A surgical microscope system (100) for ophthalmology, in particular for cataract surgery, is proposed, which comprises an illumination unit (10) and a viewing unit (30), the surgical microscope system (100) being set up to irradiate illumination light (15) of the illumination unit (10) into an eye (50) arranged on the objective side of the surgical microscope, the surgical microscope system (100) comprising a detection unit (20) by means of which a scattering (15′) of the illumination light (15) irradiated into the eye (50) is determinable, in the form of a scattering pattern and/or scattering coefficient, by sensing a portion of the illumination light (15) radiated back by the eye (50).
