To determine the effect of distraction on anterior segment surgical performance using a virtual reality simulator in expert and novice surgeons.
Horizon Suite Simulation Centre, South Devon Foundation NHS Trust, Devon, England.
Cohort study.
Expert and novice ophthalmic surgeons completed a standardized and validated surgical task 10 times on a virtual reality simulator (EyeSi). They then completed a cognitive task (arithmetic questions), after which they completed 10 attempts on the simulator module while also completing the cognitive task.
For experts (n = 7), the distracting cognitive task had no statistically significant effect on operating scores. The rate of correctly answered questions decreased from 12.3 per minute ± 2.1 (SD) while single tasking to 8.6 ± 3.1 per minute while dual tasking (P=.018). For novices (n = 14), the distracting cognitive task had no effect on any operating score except a small reduction in the penalty odometer score. The rate of correctly answered questions decreased from 11.5 ± 4.1 per minute while single tasking to 7.0 ± 3.2 per minute while dual tasking (P=.001).
A distractive cognitive task reduced the ability of novice surgeons and expert surgeons to deal with that cognitive task, although their simulated surgical performance was not overtly compromised.

队列研究。
眼科专家和新手外科医生在虚拟现实模拟器（EyeSi）上完成了 10 次标准化和验证过的手术任务。然后，他们完成了一项认知任务（算术题），之后在模拟器模块上完成了 10 次尝试，同时也完成了认知任务。
对于专家（n = 7），分散注意力的认知任务对操作评分没有统计学上的显著影响。正确回答问题的速度从每分钟 12.3 ± 2.1（SD）下降到每分钟 8.6 ± 3.1，同时进行双重任务（P =.018）。对于新手（n = 14），除了罚时里程表得分略有下降外，分散注意力的认知任务对任何操作评分都没有影响。正确回答问题的速度从每分钟 11.5 ± 4.1 下降到每分钟 7.0 ± 3.2，同时进行双重任务（P =.001）。
分散注意力的认知任务降低了新手外科医生和专家外科医生处理该认知任务的能力，尽管他们的模拟手术表现没有明显受到影响。
