Standard preoperative OCT images were obtained. After vitrectomy, a predefined set of actions was performed using the iiOCT-based sensor. Images then were processed to assess the signal-to-noise ratio (SNR) at various angles to the retina and at different distances between the instrument tip and the retinal surface. Preoperative and intraoperative OCT images were compared qualitatively and quantitatively.<h4>Main outcomes measures</h4>The feasibOphthalmology science100085https://www.ebi.ac.uk/biostudies/studies/S-EPMC9560530biostudies-literatureClinical Evaluation of an Instrument-Integrated OCT-Based Distance Sensor for Robotic Vitreoretinal Surgery.PMC9560530van Romunde Sde Smet MDParrulli SCereda MGSchulz-Hildebrandt HDouven YGMKronreif GHuttmann GBeelen MFaridpooya KEixmann TfalseClinical Evaluation of an Instrument-Integrated OCT-Based Distance Sensor for Robotic Vitreoretinal Surgery.<h4>Purpose</h4>To assess the efficacy of an instrument-integrated OCT (iiOCT)-based distance sensor during robotic vitreoretinal surgery using the Preceyes Surgical System (PSS; Preceyes B.V.).<h4>Design</h4>Single-center interventional study.<h4>Participants</h4>Patients requiring vitreoretinal surgery.<h4>Methods</h4>Five patients were enrolled.
