What is Objective Assessment of Intraoperative Technical Skill in Capsulorhexis Using Videos of Cataract Surgery about?

## Purpose: Objective assessment of intraoperative technical skill is necessary for technology to improve patient care through surgical training. our objective in this study was to develop and validate deep learning techniques for technical skill assessment using videos of the surgical field. ## Methods: We used a data set of 99 videos of capsulorhexis, a critical step in cataract surgery. one expert surgeon annotated each video for technical skill using a standard structured rating scale, the international council of ophthalmology's ophthalmology surgical competency assessment rubric:phacoemulsification (ico-oscar:phaco). using two capsulorhexis indices in this scale (commencement of flap and follow-through, formation and completion), we specified an expert performance when at least one of the indices was 5 and the other index was at least 4, and novice otherwise. in addition, we used scores for capsulorhexis commencement and capsulorhexis formation as separate ground truths (likert scale of 2 to 5; analyzed as 2/3, 4 and 5). we crowdsourced annotations of instrument tips. we separately modeled instrument trajectories and optical flow using temporal convolutional neural networks t
