Abstract
PURPOSE: This study is a secondary analysis of the IDOSP trial published in the Annals of Surgery 2020. The aim of this study was to examine the influence of stereo acuity on surgical performance in a laparoscopic training parkour with 3D- versus 4 K-2D-display technique. METHODS: The surgical performance of medical students (MS), non-board-certified surgeons (NBC), and board-certified surgeons (BC) was compared using 3D- versus 4 K-2D-display technique at a training parkour in a randomized cross-over trial. Stereo acuity was tested by TNO and Titmus Stereo tests. RESULTS: Eighty-nine participants were included in this sub-trial. The median stereo acuity for all participants, measured with the Titmus test, was 25 s arc, with TNO test 30 s arc. Higher quality stereo vision, measured with the Titmus test, correlated significantly with a reduced parkour time (r = 0.26, p = 0.02) and error (r = 0.21, p = 0.048) with the 3D screen. The TNO test did not correlate significantly with parkour performance. There was no statistically significant correlation between parkour time nor error and stereo acuity using the 4 K system (p > 0.457 respectively). Higher age showed a significant correlation with lower stereo acuity measured with TNO (r = 0.21, p = 0.014), but not with the Titmus test (r = - 0.7, p = 0.39). Seven percent of the group "NBC and BC" showed reduced stereo acuity > 120 s arc with the Titmus test and 3% with the TNO test. CONCLUSION: High-quality stereo vision is of utmost importance for surgical skills using a 3D-display system. This was most obvious for MS and for tasks that place particularly high demands on hand-eye coordination. The Titmus test was more precise than the TNO test to predict the benefit of a 3D monitor system. Experience and fine motor skills could partly compensate for a poorer stereo acuity. TRIAL REGISTRATION: This trial was registered at clinicaltrials.gov (trial number: NCT03445429, registered February 26, 2018).
