Saleh, FRCSEd, FRCOphth otion analysis has been validated as a tool to evaluate surgical skill. We investi- gated a novel computer vision–based tool for the evaluation of surgical move- ments during cataract surgery. A prospective cohort analysis of 2 groups was per- M formed. Ten videos of junior surgeons (ie, those with 200 cases) and 10 videos of senior surgeons (ie, those with 1000 cases) were analyzed. Movement parameters were mea- sured over an entire procedure. Significant statistical differences were found between novice and expert surgeons for total path length (P=.002), number of movements (P=.05), and total time (P=.004). Our study has shown that computer vision–based motion analysis can be successfully applied to video recordings of cataract surgery to provide robust measurements of instrument mo- tion. Further work needs to be done to evaluate its usefulness in training and feedback. JAMA Ophthalmol. 2013;131(5):659-661.
