Abstract:
1. A method for controlling infusion pressure during an intraocular surgical procedure, the method comprising: determining an infusion pressure of a patient's eye with a first pressure determining device; determining a blood pressure indicative of a patient's central retinal artery blood pressure with a second pressure determining device; determining, with a processor, an estimated critical closing pressure of a central retinal artery of the eye based on the blood pressure indicative of a patient's central retinal artery blood pressure; comparing, with the processor, the infusion pressure to the estimated critical closing pressure; and triggering an alarm when the infusion pressure reaches a selected pressure relative to the estimated critical closing pressure, wherein determining a blood pressure indicative of a patient's central retinal artery blood pressure with a second pressure determining device comprises:
