Event or Problem Description
A physician reported that the poor cutting during vitrectomy and cataract combination surgery.The surgery was completed on the same day.There was no report of patient harm.
Additional Manufacturer Narrative
Additional information provided in d.4., d.9., h.3., h.6.And h.11.One opened probe was received with a tip protector in a pouch.The sample was visually inspected and found to be nonconforming with orange/brown foreign material on the port face.The sample was then functionally tested for actuation and cut.The sample was found to be nonconforming for both functional tests.The probe was disassembled and the components inspected.Excessive wear observed on inner cutter when compared to the degree of wear based on continuous actuation of the probe visual standard photos.Gouge marks observed at the cutting edge and several other locations along the inner cutter.A review of the device history record traceable to the lot number obtained from the device¿s radio frequency identification tag, indicates that the reported product was processed and released according to the reported product¿s acceptance criteria.The complaint evaluation confirms the probe had a cut failure; the evaluation also indicates the probe had an actuation failure.The most likely cause for the poor cutting is the observed gouge marks on the cutting edge of the inner cutter of the probe.The root cause for the cutting-edge gouges and actuation failure as well as the foreign material observed is due to the excessive surgical use of the probe.The vitrectomy portion of the procedure is typically less than 20 minutes and it appears that the probe has experienced a use much greater than this typical timeframe.The excess usage of the probe will wear and damage the inner cutter such that the cutter function becomes poor, bent, or does not function at all.No action has been taken by the manufacturing site as it appears that the observed actuation and cut failures were due to excessive use of the probe by the user.All probes are 100% visually inspected and tested for actuation, aspiration, and cut during manufacturing.Any non-conformances found are removed from the lot and scrapped.Complaints are reviewed and monitored at regular intervals for any significant adverse trends.No adverse trends have been observed associated with the reported product and event.No further actions are required.The manufacturer internal reference number is: (b)(4).
