Binocular en face OCT imaging during ophthalmic surgery may be performed with an OCT scanning controller that interfaces to an OCT scanner used with a surgical microscope. The OCT scanner may generate left and right sample beams, and receive left and right measurement beams, respectively, to generate left and right scan data. The OCT scanning controller may process the left and right scan data to generate left and right en face images for respective viewing from binoculars in the surgical microscope to obtain an intraoperative stereoscopic en face view of interior portions of the eye.
