following
steps:
5.4.1.1 Disconnect the ultrasonic handpiece and remove the irrigation and aspiration tubes.
5.4.1.2 Connect the irrigation and aspiration tubes together to form a closed loop.
5.4.1.3 Close the roller clamp on the administration tubing.
5.4.1.4 Disconnect the administration tubing from the solution container and the cassette.
5.4.1.5 Press the “Purge” soft-key. The Purge soft-key will be outlined in red. The fluid will be
purged from the irrigation and aspiration lines.
5.4.1.6 Dispose of the administration tubing set and collection bag according to your facility’s
waste requirements.
The “Purge” function can be deactivated at any time by pressing the Purge soft-key a second
time.
Reflux: The “Reflux” function is normally used to clear lens material from the aspiration line of the
ultrasonic handpiece when it becomes occluded. Reflux is also available in all functions.
The foot pedal has the Reflux position on the “Right Side Kick Switch”, by default.
To activate the Reflux function, press and hold the Right Side Kick Switch.
Reflux may have to be performed a few times depending on the occlusion.
Factory Arrow: The factory arrow is used to store user-defined programs. Pressing the arrow will
display the “User Programs”. If any of the User Programs are selected, the Mode parameters of
the user program will be displayed. If no programs have been saved, the factory list will be empty
and all Modes will be set to their “Factory Default” values. (See Section 5.9.1 Programs Mode)
