Abstract

Surgical videos were recorded using DIY 3D recording assembly made by mounting two cameras of either side of beam splitter and video outputs fused live in side to side format using wedding video mixer.standard 2D video and pseudo stereo video made by duplicating 2D video to side by side format served as control1,2.3Videos:cataract surgery, scleral buckling and intravitreal injection were shown to 20 subjects and evaluated for stereopsis,color,resolution,overall quality and asked for stereopsis of steps relevant to skill transfer:depth of AC,Phaco trench, IOL position,depth of corneal incision in cataract,crescent depth in buckling and needle depth in intravitreal injection.Stereo and psudostereo images were viewed onVRBOX and 2D on 13 inch laptop. Statistically significant higher proportion of subjects rated stereo videos better than control for depth perception of most surgical steps except keratome depth incision. The resolution was rated to be slightly better in standard 2D videos
