Surgery Start Up
Z370584 Rev. C Verify Irrigation/Aspiration Balance
4-17
Verify Irrigation/Aspiration Balance
We strongly recommend you verify that you balanced Irrigation/Aspiration properly for your
settings used in surgery.
Figure 4-17 — Irrigation/Aspiration Balance Procedure
To verify irrigation/aspiration balance:
1. In Phaco 1 mode, hold the handpiece at the approximate patient eye level.
NOTE: The numbers in the drawing Figure 4-20 correspond to the steps listed.
2. Occlude the aspiration line just below the handpiece, while you press and hold the foot
pedal in position 2.
3. The actual vacuum level should rise to the preset level.
4. Release the aspiration line and then watch the test chamber to ensure the test chamber
does not collapse. A slight shallowing of the test chamber is normal.
5. If the test chamber collapses, raise the IV bottle height or lower the vacuum setting.
6. Pinch the irrigation tubing at the handpiece and watch for the test chamber to collapse.
7. Release the irrigation line and the test chamber should fill.
8. Tap Reset in the upper left corner of the screen to open the Reset Timers dialog box. Tap
Yes to reset the timers. You are now ready to begin surgery.
