6.3 SYSTEM PREOPERATIONAL CHECKS
6.3.1 PRIME CYCLE
Perform a Prime cycle to fill the system tubing with irrigation solution and to tune the handpiece.
6.3.1.1 Place a test chamber over the phaco tip and sleeve until fully seated.
6.3.1.1 Open the roller clamp on the administration tubing set.
6.3.1.1 On the screen of the console, select the U/S mode.
6.3.1.2 On the console front panel, press the “Prime” soft-key.
NOTE: A successful Prime cycle will be indicated by a “Handpiece Tuned” message. If a different
message is displayed, follow the instructions on screen and / or refer to Section 7.8 System
Messages and Section 10.0 Troubleshooting. Refer to Section 5.4.1 Phaco Mode Functions for
additional information about the priming and tuning functions.
6.3.2 SYSTEM FLUIDICS TEST
6.3.2.1 Place and maintain the ultrasonic handpiece at patient eye level.
6.3.2.2 In the Normal U/S Mode, depress the foot pedal to “position two (2)” and hold.
6.3.2.3 Pinch off the irrigation tube and verify that the test chamber collapses. This action
confirms aspiration.
6.3.2.4 Release the irrigation tube and observe that the test chamber refills with fluid within a
few seconds. This action confirms irrigation.
6.3.2.5 Pinch off the aspiration tube and verify that the Vacuum increases to 200 mmHg, the
default preset value. An occlusion message is displayed.
6.3.2.6 Release the aspiration tube and confirm that the test chamber does not collapse or
dimple. No change in test chamber indicates system is now ready.
6.3.2.7 If test chamber collapse occurs, complete the following as required, then repeat test
steps 5.3.2.5 through 5.3.2.6 until the test chamber does not collapse or dimple:
6.3.2.7.1 Make sure all connections to the u/s handpiece are secure.
6.3.2.7.2 Avoid severe bends / kinks in all tubing.
6.3.2.7.3 Make sure the u/s handpiece is free of obstructions.
6.3.2.7.4 Increase irrigation solution elevation.
6.3.2.7.5 Decrease maximum Vacuum setting.
NOTE: Section 6.3.2 Perform a System Fluidics Test & Setup must be repeated to completion if
the U/S Vacuum setting is increased and / or if irrigation solution elevation is decreased.
