1. An ophthalmic imaging apparatus comprising: a measurement unit configured to acquire a data set by applying optical coherence tomography to a three-dimensional region of a subject's eye including an area extending from an anterior surface of a cornea to a surface of a retina; an eye model generation unit configured to acquire values of one or more parameters of the subject's eye by analyzing the data set acquired by the measurement unit, and to generate a three-dimensional eye model based on the values acquired; and a simulation execution unit configured to execute a simulation based on the three-dimensional eye model generated by the eye model generation unit; wherein the measurement unit comprises: an optical system configured to split first light output from a highly depth reachable light source into measurement light and reference light, and to detect interference light generated by superposing the measurement light returning from the subject's eye on the reference light; and an image data generation unit configured to acquire a plurality of reflection intensity profiles extending from a front surface to a rear surface of the three-dimensional region based on a result of detection of the interference light by the optical system, and to generate image data of the three-dimensional region as the data set based on the plurality of reflection intensity profiles acquired.
