Event or Problem Description
It was reported that following a cataract surgery, the surgeon inadvertently created a small descemet's tear in the anterior angle during the implantation of a stent from a trabecular micro bypass stent system in the patient's right eye (od).The report noted that compromised intraoperative visualization due to "a lot of heme", patient movement, and patient anatomy precluded implantation contributed to the reported event.Additional information has been requested.
