WARNINGS!
Appropriate use of Centurion
®
Vision System parameters and accessories is
important for successful procedures. Use of low vacuum limits, low ow rates, low
bottle heights, high power settings, extended power usage, power usage during
occlusion conditions (beeping tones), failure to sufciently aspirate viscoelastic
prior to using power, excessively tight incisions, and combinations of the above
actions may result in signicant temperature increases at incision site and inside
the eye, and lead to severe thermal eye tissue damage.
Good clinical practice dictates testing for adequate irrigation, aspiration ow, reux,
and operation as applicable for each handpiece prior to entering eye.
Ensure that the tubings are not occluded during any phase of operation.
If the handpiece test chamber is collapsed after tuning, there is a potential of low
irrigation ow through the handpiece and may result in a uidic imbalance. This, in
turn, may cause a shallowing or collapsing of the anterior chamber.
Avoid setting the patient above the FMS unless PEL is used. Operating with the patient
above the FMS without PEL adjustment will result in a lower irrigation pressure than
indicated on the display, and possible underventing.
Use of BSS
®
irrigating uid bags other than those approved by Alcon for use in the
active uidics system can result in patient injury or system damage.
Use of appropriate technique and settings is important to minimize fragments and
turbulence.
Do not remove the FMS during the surgical procedure.
In the event of a system error release footswitch to the up position.
Improper handling or removal of dual irrigation handpiece tip from eye may cause
draining of the uidics system.
CAUTIONS
• Modication of the equipment is NOT allowed without prior authorization
from the manufacturer. If this equipment is modied, appropriate inspection
and testing must be conducted to ensure continued safe use of the equipment.
• Avoid spilling BSS
®
irrigating solution, or moisture of any kind, around the
electrical handpiece connectors.
• Do not spray any liquid (i.e. cleaning solution or water) upward into the
console vents.
• Do not push or pull the unit by the display, the tray, or the IV pole. Wrapping
around the rear and sides of the system is a handle provided for moving the
instrument. The unit should be pulled and not pushed, especially over elevator
and door thresholds.
