The user facility in (b)(6) reported during the irrigation/aspiration step, an audio message said ''purge finished'', and the pressure went up to 520mmhg.The patient received an implant, there was a chamber puncture without vitreous infiltration into the anterior chamber.The procedure was extended by more than 30 minutes.General anesthesia was not given since the patient has parkinsons, however twice the initially planned dose of ketamine, supplenta and midazolan were given.The patient was observed post op, no visual acuity done, however, the patient indicated they can see better.The user facility reported receiving error messages from the system of, ''the cassette vacuum check is in progress," "please insert the cassette," and ''the fluid level sensor could not be read,'' but did not stop surgery.The surgeon's concern is that although the implant is in place, a haptic is behind the posterior capsule (there is no vitreous rising because the hyaloid is not broken), and the other haptic is positioned in the capsular bag.The risk is that the hyaloid will tear, and the implant will fall into the posterior segment.The patient was seen on post op day 1 and day 8, no further treatment needed except regular monitoring by surgeon.The hyaloid did not break, and no vitreous is coming up.One haptic of the implant remains in the bag and the distal haptic behind the posterior capsule.
