To improve the state-of-the-art teaching system by creating surgical videos with synchronised vertical 2-split screens.
An ultra-compact, wide-angle point-of-view camcorder (HX-A1, Panasonic) was mounted on the surgical microscope focusing mostly on the surgeons' hand movements. In combination with the regular surgical videos obtained from the CCD camera in the surgical microscope, synchronised vertical 2-split-screen surgical videos were generated with the video-editing software.
Using synchronised vertical 2-split-screen videos, residents of the ophthalmology department could watch and learn how assistant surgeons controlled the eyeball, while the main surgeons performed scleral buckling surgery. In vitrectomy, the synchronised vertical 2-split-screen videos showed the surgeons' hands holding the instruments and moving roughly and boldly, in contrast to the very delicate movements of the vitrectomy instruments inside the eye.
Synchronised vertical 2-split-screen surgical videos are beneficial for the education of young surgical trainees when learning surgical skills including the surgeons' hand movements.
通过创建带有同步垂直双分屏的手术视频来改进现有教学系统。
将一台超紧凑型广角视角摄像机（松下HX - A1）安装在手术显微镜上，主要聚焦于外科医生的手部动作。结合从手术显微镜中的CCD摄像机获取的常规手术视频，使用视频编辑软件生成同步垂直双分屏手术视频。
使用同步垂直双分屏视频，眼科住院医师在主刀医生进行巩膜扣带手术时，能够观看并学习助理医生如何控制眼球。在玻璃体切除术中，同步垂直双分屏视频显示外科医生手持器械的手部动作大致且大胆，这与眼内玻璃体切除器械非常精细的动作形成对比。
同步垂直双分屏手术视频在年轻外科实习生学习包括外科医生手部动作在内的手术技能时，对教学有益。
