Ophthalmologic apparatus and method of controlling same
Abstract:
An ophthalmologic apparatus includes a refractive power measurement optical system, a fixation projection system, an inspection optical system, and a controller. The refractive power measurement optical system includes a first focusing element capable of changing a focal position, and is configured to project first light onto a subject's eye and to detect returning light of the first light from the subject's eye via the first focusing element. The fixation projection system is configured to project fixation light target onto the subject's eye. The inspection optical system includes a second focusing element capable of changing a focal position in conjunction with the first focusing element, and is used for a predetermined inspection in which second light is projected onto at least the subject's eye via the second focusing element. The controller is configured to control the first focusing element and the second focusing element based on a detection result of the returning light, and to perform refractive power measurement using the first light in a state of promoting a fogging of the subject's eye by controlling the fixation projection system after performing the predetermined inspection by inspection optical system.
