The lens was returned for evaluation.Microscopic examination was performed and observed a cut in the optic with a small piece of the optic missing; the haptics were intact but twisted.A review of the device history record (dhr) did not identify any anomalies or nonconformities that could be related to this event.The lot history, trend analysis, risk analysis, and/or directions for use review were considered acceptable, with the product performing within anticipated rates.Based on the available information, the root cause could not be conclusively determined.
