  • Patent number: 10932665
    Abstract: An illumination system of an ophthalmologic microscope system projects illumination light onto a patient's eye. A light receiving system guides returning light of the illumination light to an image sensor. A display controller controls a display device to display an image obtained by the image sensor. A magnification changing unit changes display magnification of the image. An interference optical system detects interference light generated from returning light of measurement light from the eye and reference light. An optical scanner is used to scan the eye with the measurement light. An OCT data generation unit processes a detection result of the interference light to generate data. A condition setting unit sets a projection condition of the measurement light in accordance with change in the display magnification. An OCT controller controls the interference optical system and/or the optical scanner based on the projection condition.

  • Patent number: 10758123
    Abstract: An ophthalmological microscope system, having an illumination system that projects illumination light onto a subject's eye. A light receiving system guides returning light of the illumination light to an image sensor or an eyepiece system. An interference optical system splits light into measurement light and reference light and detects interference light generated from returning light of the measurement light and the reference light. A designation unit is used for designating an operation mode. When an observation priority mode (or an OCT priority mode) has been designated, a controller executes first light amount control that restricts light amount of the measurement light (or second light amount control that restricts light amount of the illumination light) to make total light amount of the illumination light and the measurement light equal to or less than a predetermined value.

  • Patent number: 10692392
    Abstract: A display apparatus includes a display, a display controller, a sensor, and a work identifying unit. The display controller causes the display to continuously display a guidance video. The guidance video indicates a specified work procedure of respective processes. The display controller analyzes a work procedure that has been actually performed by the operator from a time series of the respective works identified by the work identifying unit, compares the analyzed work procedure with the process sequence and the specified work procedure, and returns to the process including an unprocessed work that has not been performed in accordance with the process sequence and the specified work procedure to cause the display to redisplay the guidance video indicating the work procedure of the returned process when having determined that the work performed by the operator is not performed in accordance with the process sequence and the specified work procedure.
