Core Tip	This large retrospective cohort study evaluates whether surgical start time influences intraoperative complication rates in cataract surgery. Analyzing over 32000 cases, we found no significant variation in complication rates across the surgical day. These findings challenge assumptions that surgeon fatigue or time of day meaningfully impact surgical performance within standard operating hours. By isolating surgeon-related factors in a high-volume, standardized procedure, this study provides robust evidence supporting current scheduling practices and highlights the need to investigate alternative contributors to surgical error.
