The design history file was reviewed; no deviations or issues were detected.The lot was manufactured according to specification.The complaint sample was returned to the manufacturing site in heidelberg.The sample was loose in a bl5114 stellaris premium vacuum phaco pack with no transport protection.The broken off piece of the silicone sleeve was returned as well.The visual inspection of the sample confirmed that the silicone sleeve was severely damaged and the tip was completely broken off.Therefore, the reported problem was duplicated.An instrument in this condition cannot only not function, but also would not have passed the final quality check.Therefore, the damage occurred during surgery due to applying to much pressure on the sleeve.The strong rubbing of the sleeve on the membrane then led to the tear.Therefore, the root cause was determined to be user error.The lot history, trend analysis, risk analysis and/or directions for use review were considered acceptable, with the product performing within anticipated rates.No corrective action required.The investigation is complete.
