Abstract: An ophthalmologic apparatus includes an acquisition unit and a controller. The acquisition unit includes an optical scanner capable of deflecting light in a predetermined deflection angle range. The acquisition unit is configured to acquire data of a subject's eye by performing A-scan on the subject's eye using optical coherence tomography by measurement light deflected by the optical scanner. The controller is configured to cause the acquisition unit to perform A-scan based on a deflection operation state of the optical scanner.

Abstract: An ophthalmic device that comprises a first objective lens system, an optical system, an anterior eye segment photographing system, and a first optical-path combining member. The first objective lens system includes two or more lenses. The optical system includes a projection system configured to project light onto a target eye via the first objective lens system. The anterior eye segment photographing system is used for photographing an anterior eye segment of the target eye. The first optical-path combining member is located between the two or more lenses to combine an optical path of the optical system and an optical path of the anterior eye segment photographing system.
