PURPOSE
To compare the performance on the EYESi surgical simulator capsulorhexis training module between medical students and residents and experienced cataract surgeons.
SETTING
Department of Ophthalmology, University of Iowa, Iowa City, Iowa, USA.
DESIGN
Comparative case series.
METHODS
The study comprised medical students and residents at the University of Iowa and experienced cataract surgeons. Neither group had experience with the simulator. Each participant completed 4 trials on the capsulorhexis module.
RESULTS
The 7 experienced surgeons achieved statistically significantly better total scores than the 16 medical students and residents on the easy level and the medium level of the capsulorhexis module (P = .004 and P = .000007, respectively). Experienced surgeons achieved significantly better scores in all parameters at the medium level, with better centering (P = .001), less corneal injury (P = .02), fewer spikes (P = .03), less time operating without a red reflex (P = .0005), better roundness of the capsulorhexis (P = .003), and less time completing tasks (P = .008).
CONCLUSION
The surgical simulator capsulorhexis module showed significant construct validity (P<.05).
目的
比较医学生、住院医师和经验丰富的白内障外科医生在 EYESi 手术模拟器囊膜切开训练模块上的表现。
地点
美国爱荷华大学眼科系，爱荷华市，爱荷华州。
设计
对比病例系列。
方法
本研究包括爱荷华大学的医学生和住院医师以及经验丰富的白内障外科医生。这两个组都没有使用过模拟器的经验。每个参与者都在囊膜切开模块上完成了 4 次试验。
结果
7 位经验丰富的外科医生在简易和中级难度的囊膜切开模块上的总得分明显高于 16 名医学生和住院医师（P =.004 和 P =.000007）。在中级难度水平上，经验丰富的外科医生在所有参数上的得分都显著更好，包括更好的中心定位（P =.001）、更少的角膜损伤（P =.02）、更少的刺突（P =.03）、更少的没有红色反射的操作时间（P =.0005）、更好的囊膜切开的圆形度（P =.003）和更少的完成任务的时间（P =.008）。
结论
手术模拟器囊膜切开模块显示出显著的结构有效性（P<.05）。
