    摘要： An IOP control device for implantation in an eye of a patient is disclosed, including a housing with an entrance port and an exit port, a membrane anchored within the housing in a manner forming a flow control chamber on a first side of the membrane and a fluid flow passageway on a second opposing side of the membrane, and a position sensor system. The flow control chamber is arranged to contain a gas creating a flow control chamber pressure, and the membrane is configured to affect flow through the fluid flow passageway from the entrance port to the exit port by deflecting in response to changes in the flow control chamber pressure. The position sensor system includes a first conductive portion and a second conductive portion positioned to selectively contact the first conductive portion to indicate the position of the membrane relative to the fluid flow passageway.

    摘要： An infusion sleeve has a flexible tube enclosing a lumen. The tube has a plurality of wall segments, each wall segment located between the lumen and an exterior surface of the tube and extending parallel to a central axis of the tube. The plurality of wall segments includes at least two thick wall segments and at least two thin wall segments alternately arranged such that each thick wall segment is adjacent to two thin wall segments, and each thin wall segment is adjacent to two thick wall segments.

    摘要： Systems and methods for intraocular lens selection include receiving, by one or more computing devices implementing a prediction engine, pre-operative multi-dimensional images of an eye; extracting, by the prediction engine, pre-operative measurements of the eye based on the pre-operative images; estimating, by the prediction engine using a prediction model based on a machine learning strategy, a post-operative position of an intraocular lens based on the extracted pre-operative measurements; selecting a power of the intraocular lens based on the estimated post-operative position of the intraocular lens; and selecting the intraocular lens based on the selected power. In some embodiments, the systems and methods further include receiving post-operative multi-dimensional images of the eye after implantation of the selected intraocular lens, extracting post-operative measurements of the eye, and updating the prediction model based on the pre-operative measurements and the post-operative measurements.

    摘要： An optical surgical probe includes a handpiece, a light guide within the handpiece, and a multi-spot generator at a distal end of the handpiece. The handpiece is configured to optically couple to a light source. The light guide is configured to carry a light beam from the light source to a distal end of the handpiece. The multi-spot generator includes a faceted optical element with a faceted end surface spaced from a distal end of the light guide. The faceted end surface includes at least one facet oblique to a path of the light beam.
