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 invention relates to an Illumination and observation system (1), in particular for an ophthalmic microscope. The system comprises a first observation pupil (4) and a second observation pupil (5) for the eyes of an observer such as an assistant. Further, the system comprises a coaxial illumination (6) in the first observation pupil (4) and a main illumination (7), the coaxial illumination (6) being adapted to generate a red reflex (13) in the observed eye in operation and the main illumination having a larger field of illumination than the coaxial illumination (6, 10, 11).
