Operation microscope with fixation device |
摘要 |
The invention contemplates an operation microscope which incorporates an eye-fixation feature to enable a patient's eye (under microscope observation) to precisely maintain infinity focus and viewing alignment, either with the central axis of the microscope or at desired controllable offset therefrom. Embodiments are shown for incorporation of this feature both as part of the field-illumination optical system associated with the microscope, and otherwise, but nevertheless also utilizing part of the observational optical system of the microscope.
