The CENTURION™ OZIL™ HANDPIECE is not limited to a number of uses. As stated in the Directions for Use (DFU), reuse is limited by physical damage and failure of pre-surgical check cycle. Each time the handpiece is connected to the driving console, it performs a check cycle. If the handpiece performs improperly and fails the check cycle, remove it from the driving console and return it to Alcon for evaluation. Before each use, the handpiece and power cord should be inspected for damage (e.g. nicks, crimps, dents and exposed wires). If the handpiece is damaged it should be immediately removed from service. Use of a damaged handpiece may result in serious permanent patient injury.
