    摘要： Systems and methods for capturing intraoperative biometry and/or refractive measurements include a sensor or valve associated with the eye and configured to detect a pressure of the eye. The system also includes an intra-op diagnostics device including a control unit arranged to actuate the intra-op diagnostics device to capture the intraoperative biometry and/or refractive measurements when the sensor or valve detects pressure within a predetermined pressure range.

    摘要： A system comprises first and second beamsplitter modules aligned along an alignment line. In certain embodiments, each beamsplitter module can split a beam traveling along a first optical path into a first split beam and a second split beam within a spectral range. Each beamsplitter module can transmit the first split beam along the first optical path and direct the second split beam along a second optical path substantially orthogonal to the first optical path and to the alignment line. In certain embodiments, each beamsplitter module can receive a first beam traveling along a first optical path and a second beam traveling along a second optical path that is substantially orthogonal to the first optical path and to the alignment line. Each beamsplitter module can combine the second beam with the first beam to yield a combined beam and transmit the combined beam along the first optical path.

    摘要： Systems and methods for determining a volume of the posterior segment of an eye during a fluid-to-gas exchange are described. The determined volume of the posterior segment may be used to determine the volume of pure tamponade gas to be introduced into the posterior segment resulting in a desired tamponade gas to other gas (e.g., air) ratio, such as during an ophthalmic surgical procedure. Particularly, the systems and methods may provide for improved gas utilization, less waste, and reduced surgery time, for example, by accurately measuring the volume of the posterior segment of the eye and only using the amount of pure gas required to produce the desired ratio. Further, in some implementations, mixing of a tamponade gas is accomplished intrinsically within the posterior segment of the eye, thereby avoiding manual mixing and reducing surgery time.

    摘要： Methods, systems, and software for controlling infusion pressure, such as during a medical procedure, using systemic blood pressure are described. Systemic blood pressure, such as brachial arm blood pressure or radial artery blood pressure, may be used to estimate central retinal artery blood pressure to estimate critical closing pressure. Further, the disclosure relates to controlling infusion pressure to prevent an increase in intraocular pressure above the estimated critical closing pressure when such is not desired, and, when such is desired, using systemic blood pressure and infusion pressure to control an intentional increase in intraocular pressure above the estimated critical closing pressure to stop intraocular bleeding.

    摘要： A drug introduction sleeve is disclosed that includes a selectively expandable body portion. The body portion is defined by a first open end and a second open end. A hollow interior is formed within the body portion. The body portion is selectively expandable from a first unexpanded configuration to a second expanded configuration whereby the volume of the hollow interior is increased when the body portion is expanded to the second expanded configuration, sufficient to temporarily retain a drug bolus.
