Systematic article exploration using the PRISMA 2020 Flow Diagram. Initially, to identify potential studies, we input the keywords ((‘intraoperative OCT’) OR (iOCT)) AND (retina*)) into four databases: PubMed, Embase, Web of Science, and the Cochrane Library. This search yielded 429 research candidates. Next, to screen these articles, we conducted checks for duplication, abstract availability, language, and article type. Furthermore, we screened each study according to the following criteria: 1) original articles, 2) written in English, 3) iOCT is the main research topic, 4) more than 10 cases, 5) clinical research, and 6) qualitative descriptions presenting the utility and/or technical issues of the iOCT. In total, 48 articles were screened based on title and abstract. Ultimately, 15 studies were deemed eligible for inclusion after a detailed eligibility assessment
