Ultrasound Test (Ultrasound adjustment and verification)
Every time a handpiece is connected or replaced, it is
necessary to perform a simple preliminary ultrasound test.
The purpose of this procedure is to tune the
phacoemulsifier unit on the connected handpiece,
verifying, at the same time, the correct functioning of the
system. At the end of the "Priming" procedure, or if it has
been skipped, the unit automatically starts the Ultrasound
Test procedure. If the adjustment and verification are not
successful, the message "Please check tip" is displayed, for
four seconds, and the user must repeat the preparation
procedure.
INFORMATION Phaco tip damage!
• Do not activate the handpiece with the phaco tip in the
air. The ultrasounds must be activated with the phaco
tip inserted into a test chamber filled with infusion
solution or into a container with sterile liquid at room
temperature. If these instructions are not followed, it
is possible to damage the phaco tip and/or the phaco
handpiece.
WARNING Risk of injury to the patient's eye!
Although the R-EVO SMART systems are equipped with a
sophisticated power control circuit to limit the power of
the ultrasound supplied to the eye, care must be taken not
to damage the endothelium of the eye (corneal damage).
• Use always the lowest ultrasound power,
sufficient for cataract removal.
• The incision should not be made too tight with respect
to the silicone sleeve and must allow a certain leakage
of balanced salt solution.
• Do not stress the incision or twists the sleeve while
trying to reach fragments of the nucleus in the eye.
• If the phaco tip is completely occluded by the nucleous,
the aspiration flow stops and the tip is no longer cooled
properly. Do not activate ultrasound for too long or high
levels if the phaco tip is occluded.
