A surgeon reported that during a combined cataract and vitrectomy surgery, the infusion cannula failed to lock into the trocar.After everything had been set up and the cassette had been primed, the surgeon started the surgery by placing the trocar into the eye and then placed the infusion cannula into the trocar.As soon as the infusion pressure was turned on, the infusion cannula popped out of th e trocar.A new pak was opened and this time the infusion cannula locked with the trocar and surgery could be completed.This is one of five mdr being filed for this facility.
