Event or Problem Description
A (b)(6)-old patient underwent cataract surgery in the left eye on (b)(6) 2021 where the miloop and micor lens fragmentation system (extractor and drive) were used to fragment and remove the cataractous lens.The patient's posterior capsule tore during surgery.There was no loss of vitreous fluid, no vitrectomy, and no change to the intraocular lens implanted.The surgeon reported the micor "felt running at too high throttle" and he "got too close to the [capsular] bag".The surgical video revealed the following additional information and insight.It should be noted that the video resolution was low and it was not possible to identify exactly when the capsular tear occurred.The patient had a dark iris and a small pupil which required use of an iris retractor at the beginning of surgery.The miloop was used to bisect the patient's grade 3 cataractous lens.There were no problems with the technique used to execute the miloop procedure.There was no evidence of a device malfunction with the miloop or micor devices and there was no evidence of an overspeed condition.Based on the video evidence, it is possible that the iris retractor and surgical technique during its removal and/or bag polishing technique with another device may have caused the tear.Patient follow-up has been requested from the surgeon on several occasions, but no response has been received.
