摘要:
An ophthalmologic apparatus includes an OCT measurement unit (320), a corneal shape measurement unit (2231), an eyeball model generator (2234), and a site specifying unit (2235). The OCT measurement unit (320) is configured to acquire data of a subject's eye by deflecting measurement light using an optical scanner to project onto the subject's eye and detecting interference light between returning light of the measurement light from the subject's eye and reference light. The corneal shape measurement unit (2231) is configured to obtain curvature radius distribution on a cornea by detecting returning light of a measurement pattern projected onto a cornea of the subject's eye. The eyeball model generator (2234) is configured to generate an eyeball model using the curvature radius distribution on the cornea. The site specifying unit (2235) is configured to specify a traveling direction of the measurement light by performing ray tracing on the measurement light incident on each of a plurality of incident positions on the cornea based on a scan angle and the eyeball model, and to specify a position corresponding to an intraocular site of the subject's eye in the traveling direction based on the data acquired using the measurement light.
