Abstract: A surgical cassette/pack usage tracker for tracking a number of uses for a cassette/pack to prohibit uses from exceeding a maximum amount. A usage tracker system engages with or scans a portion of the cassette/pack to determine the number of uses. In illustrative embodiments, an implement interacts with a film in the cassette after each use and determines remaining uses for the cassette/pack. In other embodiments, an implement interacts with a rotatable wheel that rotates with each use, the implement configured to permit the tracker to identify the number uses and determine remaining uses for the cassette/pack. When a maximum usage amount is reached, the tracker system may issue a warning, eject or reject the cassette/pack and/or disable the surgical device from further use.

Abstract: A system for detecting intraocular pressure events during phacoemulsification surgery having a surgical console, a handpiece having a proximal end being communicatively connected to an irrigation line and an aspiration line; a first sensor in communication with the aspiration line or the irrigation line for providing a first measurement value; and a second sensor in communication with the aspiration line for providing a second measurement value; and wherein at least one characteristic of the irrigation fluid or aspiration fluid in their respective lines is changed in accordance with the difference between the first measurement value and the second measurement value. A system for calibrating patient eye level and wound leakage; detecting occlusion or post occlusion surge; determining BSS usage or remaining in a container; and detecting a fluid line abnormality using a first sensor and a second sensor in different configurations and differences in first and second measurement values.

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 system and method for providing the intraocular pressure (IOP) in the anterior chamber of an eye during ocular surgery is provided. Determination of IOP may be performed using an algorithm that is a function of the static (inflow) pressure and/or dynamic (outflow) pressure. Static (inflow) pressure may be calculated as a function of one or more parameters, including bottle height, wound leakage, sleeve size, length of irrigation tubing and/or inner diameter of the irrigation tubing. Dynamic (outflow) pressure may be calculated as a function of one or more parameters, including aspiration rate, vacuum rate, tip size, compliance of tubing, length of tubing, and/or inner diameter of tubing. Additional parameters may also be considered in the algorithm such as patient eye level.

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.
