Optical coherence tomography (OCT) has transformed the clinical management of a myriad of ophthalmic conditions. Applying OCT to ophthalmic surgery may have implications for surgical decision-making and patient outcomes. To assess the feasibility and impact on surgical-decision making of microscope-integrated intraoperative OCT (iOCT) system. DISCOVER is an IRB-approved single-site multi-surgeon investigational device prospective consecutive case series. Participants included subjects undergoing ophthalmic surgery. Clinical characteristics were collected and iOCT imaging was obtained during surgical milestones as directed by the operating surgeon. A surgeon questionnaire was issued to each surgeon and completed after each case to evaluate the role of iOCT during surgery and its particular role in select surgical procedures. This report highlights the 1-year results (March 2014-February 2015) of the RESCAN 700 portion of the study. Percentage of cases with successful acquisition of iOCT imaging (i.e., feasibility). Percentage of cases that iOCT imaging altered surgical decision-making (i.e., utility) During year-1 of the DISCOVER study, 227 total eyes were enrolled (91 anterior segment cases and 136 posterior segment) to undergo imaging with the RESCAN 700 system. Successful imaging (e.g., the ability to acquire an OCT image of the tissue of interest) was obtained in 224 of 227 eyes (99%). During lamellar keratoplasty, the iOCT data provided information that altered surgeon decision-making in 38% of the cases (e.g., complete graft apposition when the surgeon believed there was interface fluid). In membrane peeling procedures, iOCT information was discordant with surgeon impression of membrane peel completeness in 19% of cases (e.g. lack of residual membrane, presence of occult membrane) impacting additional surgical maneuvers. The DISCOVER study demonstrates the feasibility of real-time iOCT with a microscope-integrated iOCT system for ophthalmic surgery. The information gained from iOCT appears to allow surgeons to assess subtle details in a unique perspective from standard en face visualization which can affect surgical decision-making some of the time, although the impact of these changes in decision-making on outcomes remains unknown. A prospective randomized masked trial is needed to confirm these results.
