The invention relates to a stereoscopic microscope, which is suited both for pure observation and also for support during surgical procedures in ophthalmology. It can be adapted to both uses through an inversion optics arrangement, which can be removed from the beam path of the microscope. The inversion optics arrangement is arranged in an attachment containing a field-magnifying lens, which attachment is needed in most cases, and is located between the field-magnifying lens and the objective lens of the microscope such that it is movable within the attachment. Thus, the field-magnifying lens does not need to be moved in the case of sight defects of a patient, but the correction is carried out with the inversion optics arrangement, and this means an inside focussing occurs. The inversion optics arrangement can also be removed with the attachment so that the microscope can then be used as a normal viewing microscope. In place of the field-magnifying lens, it is also possible to provide a prism system for the image inversion.
