Patent number: 11950969Abstract: A tracking system for quantifying retinal traction on a retina of a patient eye includes an indicator device, a stereo camera, and an electronic control unit (ECU). The stereo camera collects and outputs stereo image data. The ECU, which is in communication with the indicator device, executes a method by receiving the stereo image data from the stereo camera during an ophthalmic procedure and thereafter assigning tracking points as coinciding pixels within stereo image pairs. The ECU also automatically performs a digital image correlation (DIC) process using the stereo image pairs to ascertain relative motion of the tracking points, and associates relative motion of the tracking points with the retinal traction using a traction map. A numeric traction quotient is generated that is indicative of magnitude of retinal traction. The ECU executes a control action using the indicator device based on the numeric traction quotient.Type: GrantFiled: September 30, 2021Date of Patent: April 9, 2024Assignee: Alcon Inc.Inventor: Niccolo Maschio

Patent number: 11752036Abstract: Particular embodiments disclosed herein provide a membrane delamination device for delaminating a membrane from a retina of an eye. The membrane delamination device comprises a blade, a first lever coupled to the blade, and a second lever coupled to the blade. The first lever and the second lever are at least partially housed by a first shaft of a hand-piece. The first lever is fixedly coupled to the first shaft. The second lever is fixedly coupled to the hand-piece. The blade at least partially extends beyond a distal end of the first shaft. The membrane delamination device is configured to be actuated as a result of longitudinal movement of the second lever within and in relation to the first shaft. The second lever moves longitudinally within and in relation to the first shaft due to an application of force to the second lever through the hand-piece.Type: GrantFiled: October 8, 2020Date of Patent: September 12, 2023Assignee: Alcon Inc.Inventors: Reto Grueebler, Thomas Linsi, Niccolo Maschio

Publication number: 20220192875Abstract: Certain embodiments provide an apparatus comprising a hand-piece, an outer tube coupled to the hand-piece, an inner tube housed within the outer tube and having a distal end coupled to a soft tip and a proximal end coupled to an adapter, a proximal end of the adapter coupled to a distal end of a valve, the valve slidably coupled to the hand-piece, and a core slidably coupled to the hand-piece and having a distal end coupled to a proximal end of the valve. To retract the soft tip, the valve is retracted, causing the adapter, the valve, and the core to slidably retract in a proximal direction in relation to the hand-piece, and to extend the soft tip, the valve is protracted, causing the adapter, the valve, and the core to slidably protract in a distal direction in relation to the hand-piece.Type: ApplicationFiled: December 7, 2021Publication date: June 23, 2022Inventors: Reto Grüebler, Simon Nicola Kunz, Niccolo Maschio, Christoph Siegenthaler

Patent number: 11351057Abstract: Certain aspects of the present disclosure provide a low friction trocar valve comprising a set of sheets arranged circularly and defining an entry point for the insertion of an instrument. In certain aspects, each sheet of the trocar valve's set of sheets comprises areas that overlap with two adjacent sheets. The trocar valve is formed in an opening of a valve housing coupled to or formed as part of a trocar cannula to provide a sealing mechanism for preventing the escape of pressurized fluids from the trocar cannula.Type: GrantFiled: September 5, 2019Date of Patent: June 7, 2022Assignee: Alcon Inc.Inventors: Niels Alexander Abt, Reto Grueebler, Timo Jung, Niccolo Maschio
