To develop an indigenous "Do it yourself" (DIY) three-dimensional (3D) ophthalmic surgery recording system and validate the perception of stereopsis using it.
A cross-sectional survey of practicing ophthalmologists with post-postgraduation experience of at least 5 years for perception of stereopsis for three different surgeries was performed; cataract, retinal detachment, and intravitreal drug injection were recorded on DIY assembly, viewed on VRBOX and using laptop videos and pseudo 3 d videos as control.
The laptop videos and 3D VR Box videos received higher ratings for stereopsis than the pseudo 3D videos. The parameters that received significantly higher ratings on the 3D VR Box viewing were instrument's position relative to the ocular surface in cataract surgery, anterior chamber depth during capsular staining, ophthalmic visco-surgical device injection, capsulorhexis, phaco tunnel depth, movement of nuclear fragments in the anterior chamber, and intra-ocular lens tilt in the capsular bag during cataract surgery ( P < 0.05). In scleral buckling surgery, the parameters that were significantly rated higher on VR Box were globe contour, separation of the scleral plane from muscle, and explant plane ( P < 0.05). Furthermore, the depth of the needle in the vitreous cavity while administering intravitreal drug injection was also rated significantly higher on VR Box ( P < 0.05). However, the ratings for the depth of corneal incision, depth of scleral incision, overall color, and overall quality were not different statistically when compared between laptop and VR Box viewing.
DIY 3D recording assembly offers a superior means of appreciating depth at various stages of cataract surgery, scleral buckling, and intravitreal drug injection when compared to laptop viewing and can serve as an effective tool for skill transfer.
开发一种本土的“自己动手”（DIY）三维（3D）眼科手术记录系统，并验证其立体感知效果。
对具有至少 5 年研究生毕业后经验的执业眼科医生进行了一项横断面调查，以评估他们对三种不同手术的立体感知能力；白内障、视网膜脱离和玻璃体内药物注射分别记录在 DIY 组件上，在 VRBOX 上观看，并使用笔记本电脑视频和伪 3D 视频作为对照。
笔记本电脑视频和 3D VR Box 视频的立体感知效果评分高于伪 3D 视频。在 3D VR Box 观看中，仪器在白内障手术中相对于眼球表面的位置、囊袋染色时的前房深度、眼科粘弹剂注射、囊膜切开、前房核碎片运动以及白内障手术中人工晶状体在囊袋内的倾斜等参数获得了更高的评分（P<0.05）。在巩膜扣带手术中，在 VR Box 上评分显著更高的参数是眼球轮廓、巩膜平面与肌肉分离以及植入物平面（P<0.05）。此外，在玻璃体内药物注射时，VR Box 上观察到的玻璃体腔内针头深度也显著更高（P<0.05）。然而，与笔记本电脑观看相比，角膜切口深度、巩膜切口深度、整体颜色和整体质量的评分在笔记本电脑和 VR Box 观看之间没有统计学差异。
与笔记本电脑观看相比，DIY 3D 记录组件在白内障手术、巩膜扣带和玻璃体内药物注射的各个阶段提供了更好的深度感知方式，并且可以作为一种有效的技能转移工具。
