Patent abstract

The present invention provides a system for managing occlusions during phacoemulsification surgery. More specifically, the present invention provides a user of a surgical console an alert when a partial or full occlusion of a surgical tool causes the vacuum pressure to become greater than a predetermined pressure threshold setting and automatically reduces the vacuum pressure when the predetermined pressure threshold setting is exceeded.
