Patent ID: 11684252

Abstract:
An ophthalmologic apparatus includes an optical scanner, an interference optical system, an intraocular distance calculator, an image correcting unit, and a controller. The optical scanner is disposed at an optically substantially conjugate position with a first site of a subject's eye. The interference optical system is configured to split light from a light source into reference light and measurement light, to project the measurement light onto the subject's eye via the optical scanner, and to detect interference light between returning light of the light from the subject's eye and the reference light via the optical scanner. The image forming unit is configured to form a tomographic image of the subject's eye corresponding a first traveling direction of the measurement light deflected by the optical scanner, based on a detection result of the interference light. The intraocular distance calculator is configured to obtain an intraocular distance between predetermined sites of the subject's eye based on the detection result of the interference light. The image correcting unit is configured to correct the tomographic image based on the intraocular distance. The controller is configured to control at least the optical scanner.
