To compare the performance of the anterior segment forceps and anti-tremor training modules of the EYESi surgical simulator (VRmagic) by residents and experienced attending surgeons using the simulator for the first time.
Department of Ophthalmology, Mayo Clinic, Rochester, Minnesota, USA.
Twelve residents (4 per year) in the Mayo Clinic ophthalmology residency program and 3 experienced anterior segment surgeons participated. Each participant completed a total of 20 task trials on the EYESi forceps and anti-tremor level 4 training modules. Thus, the 15 participants completed a total of 300 task trials.
For the forceps module, experienced surgeons achieved significantly better total scores (P = .03), with lower total task time (P = .007) and instrument-in-eye time (P = .006) measurements. For the anti-tremor module, experienced surgeons achieved significantly better total scores (P = .02), with lower task time (P = .04) and instrument-in-eye time (P = .02) measurements. In addition, experienced surgeons performing the anti-tremor task had 76% more precise surgical outcomes as measured by the out-of-tolerance percentage (P = .03). All forceps and anti-tremor-measured parameters indicated significantly lower performance (P< .05) for the first 1 or 2 trials, with the exception of anti-tremor module incision stress, out-of-tolerance percentage, and average tremor values. Experienced surgeons had more consistent (lower variance) total scores on the forceps (P = .05) and anti-tremor (P = .03) training modules.
The EYESi surgical simulator anterior segment forceps and anti-tremor modules showed significant (P< .05) construct validity.
由住院医师和首次使用该模拟器的经验丰富的主治外科医生，比较EYESi手术模拟器（VRmagic）前段镊子和抗震颤训练模块的性能。
美国明尼苏达州罗切斯特市梅奥诊所眼科。
梅奥诊所眼科住院医师培训项目中的12名住院医师（每年4名）和3名经验丰富的前段外科医生参与。每位参与者在EYESi镊子和抗震颤4级训练模块上总共完成20次任务试验。因此，15名参与者总共完成了300次任务试验。
对于镊子模块，经验丰富的外科医生获得了显著更高的总分（P = .03），总任务时间（P = .007）和器械在眼内时间（P = .006）测量值更低。对于抗震颤模块，经验丰富的外科医生获得了显著更高的总分（P = .02），任务时间（P = .04）和器械在眼内时间（P = .02）测量值更低。此外，通过超出公差百分比衡量，经验丰富的外科医生执行抗震颤任务时手术结果的精确性高出76%（P = .03）。除抗震颤模块的切口应力、超出公差百分比和平均震颤值外，在前1或2次试验中，所有镊子和抗震颤测量参数均表明性能显著较低（P < .05）。经验丰富的外科医生在镊子（P = .05）和抗震颤（P = .03）训练模块上的总分更一致（方差更低）。
EYESi手术模拟器前段镊子和抗震颤模块显示出显著（P < .05）的结构效度。
