Summary: | A microscope for ophthalmologic surgery according to an embodiment comprises: an optical system that photographs a patient's eye; a main body part that stores at least part of the optical system; an attachment that is attached to the main body part and has multiple bright points arranged in a ring; a determination part that determines whether the eyelids of the patient's eye are open or closed by determining whether or not bright point images are depicted within a prescribed region in the frame of a first image obtained by using the optical system to photograph the patient's eye while the multiple bright points are projected thereto; and a calculation part that calculates astigmatism information of the patient's eye based on a second image obtained by using the optical system to photograph the patient's eye while the multiple bright points are projected thereto. |
