Patent number: 10045693Abstract: An ophthalmologic observation apparatus of an embodiment includes a photographing optical system, measuring optical system, optical-path coupler, first and second drivers and controller. The photographing optical system includes a first focusing lens and performs photography for acquiring a front image of an eye. The measuring optical system includes a second focusing lens and performs OCT for acquiring a cross-sectional image of the eye. The optical-path coupler couples optical paths of the photographing optical system and measuring optical system at a location on the eye side than the first and second focusing lenses. The first driver moves the first focusing lens along an optical axis of the photographing optical system. The second driver moves the second focusing lens along an optical axis of the measuring optical system. The controller controls the first and second drivers individually.Type: GrantFiled: September 12, 2013Date of Patent: August 14, 2018Assignee: KABUSHIKI KAISHA TOPCONInventors: Ryuichi Morishima, Kohta Fujii

Patent number: 9980643Abstract: An ophthalmologic apparatus which is capable of preferably executing position matching between an eye and optical system is provided. An ophthalmologic apparatus of an embodiment includes an examination optical system, supporting part, driver, two or more imaging parts, analyzer and controller. The examination optical system is used for an examination of the eye. The supporting part supports a face of a subject. The driver moves the examination optical system and the supporting part relatively and three-dimensionally. The two or more imaging parts substantially simultaneously photograph an anterior eye part of the eye from different directions. The analyzer obtains a three-dimensional position of the eye by analyzing two or more photograph images acquired by the two or more imaging parts substantially simultaneously. The controller controls the driver based on the three-dimensional position to relatively move the examination optical system and the supporting part.Type: GrantFiled: August 10, 2016Date of Patent: May 29, 2018Assignee: KABUSHIKI KAISHA TOPCONInventors: Takashi Fujimura, Taisaku Kogawa, Ryuichi Morishima, Hiroaki Okada, Takefumi Hayashi
