Significant integrative advances are needed for intraoperative optical coherence tomography (iOCT) to achieve widespread use across ophthalmic surgery. A surgeon feedback system that provides microscope integration, heads-up display and foot pedal control of the OCT scan location represents a major interval advance in ophthalmic surgery. In this report, we describe the preliminary findings of the Determination of feasibility of Intraoperative Spectral domain microscope Combined/integrated OCT Visualisation during En face Retinal and ophthalmic surgery (DISCOVER) study, a multisurgeon investigational device study examining the role of microscope integrated iOCT systems with surgeon heads-up display feedback (eg, Carl Zeiss Meditec RESCAN 700, Cole Eye Institute iOCT prototype). During surgical manoeuvres in anterior segment and posterior segment surgery, this technology provides rapid visualisation of the area of interest and provides the surgeon with information regarding instrument–tissue interactions. This system represents a major advance in iterative technology for iOCT and may provide the first widely available platform for surgeons to seamlessly assimilate this technology into the operating room theatre.
