Intraoperative optical coherence tomography using the RESCAN 700: preliminary results from the DISCOVER study

TLDR

Widespread use of intraoperative OCT in ophthalmic surgery requires integrative advances, such as microscope‑integrated systems with heads‑up displays and foot‑pedal control that enable real‑time feedback during surgery. The study reports preliminary findings on the feasibility of microscope‑integrated iOCT with heads‑up display feedback during retinal and ophthalmic surgery. The integrated iOCT system delivers rapid visualization of the surgical field and real‑time information on instrument–tissue interactions during anterior and posterior segment procedures. The system constitutes a major technological advance and may become the first widely available platform enabling surgeons to seamlessly integrate iOCT into the operating room.

Abstract

Significant integrative advances are needed for intraoperative optical coherence tomography (<i>i</i>OCT) 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 <i>i</i>OCT systems with surgeon heads-up display feedback (eg, Carl Zeiss Meditec RESCAN 700, Cole Eye Institute <i>i</i>OCT 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 <i>i</i>OCT and may provide the first widely available platform for surgeons to seamlessly assimilate this technology into the operating room theatre.
