CatAR: A Novel Stereoscopic Augmented Reality Cataract Surgery Training System with Dexterous ...
summary
A stereoscopic video see-through AR system is built that lets trainees use real forceps with instrument tips tracked to 20 µm tip accuracy using 2 infrared cameras and 1 reflective marker and displays stereo on dual 4K monitors through microscope eyepieces. Five training modules with 31 parameters are implemented and tested with 28 participants, producing significant improvement in 97% of parameters after one hour and discriminating novice versus experienced users, showing effective short‑term skill transfer and promising validity for cataract training.
