Alcon Centurion
Alcon · Model Centurion
Active Fluidics Technology - An automated system that optimizes anterior chamber stability by allowing surgeons to proactively set and maintain target intraocular pressure (IOP) within the eye during the cataract removal procedure Balanced Energ Technology - Enhances phacoemulsification efficiency through proven OZil® Intelligent Phaco and the INTREPID® Balanced Tip probe Applied Integration - Innovative design that enables the new system to be seamlessly integrated with multiple cataract surgical technologies Improved ergonomic design, wireless footswitch and intuitive touch-screen display.
Key tips
- ·Verify laser output with a real power meter, not the unit's own display - the display can drift independently of true output.
- ·Take "the image looks a little off" reports seriously - optical alignment drift is usually gradual, not sudden.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Poor phaco / vacuum performance
HighSymptoms: Weak ultrasonic power, poor followability, vacuum will not build or holds poorly, surge.
Root cause: Worn phaco handpiece / tip, a cracked or worn tubing / cassette, or a pump / vacuum-sensor fault.
Handpiece fault (phaco / I-A / vit)
MediumSymptoms: Handpiece will not tune, overheats, no irrigation / aspiration, cutter not cutting (vit).
Root cause: Worn or damaged handpiece, or its connector / cable.
Fluidics / cassette-detection fault
MediumSymptoms: Cassette not recognised, priming / tuning fails, fluid leaks at the cassette.
Root cause: Cassette-detection switch, the peristaltic / Venturi pump, or fluidics seals.
Footpedal fault
MediumSymptoms: Pedal positions not registering, wireless pedal not pairing.
Root cause: Worn footpedal or its cable / wireless module.
Pneumatics fault (vitrectomy cutter)
LowSymptoms: Cut rate low or erratic, cutter will not drive.
Root cause: Internal pneumatic valve or a supply-pressure fault.

PM Checklist
Preventive-maintenance tasks typical of this equipment class. Perform to the manufacturer's procedure and your facility's policy - this is general reference, not a schedule for this specific unit.
- ·Optical alignment / calibration check
- ·Lamp or laser output verification
- ·Annual full PM
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Poor phaco / vacuum performance / weak power
- Fit a fresh tip and test-tune the handpiece in a beaker of BSS.
- Fit a new cassette / tubing and re-prime.
- Run the fluidics / vacuum self-test and check for leaks at the cassette.
- Verify vacuum and rise time against the service spec.
- Send the handpiece for service or exchange if it will not tune.
Symptom: Cassette / tubing not recognised / priming fails / fluid leak
- Reseat the cassette and confirm it clicks home.
- Check the cassette-detection switch.
- Inspect the peristaltic / Venturi pump and the fluidics seals.
- Re-run prime and tune.
- Replace the detection switch or the pump components as isolated.
Symptom: Footpedal fault (positions not registering, wireless not pairing)
- Check the footpedal cable / connector or re-pair the wireless pedal.
- Test each pedal position and treadle range.
- Replace the footpedal.
- Confirm the console responds to every position.
- Update the console firmware if a pedal issue is a known fault.

Safety & Recalls
Synced live from the FDA openFDA API.
- RECALL
Due to complaints of particulates, residue, occlusions, and bent tips for sterile cannulas.
- RECALL
Sterility; Steril surgical procedure packs contain incomplete seals.
- RECALL
The grounding pin within the Power Entry Switch on certain systems was susceptible to detachment when the AC power cable is removed.
- RECALL
Alcon is conducting this Voluntary Medical Device Removal for specific lots of its CENTURION FMS packs due to the possible presence of a molding irregularity found within the aspiration luer which may result in a reduction of vacuum within the aspiration line.
