Virtual Mentor Cataract Surgery Trainer
Abstract
The Virtual Mentor Cataract Surgery Trainer is a computer based, cognitive simulation of phacoemulsification cataract surgery. It is designed to teach the steps of the surgery, common errors, and ways to rectify these errors. This award supports the development of two modules (capsulorhexis and nucleus removal) and their integration with the existing hydrodissection module. We interviewed phaco experts, and edited video of the interviews in to brief clips for use as just in time feedback to learners, and as answers to Help and Reference questions. Our database now includes over 100 edited expert video clips. Combining information from expert interviews with our own observations, we created the overall architecture for the simulation, including action options, questions, and appropriate expert stories for each step of the procedure. We wrote pathways and scenarios for the capsulorhexis and nucleus removal modules. We wrote questions and answers for Help and Reference sections for these modules. We created 3D animations for steps and complications of capsulorhexis module. The value of this teaching method has been validated in a study that has recently been accepted in a peer reviewed journal. We have made significant progress in expanding the prototype to include new modules.
