Abstract: A method for maintaining anterior chamber intraoperative intraocular pressure (IOP) is provided by receiving and/or detecting variables of a surgical system and utilizing those variables to monitor intraoperative IOP. Determining an IOP in real time during a surgical procedure either provides a notification to an eye surgeon or allows a target IOP of the anterior chamber of a patient's eye to be set and maintained.

Abstract: A pressure and vacuum pump including at least two diaphragm pump heads for providing vacuum and pressure simultaneously. The dual function pump reduces number of required pumps, is traditionally quieter, and enables the system to run at a lower duty cycle. A drive in the pump housing causes a connecting rod to oscillate a diaphragm to move up and down thereby causing air to be either drawn into an inlet or forced out via an exhaust.

Abstract: Variables of a surgical system are detected or received via one or more sensors to predict an intraocular pressure (IOP) and/or determine an IOP in real time during a surgical procedure. A notification to a surgeon or a target IOP is set and maintained as determined by Static IOP, dynamic IOP, and/or a total IOP combining both static and dynamic IOP of the anterior chamber of a patient's eye. Information collected about various components of the system are displayed on a user interface. The system uses the collected information to calculate the static IOP and/or dynamic IOP of the system, and the total IOP may be function of the static IOP and/or dynamic IOP measurements.

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.

Abstract: A smart automated phacoemulsification surgical system for reducing variables significantly by introducing a relationship among related variables that share the same functionalities or where they depend on each other. The system optimizes power applied and when the power reaches its maximum targeted value while the occlusion persists for an extended period of time. An automatic venting subsystem is configured to release cataract particles from the tip of the surgical instrument. An ultrasound power setting is configured to be reset to overcome power and occlusion stagnation in order to prevent applying too much ultrasound power and harming the eye tissues of a patient.
