虚拟现实技术和猪眼模拟训练在白内障住培教学中的对比研究

Comparative study of virtual reality technology and pig eye simulation training in residency training for cataract surgery

目的探索虚拟现实(virtual reality,VR)技术和猪眼模拟训练在眼科白内障住院医师规范化培训(简称住培)教学中的应用,比较两种训练模式的体验感差异。方法选取2021年8月至2021年10月期间在浙江大学医学院附属第一医院眼科专业基地的二年级和三年级住院医师作为研究对象,学员系统接受VR白内障模拟训练和猪眼白内障模拟训练,训练结束后通过调查问卷调查住院医师对两种培训模式的主观感受。结果VR模拟训练成绩为(2.15±0.45)分,猪眼模拟训练成绩为(3.43±0.44)分;在立体感、操作手感、对临床操作帮助度、激发学习兴趣等主观指标上,住院医师对猪眼模拟训练的认可度更高,两种训练方式都不会导致明显的头晕和视觉症状。结论在眼科白内障住培教学中,VR模拟教学一定程度上尚不能完全取代动物眼球模拟教学,但是VR技术也有其优势,两者可以优势互补、相辅相成。

Objective The current study aimed to compare the subjective experience of virtual reality(VR)technology with pig eye simulation training in ophthalmology teaching,and to explore whether VR could really replace the traditional animal eye teaching.Methods The second grade and third grade residents,in the standardized training base for ophthalmology of our hospital from August 2021 to October 2021,were enrolled in the current study.They received VR and pig eye cataract simulation training,respectively.After the training,their subjective assessments about the two training modes were investigated by questionnaire.Results The average score of the VR simulation training questionnaire was(2.15±0.45),and accordingly the animal eye simulation training was(3.43±0.44).In terms of each item,such as stereoperception,handling feeling,contribution to clinical operation,and stimulating interest in learning,animal eye simulation training had higher Approbation Degree,and neither of the two training methods caused obvious dizziness and visual symptoms.Conclusion The results suggest,to some extent,in the teaching of ophthalmic cataract surgery,VR simulate training cannot completely replace animal eye simulation training at present.However,VR technology also has its advantages,and the two could complement each other.
