An ophthalmic visualization system can include a computing device in communication with an OCT system configured to scan a surgical field to generate an OCT image. The computing device can be configured to determine locations within the surgical field corresponding to locations within the OCT image. The ophthalmic visualization system can also include an indicator mechanism in communication with the computing device and a surgical microscope configured to image the surgical field. The indicator mechanism can be configured to cause a location indicator to be positioned within a field of view of the surgical microscope. The location indicator can graphically represent the locations within the surgical field corresponding to the locations within the OCT image.
