This study aimed to examine the impact of surgical timing on the performance of vitreoretinal (VR) trainees in a simulated setting.
In a prospective cross-over observational study, VR trainees were asked to perform various surgical tasks on the Eyesi surgical simulator. These included navigation and anti-tremor, pars plana vitrectomy and posterior vitreous detachment, bimanual training, bimanual scissors use, and epiretinal membrane peeling. The trainees were randomly assigned to Group A (performed tasks during morning hours) and Group B (performed tasks during evening hours). After completing assigned tasks, the trainees were asked to cross over to the other group. Primary outcome measures were objective scores and time to perform each surgical maneuver in both groups. Secondary outcome measures included subjective scores given by each trainee and complications encountered.
Eight VR trainees, three males (37.5%) and five females (62.5%), were included in the study. The mean objective score obtained after performing various surgical tasks was similar in both groups. The time taken to complete the above tasks was identical. Though the complications were more in the evening than in the morning, the difference was not statistically significant. Subjectively, residents did not find any difference in either group.
The timing of VR surgery does not alter the surgical performance in a simulator setting. While objective measures showed no significant difference, complications trended higher in the evening.
本研究旨在检验手术时间对玻璃体视网膜（VR）培训学员在模拟环境中操作表现的影响。
在一项前瞻性交叉观察研究中，要求VR培训学员在Eysi手术模拟器上执行各种手术任务。这些任务包括导航和抗震颤、玻璃体切割术和平坦部玻璃体切除术、双手操作训练、双手使用剪刀以及视网膜前膜剥离。培训学员被随机分为A组（在上午执行任务）和B组（在晚上执行任务）。完成指定任务后，要求培训学员交叉到另一组。主要观察指标是两组中每项手术操作的客观评分和执行时间。次要观察指标包括每位培训学员给出的主观评分和遇到的并发症。
本研究纳入了8名VR培训学员，其中3名男性（37.5%）和5名女性（62.5%）。在执行各种手术任务后获得的平均客观评分在两组中相似。完成上述任务所需的时间相同。虽然晚上的并发症比早上多，但差异无统计学意义。主观上，住院医师在两组中均未发现任何差异。
VR手术的时间安排不会改变模拟器环境中的手术表现。虽然客观指标显示无显著差异，但并发症在晚上有更高的趋势。
