A phaco tip sample was returned for evaluation.The front section of the tip was received still in the infusion sleeve.No lot number was identified with this complaint; therefore, a lot history review could not be conducted.A visual inspection of the phaco tip received was performed and deemed nonconforming.The tip is broken at the transition between the cone and cannula.The break area is slightly jagged with part of one section of the wall pushed inward.The wall thickness at the break area is even.Wear is present on the threads and back of flange.The complaint does confirm the phaco tip is broken.The exact reason of how and when the phaco tip became broken cannot be determined from this evaluation.The most likely reason for tip breakage is from a machine parameter not appropriate for this tip, tuning without water flow, occluded tip, or an improper sleeve installation.(b)(4).
