Patent number: 11051978Abstract: Ophthalmic surgical devices, systems, and methods for regulating aspiration from a patient's eye are provided. A vacuum pump in fluid communication with an aspiration line provides fluid aspiration from a vitreous chamber of the eye through the aspiration line. A sensor disposed adjacent to or inside the eye determines sensor data relating to an intraocular pressure (IOP). The controller receives the sensor data and regulates the aspiration in response to changes in the IOP, such as by controlling the vacuum pump. The controller may determine whether a fluid infusion to the vitreous chamber through an infusion line is below a maximum infusion level, regulate the infusion in response to the IOP being below a threshold value and the infusion being below the maximum infusion level, and regulate the aspiration in response to the IOP being below the threshold value and the infusion being at or above the maximum infusion level.Type: GrantFiled: May 9, 2017Date of Patent: July 6, 2021Assignee: Alcon Inc.Inventors: Tammo Heeren, Andrew David Johnson
