It was reported that while inserting an intraocular lens (iol), the inserter tip cracked and the iol became stuck in the inserter.The lens was halfway in patient¿s eye, and the surgeon removed the lens intraoperatively.The intraoperative lens removal did not require incision enlargement or sutures.There was no injury to the patient.A backup lens of the same model and diopter was successfully implanted.

The product evaluation confirmed the failure mode.Splitting can occur in cases of incorrect delivery or errors during delivery.For example, if the plunger bypasses the lens and rides on top of the lens during the delivery, it will add bulk to the lens and could potentially cause splitting.Based on the evaluation of the returned device and the investigation, the inserter was most likely split during delivery due to user error.A review of nonconformances (ncs) for the previous twelve months was performed.There were no ncs that would contribute to the reported event.The trend analysis, risk analysis, and directions for use are considered acceptable with the product performing within anticipated rates.The most probable root cause is operational context.User related factors (such as loading or handling techniques) and/or procedural factors (such as lens and inserter interaction) might have contributed to the event.No additional investigation or corrective action is necessary at this time.
