Ophthalmic observation apparatus, method of controlling the same, and recording medium

A method of controlling an ophthalmic observation apparatus including an optical system for generating a moving image of a subject's eye and a processor, the method comprising:

• causing the optical system to generate a moving image of the subject's eye into which an intraocular lens has been inserted;
• causing the processor to analyze a still image included in the moving image to identify a first site image corresponding to a predetermined site of the subject's eye and a second site image corresponding to a predetermined site of the intraocular lens;
• causing the processor to display, on a display device, the moving image, first position information that represents a position of the first site image, and second position information that represents a position of the second site image, wherein the predetermined site of the subject's eye is an eye center position, and the predetermined site of the intraocular lens is a center of the intraocular lens;
• displaying eye center position information that represents the eye center position as the first position information;
• displaying intraocular lens center position information that represents the center of the intraocular lens as the second position information;
• and
• displaying, based on the eye center position information and the intraocular lens center position, guide information for a user on the basis of a positional difference between the eye center position and the center of the intraocular lens.
