Abstract: An illumination system of the ophthalmological device of an exemplary embodiment projects illumination light that has been outputted from a light source onto an anterior eye part of an examined eye. An interference photography system photographs an interference pattern that is formed on the cornea by the illumination light. An anterior eye part photography system photographs the anterior eye part onto which the illumination light is being projected. A first optical path coupling element couples the optical path of the interference photography system and the optical path of the anterior eye part photography system. A control part aligns an observation interference image that is at least a portion of an interference image that has been acquired by the interference photography system and an anterior eye part image that has been acquired by the anterior eye part photography system and makes a display device display the aligned images. The control part also makes the display device display observation location information that indicates the location of the observation interference image on the anterior eye part image.

Abstract: This ophthalmic information processing device includes an acquisition unit and a normalization unit. The acquisition unit acquires eye shape data or an intraocular distance of an eye of a subject. The normalization unit normalizes the eye shape data or the intraocular distance on the basis of body data of the subject or the degree of refraction of the eye of the subject.

Abstract: An ophthalmological observation device (1) according to an exemplary embodiment comprises moving image generation units (30, 40), an analysis unit (211), and a display control unit (200). The moving image generation units image a subject eye having an artificial object inserted therein to generate a moving image. The analysis unit analyzes a still image included in the moving image generated by the moving image generation units, and specifies a first site image corresponding to a predetermined site of the subject eye and a second site image corresponding to a predetermined site of the artificial object. The display control unit causes a display device (3) to display the moving image generated by the moving image generation units, first position information indicating the position of the first site image specified by the analysis unit, and second position information indicating the position of the second site image specified by the analysis unit.

Abstract: This ophthalmic device includes an acquisition unit, an OCT unit, an analysis unit, and an estimation unit. The acquisition unit acquires the degree of refraction of a first region that includes the fovea of an eye being examined. The OCT unit acquires OCT data for the fundus of the eye using optical coherence tomography. The analysis unit identifies the shape of the fundus by analyzing the OCT data. The estimation unit estimates the degree of refraction of the region of the fundus surrounding the first region on the basis of the degree of refraction of the first region and the shape of the fundus.

Abstract: An ophthalmological observation device (1) according to an exemplary embodiment of the present invention comprises a moving image generation unit (30, 40), an analysis unit (211), a target location determination unit (212), and a display control unit (200). The moving image generation unit images a subject eye to generate a moving image. The analysis unit analyzes a still image, which is included in the moving image generated by the moving image generation unit, so as to detect an image of a given site in the subject eye. The target location determination unit determines a target location for a predetermined treatment at least on the basis of the image of the given site which has been detected by the analysis unit. The display control unit displays, on a display device (3), the moving image which has been generated by the moving image generation unit and target location information which indicates the target location determined by the target location determination unit.

Abstract: An ophthalmologic observation device (1) according to an exemplary embodiment comprises a microscope (10), processors (203, 211), and a display control unit (201). The microscope includes a pair of imaging systems and a pair of pieces of video data of a to-be-inspected eye. The processor executes first processing so that a predetermined parameter of the pair of pieces of video data satisfies a first condition. The first processing includes at least one among control of the microscope and image processing on at least one of the pair of pieces of video data. The display control unit causes a display device (3) to display a pair of images on the basis of the pair of pieces of video data obtained through the first processing.
