Four-dimensional microscope integrated optical coherence tomography (4D-miOCT) has been proposed as an alternative to conventional white-light microscopy during ophthalmic surgical interventions. Its real-time visualization capability of 3D data constitutes one of the most promising visualization techniques for many surgical use cases in ophthalmology. In this work, we conducted a comprehensive user study for optimal visualization with the highest performance use of the 4D-miOCT data, comparing an autostereoscopic light field tablet to a 3D TV. With the feedback collected as part of a user study, we are able to further optimize how we display 4D-miOCT data to surgeons.
