ABSTRACT:
An operation microscope in which the optical axis of the illumination optical system is in alignment with the optical axis of the objective lens of the observation optical system and the illumination rays pass along the optical axis of the objective lens. Due to this construction, it is possible to sufficiently illuminate the deep parts of diseased tissue in, for example, a cataract operation, and very easy to confirm whether or not any part of the lens remains in the capsula lentis after the removal of the lens of the eye.
