摘要： An ophthalmological device according to the embodiments comprises an objective lens, a subjective inspection optical system, and an interference optical system. The subjective inspection optical system includes an optical element capable of correcting aberration of a subject's eye and projects a visual target onto the subject's eye via the objective lens and the optical element. The interference optical system splits light from a light source into reference light and measurement light, projects the measurement light onto the subject's eye via the objective lens and the optical element, generates interference light between returning light of the measurement light and the reference light, and detects the generated interference light.

摘要： An ophthalmic apparatus of an exemplary aspect performs the first and second OCT scans on a subject's eye. The first OCT scan is performed on the first region including the first site of the subject's eye, and the second OCT scan is performed on the second region including the second site. The ophthalmic apparatus acquires the first deviation information of the subject's eye prior to the first OCT scan and performs alignment, and also acquires the second deviation information of the subject's eye prior to the second OCT scan and performs alignment. The ophthalmic apparatus calculates the distance between the first site and the second site based on the first data acquired through the first OCT scan and second data acquired through the second OCT scan.

摘要： An ophthalmologic apparatus includes an objective lens, a refractive power measurement optical system, an inspection optical system, and an optical path separating unit. The refractive power measurement optical system is configured to project light in a first wavelength range onto a subject's eye via the objective lens and to detect returning light from the subject's eye. The inspection optical system is configured to project light in a second wavelength range onto the subject's eye via the objective lens. The optical path separating unit that is arranged in an optical path of the refractive power measurement optical system and is configured to separate an optical path of the inspection optical system from the optical path of the refractive power measurement optical system by performing wavelength separation based on changeable wavelength separation characteristics.

摘要： An ophthalmological device according to the embodiments comprises an objective lens, an objective measurement optical system, an interference optical system, and an image forming unit. The objective measurement optical system irradiates light onto a subject's eye via the objective lens and detects returning light from the subject's eye. The interference optical system splits light from a light source into reference light and measurement light, projects the measurement light onto the subject's eye via the objective lens so as to overlap at least part of an area of the irradiated light at the subject's eye by the objective measurement optical system, generates interference light between returning light of the measurement light and the reference light, and detects the generated interference light. The image forming unit forms a tomographic image of the subject's eye based on a detection result of the interference light by the interference optical system.
