Abstract
Purpose: To investigate the correlation in performance of cataract surgery between a virtualreality simulator and real-life surgery using two validated, objective assessment tools.Methods: Cataract surgeons with varying levels of experience were included in the study. All participants performed and video-recorded three standard cataract surgeries before completing a proficiency-based test on the EyeSi virtual-reality simulator. Standard cataract surgeries were defined as: 1) surgery performed under local anaesthesia, 2) patient age > 60 years, and 3) visual acuity > 1/60 pre-operatively. A motion-tracking score was calculated by multiplying average path length and average number of movements from the three real-life surgical videos of full procedures. The EyeSi test consisted of five abstract and two procedural modules: intracapsular navigation, antitremor training, intracapsular antitremor training, forceps training, bimanual training, capsulorhexis, and phaco divide and conquer. Results: Eleven surgeons were enrolled. After a designated warm-up period, the proficiency-based test on the EyeSi simulator was strongly correlated to real-life performance measured by motion-tracking software of cataract surgical videos with a Pearson correlation coefficient of -0.70(p=0.017). Conclusion: Performance on the EyeSi simulator is significantly and highly correlated to real-life surgical performance. However, it is recommended that performance assessments are made using multiple data sources.
