Abstract
An ophthalmic device includes a first light source configured to output first light, a second light source configured to output second light, a first interferometer configured to acquire a first tomographic image of a first range based on first interference light, a second interferometer configured to acquire a second tomographic image of a second range based on second interference light, and a controller. The controller may be configured to perform a specific scan on a subject eye that scans the first light and the second light simultaneously in a same plane, wherein the first tomographic image and the second tomographic image are obtained by performing the specific scan, calculate an amount of distortion of the first tomographic image, correct the first tomographic image based on the amount of distortion, and correct the second tomographic image based on the amount of distortion.
