Ultraow
®
II (I/A) Handpiece
Prior to each procedure inspect the two O-rings where the tip screws onto the
Ultraow
®
II I/A handpiece. If damaged or missing, replace the o-rings. If in doubt,
contact Alcon's Technical Services Department.
WARNINGS!
Use of non-Alcon surgical reusable or disposable I/A handpieces that do not meet
Alcon surgical specications, or use of an Alcon handpiece not specied for use with
the Centurion
®
Vision System, may result in a uidic imbalance. This, in turn, may
cause a shallowing or collapsing of the anterior chamber.
Exceeding the recommended level of 100 mmHg (133 hPa) with a 0.5 mm or larger
I/A tip may cause anterior chamber shallowing and/or incarceration or tearing of
posterior capsule.
I/A tips are not to be used with a phaco handpiece.
Recommended Vacuum Range for I/A Tips
It is important that only the proper size I/A tip be used when operating with maximum
vacuum. Only 0.2 mm or 0.3 mm I/A tips should be used with vacuum limits above
100 mmHg (133 hPa). I/A adjustable vacuum range is 0 - 700 mmHg (0 - 933 hPa).

Vitrectomy Probe
The vitrectomy probe, a guillotine vitreous cutter, is intended for single use only.
Vitrectomy cutting performance may vary at high altitudes. Consult Alcon Technical
Service for additional information.
WARNINGS!
Do not test or operate vitrectomy probe unless tip of probe is immersed in BSS
®
sterile irrigating solution or distilled water or is in surgical use. Irreparable
damage to the probe and tip can result if run dry.
Perform visual inspection of accessories for burs or bent tips prior to use.
Connect pneumatic tubing connectors from vitrectomy probe to console prior to
initiating prime of probe. Initiating prime of the vitrectomy probe, or running the
vitrectomy system, with one or both pneumatic connectors disconnected may cause
the ow of non-sterile air over the sterile eld for a brief moment.
Do not use vitrectomy probes that are not approved for use on Centurion
®
system.
After lling and testing, and before surgical use, verify that the probe is properly
actuating and aspirating. This may require lowering cut rate to achieve good
visualization. The port should always remain in open position in footpedal position 1.
If cutting port is partially closed while in position 1, replace the probe. Prior to entry
into the eye, and with tip of probe in sterile irrigating solution, the surgeon
should step on the footpedal for visual verication that the probe is cutting:
• If the cutter is observed to not fully close, or does not move when the probe
is actuated, replace the probe.
• If cutting port is partially closed while idle, replace the probe.
• If air bubbles are observed in the aspiration line or exiting the probe tip during
priming, replace the probe.
• If a reduction of cutting capability or vacuum is observed during the surgical
procedure, stop immediately and replace the probe.
