  • Patent number: 10456035
    Abstract: An ophthalmic surgical microscope includes an observation optical system configured to guide observation luminous fluxes for a right eye and a left eye from an observation object to an imaging device, an actuator configured to move a position of the observation optical system in at least a direction intersecting with the observation luminous fluxes, a processor, and a memory storing computer-readable instructions. The computer readable instructions, when executed by the processor, cause the ophthalmic surgical microscope to cause a stereoscopic image display to display an observation image to be observed with a right eye of a user and an observation image to be observed with a left eye of the user, detect a position of the observation object with respect to the observation optical system, and correct a deviation in a relative position of the observation optical system with respect to the observation object.

  • Patent number: 10010451
    Abstract: An ophthalmic laser surgical apparatus includes an XY scan unit, a light guiding optical element, an objective lens, and a Z scan unit. The XY scan unit includes a deflecting device for deflecting the pulsed laser beam, and scans the pulsed laser beam in a direction crossing an optical axis. The light guiding optical element is provided downstream of the deflecting device on the optical path of the pulsed laser beam. The light guiding optical element has refractive power, and guides the pulsed laser beam. The objective lens causes the pulsed laser beam through the XY scan unit and the light guiding optical element to converge in a tissue of a patient's eye. The Z scan unit varies the optical path length between the light guiding optical element and the objective lens while the objective lens is fixed in position on the optical path.

  • Patent number: 9930184
    Abstract: Slave device information transmitting unit of the present invention transmits slave device information to a mobile phone. Slave device transfer data receiving unit receives slave device transfer data from the mobile phone, and stores the slave device transfer data in storage unit. Destination slave device determining unit extracts destination slave device information from slave device transfer data stored in storage unit, and selects a cordless telephone slave device which is a destination of the slave device transfer data, based on destination slave device identification information which is set in the destination slave device information. Slave device transfer data transmitting unit transmits slave device transfer data to a cordless telephone slave device selected by destination slave device determining unit.

  • Patent number: 9615971
    Abstract: An ophthalmic laser surgery apparatus for treating an eye of a patient includes: a laser light source configured to emit the pulse laser light; an objective lens configured to condense the pulse laser light emitted from the laser light source on the tissue to cause a photodistuption of the tissue; a scanner configured to scan a condensing position of the pulse laser light condensed by the objective lens; and a controller configured to control the scanner to adjust speed of scanning the condensing position depending on a size of the photodisruption which fluctuates in according to an aberration which fluctuates according to a change in the condensing position.
