Provided is an ophthalmic surgical microscope in which a drive system for moving optical members can be positioned with a high degree of freedom, and with which a patient's eye can be observed and OCT images can be captured. An ophthalmic surgical microscope according to an embodiment includes an illumination optical system, an observation optical system, an interference optical system, an optical scanner, a collimator lens, an optical fiber, and a movement mechanism. The illumination optical system illuminates the patient's eye using illumination light. The observation optical system is used in order to observe the patient's eye that is illuminated by the illumination optical system. The interference optical system separates light from a light source into measurement light and reference light, and detects the interference light between the reference light and the returned light of the measurement light from the patient's eye. The optical scanner is disposed on the optical path of the measurement light. The collimator lens is disposed between the light source and the optical scanner. The exit end of the measurement light from the optical fiber is disposed at a position facing the collimator lens. The movement mechanism moves the collimator lens and the exit end relative to one another along the optical path of the measurement light. |
