Abstract: An ophthalmologic device includes: a visual target presenting unit configured to present a common visual target to be viewed with both subject's eyes; a presenting distance changing unit configured to change a presenting distance of the visual target presented by the visual target presenting unit from a predetermined far vision distance to a predetermined near vision distance; an ocular characteristic acquiring unit configured to objectively acquire an optical characteristic of the subject's eyes; an addition power adding unit configured to add the addition power to the both subject's eyes; and a control unit configured to cause the presenting distance changing unit to change the presenting distance and the ocular characteristic acquiring unit to continuously acquire the optical characteristic, in a state in which an addition power is added to the both subject's eyes by the addition power adding unit.

Abstract: An ophthalmic apparatus includes an objective lens arranged to be passed through by first and second measurement optical axes that are positioned at a distance from each other. An OCT optical system performs OCT on a subject's left eye arranged on the first measurement optical axis or a subject's right eye arranged on the second measurement optical axis. An optical axis adjusting unit adjusts an optical axis of the OCT optical system under control of a controller so that the optical axis approximately coincides with any one of the first measurement optical axis and the second measurement optical axis. An intraocular parameter calculator calculates an intraocular parameter of the subject's left or right eye based on a detection result of interference light acquired in a state where the optical axis of the OCT optical system approximately coincides with the first or second measurement optical axis.

Abstract: An ophthalmic apparatus includes an objective lens, and an OCT optical system optical system is configured to project a measurement light onto a subject's left or right eye via an objective lens, and to detect interference light between returning light of the measurement light a reference light having traveled through a reference optical path. An optical axis switching member switches an optical axis of the OCT optical system to approximately coincide with a first or second measurement optical axis. A controller is configured to control the optical axis switching member. An intraocular parameter calculator calculates an intraocular parameter of the subject's left or right eye based on a detection result of the interference light acquired in a state where the optical axis of the OCT optical system is switched so that the optical axis of the OCT optical system approximately coincides with the first or second measurement optical axis.
