Event Description

It was reported that patient claimed to have felt heat while sculpting a groove in a nucleus with ellips fx handpiece.The surgeon alleged he had heard slightly unusual noise from phaco machine before he sensed the heat from the handpiece.He immediately took the tip out from the patient's eye.The incision received mild thermal burn.The surgeon confirmed that the handpiece became hot when he stepped footpedal.He replaced with the phaco machine and equipment of another company¿s product, and the surgery was successfully completed with 10 minutes delay.The wound was normally closed, there was no suture.No further information provided.

Correction: h6 type of investigation code 10 and investigation findings code 213 were included in the initial report.However, what was checked at the time of that report submission was the whitestar system which was a concomitant product and not the suspect product, the handpiece.The whitestar signature has its own report.Additional information: h6 type of investigation - code 10 h6 investigation findings code 213 field service performed check on the suspect product, the fx handpiece and it met all amo specifications.All pertinent information available to johnson & johnson surgical vision, inc.Has been submitted.

Manufacturer Narrative

Manufacturing record review: a review of the device history record (dhr) showed, there was no discrepancies or non-conformances experienced during manufacturing.The system and its components met all specifications prior to being released.Device evaluation: a video of the event was submitted and evaluated by our subject matter experts (sme).It is observed the development of bubbles in the handpiece during the sculpting portion of the surgery, with withdrawal of the handpiece and development of a mild thermal burn to the incision site.The reported event can be confirmed; however, it is not possible to speculate the root cause of the incident through observation of the video provided.Some potential root causes could include (but not limited to): 1) rapid heat-up of the hp typically comes from 5 potential sources: a.Obstruction in the irrigation pathway combined with higher phaco power % settings and higher/continuous duty cycle settings b.Obstruction in the aspiration pathway combined with higher phaco power % settings and higher/continuous duty cycle settings c.Phaco power % settings and/or duty cycle settings inadvertently changed to higher values d.Electronic circuit failure in the console e.Electronic circuit failure in phaco hp body or phaco hp cable 2) typically, the hub and shaft of the phaco tip heat-up much more rapidly than the higher thermal mass of the phaco hp.Since it was reported that the handpiece heated up very quickly, there is a higher probability that the fluid flow was occluded either up-stream or downstream of the phaco tip.Conclusion: based on the investigation results there is no indication of a product quality deficiency.All pertinent information available to johnson & johnson surgical vision, inc.Has been submitted.
