Abstract
For improving the operability of the apparatus, the ophthalmologic apparatus of the invention includes a measuring optical system which optically measures an eye to be examined, a detection system which detects alignment information of the eye for the measurement, a driving mechanism which moves the measuring optical system relative to the eye, an operating device which allows an operator to manually control the driving mechanism in order to move the measuring optical system, and a controller that controls the driving mechanism to perform alignment of the measuring optical system with respect to the eye, in a plurality of modes including a first mode executing automatic alignment within a predetermined range based on the alignment information of the detection system and a second mode executing manual alignment within a range broader than the predetermined range based on the operation of the operation device, wherein the controller automatically changes its operation between the first mode and the second mode based on a predetermined event.
