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.
