Abstract:
An ophthalmological apparatus comprising:a main unit section having a movable optical system housing which houses an optical system for shooting or examining an eye to be examined; a manual operation unit manually positioning the main unit section; an alignment chart projection unit projecting onto the eye an chart luminous flux for alignment; a chart detection unit detecting the reflected luminous flux of the chart luminous flux reflected on the eye; an alignment unit actuating the optical system housing on the basis of a detection result of the chart detection unit in a case where the main unit section is positioned by the manual operation unit so that the chart detection unit detects the reflected luminous flux, such as to move the optical system housing with respect to the main unit section; a position information detection unit detecting information about variations in position of the main unit section caused by the manual operation unit during the operation of the chart detection unit; and a correction unit correcting the actuating amount of the optical system housing on the basis of a detection result of the position information detection unit.
