Abstract

Background: In recent years, an increasing number of surgical microscopes fitted with an OCT module (intraoperative OCT, iOCT) have become available, providing high-resolution images of the surgical site in real time. While a 2018 survey at our hospital showed that iOCT delivered an additional intraoperative benefit in only 2.4% of all operations, considering that the manufacturer had since revised the hardware and software, we conducted a second user evaluation of this technology.<br />Material and Methods: Prospective monocentric analysis of the application and user-friendliness of an EnFocus Ultra-Deep OCT (Leica Microsystems) over a period of 25 (2018) and 20 working days (2021). A standardized questionnaire was used to assess the surgeons' use of iOCT and its influence on the surgical course.<br />Results: 118 operations were performed over a 25-day period in 2018 and 92 operations were performed over a 20-day period in 2021. In 2018, iOCT was used in 24.6% and in 2021 in 48.9% of all surgeries, with iOCT proving to be "critical" to the surgical course in 2.4% and 3.3% of cases, respectively, as assessed by the surgeons in both years. These were operations in which the intraocular view was limited, e.g., with decompensated cornea, vitreous hemorrhage, or after previous surgery, e.g., after penetrating keratoplasty.<br />Conclusion: Further development of the user interface led to an improvement in usability, and the iOCT was used significantly more often. In both years, the iOCT proved to be critical for the course of the surgery in a comparably small number of operations, especially those involving complex situations.<br />Competing Interests: GG: Leica Microsystems, die anderen Autoren und Autorinnen geben keine Interessenkonflikte an./GG: Leica Microsystems, the other authors declare that they have no conflict of interest.<br /> (Thieme.
