Abstract
An ophthalmic surgical microscope system (100) includes a surgical microscope (101). The surgical microscope (101) is accommodated on a carrier unit (109) so as to be adjustable in elevation in order to be able to adjust a work distance (124) between the surgical microscope (101) and a patient eye (120). A first drive (112) is provided for adjusting the elevation of the surgical microscope (101). The ophthalmic surgical microscope system (100) includes an ophthalmic ancillary module (114) having an adjustable ophthalmic magnifier lens (116). The work distance (125) between the ophthalmic magnifier lens (116) and the patient eye (120) can be adjusted with a second drive (117). A drive coupling (123) is provided which couples the first drive for adjusting elevation of the surgical microscope (101) to the second drive (117) for adjusting the ophthalmic magnifier lens (116).
