Abstract
A method includes calculating in real-time a correlation between vacuum readings and pressure readings of respective aspiration and irrigation channels of a phacoemulsification handpiece engaged in a phacoemulsification procedure in an eye. Upon detecting an increase in the vacuum readings and an increase in the pressure readings, a current level of the correlation is checked. Provided that the current level of the correlation is above a given value, an anti-vacuum surge (AVS) mechanism is activated, the AVS mechanism fluidly coupled with at least one of the irrigation and aspiration channels.
