Abstract
A system includes a user interface and a processor. The user interface is configured to receive a user-selected confidence level of measurement of intraocular pressure (IOP) for detecting vacuum surge in a phacoemulsification system. The processor is configured to (i) based on the user-selected confidence level, calculate a number of IOP readings needed during phacoemulsification procedure to identify an imminent vacuum surge, (ii) during the phacoemulsification procedure, receiving sensor readings of IOP, (iii) upon reaching the calculated number of the readings, estimate whether a consistent drop in IOP occurred between the readings, and (iv) upon estimating a consistent drop in IOP, activate an anti-vacuum surge (AVS) mechanism to mitigate the imminent vacuum surge.
