摘要： In certain embodiments, a corneal implant includes a transparent dome and a ring. The transparent dome has a circular base with a perimeter that has a diameter of less than 2 centimeters. The transparent dome comprises a transparent biocompatible material. The ring has an annular shape and is disposed about the perimeter of the circular base of the transparent dome. The ring comprises a biocompatible material with a surface. The peripheral portion of the surface forms openings that facilitate attachment of eye tissue to the ring. Each opening has a diameter of less than 2 millimeters.

摘要： 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.

摘要： Certain embodiments provide a surgical instrument comprising surgical instrument comprising an device having a functional end and a main handle comprising a distal end coupled to the device. The surgical instrument further comprises an actuation handle insert comprising a number of first rolling components and an actuation tube coupled to the actuation handle insert, wherein the functional end of the device at least partially extends outside of the actuation tube when the device is deactivated. The surgical instrument further comprises levers comprising second rolling components. The surgical instrument further comprises a plurality of rolling elements, wherein each of the rolling elements is placed between one of the second rolling components and one of the first rolling components and pressing one or more of the levers pushes the actuation handle insert forward relative to the device, causing the actuation tube to transition the device from the deactivated state to an activated state.

摘要： 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.

摘要： 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.
