Changing Irrigation Flow
Use extreme caution when you lower or raise the balanced salt solution bottle to
decrease or increase fluid flow and pressure. If you lower the bottle too much it can
cause the anterior chamber to collapse. If you raise the bottle too high it can cause
the anterior chamber to deepen. To make sure that the bottle height does not go too
high, you can set the maximum bottle height on the Diagnostics screen.
Note: Use a new bottle of balanced salt solution at the start of each case.
Phacoemulsification without Adequate Irrigation
Operating phacoemulsification without an adequate irrigation flow can result in an
elevated temperature of the tip and subsequent damage to the eye tissue or could
cause the chamber to collapse. Confirm that there is irrigation flow before you
initiate phacoemulsification. A tight wound or the angle of the needle next to the
wound can also constrict the irrigation flow by pinching the coaxial irrigation
sleeve assembly on the needle of the phaco handpiece.
Power Failure during Surgery
If there is a loss of power during a procedure, you need to:
• Withdraw the handpiece from the eye
• Release the footpedal to Position 0
When power is restored:
• Select Prime/Tune to reprime the fluids and tune the phaco handpiece. Use
Bypass to reduce the length of prime time.
• Select the mode that was in use when power was lost (PHACO, IA, Vitrectomy
or Diathermy)
Connecting Handpieces
It is very important that the electrical connectors on the handpieces are completely
dry before they are connected to the WHITESTAR SIGNATURE™ System
receptacles. You can receive a “Handpiece Ground Fault Error” message if the
connector is wet.
Handling the Phaco Handpiece
The phaco handpiece is a very delicate instrument and must be handled with
EXTREME care. If the handpiece is dropped or receives any other significant
impact, the handpiece will not work properly. The ultrasonic titanium phaco tip
must never touch any solid material while in use.
Always flush the handpiece immediately following surgery.
