Title:
OPHTHALMOLOGIC APPARATUS
Document Type and Number:
Japanese Patent JP2023171595
Kind Code:
A
Abstract:
To provide a novel technology to appropriately execute positioning between a device optical system for acquiring data on an eye to be examined and the eye to be examined.SOLUTION: An ophthalmologic apparatus includes: an anterior eye part observation system for guiding light from the anterior eye part of an eye to be examined to a light field camera; an optical system including an alignment optical system and a measuring system for optically acquiring data on the eye to be examined; a support part for supporting the face of a subject; a driving part for relatively moving the optical system and the support part; an analysis part for analyzing image data acquired by the light field camera; and a control part for controlling the driving part on the basis of a result of the analysis by the analysis part. The analysis part determines whether a bright point image based on the reflection light is detected in a single anterior eye part image in a predetermined reference image surface position acquired by the light field camera. The control part executes alignment control using the light field camera when the bright point image is not detected, or when an alignment signal corresponding to reflection light of alignment light from outside an optical axis of the anterior eye part observation system is not detected.SELECTED DRAWING: Figure 6
