Virtual reality vitrectomy simulator

In this study, a virtual reality vitrectomy simulator is being developed to assist Ophthalmolgy residents in correcting retinal detachments. To simulate this type of surgery, a three dimensional computer eye model was constructed and coupled with a mass-spring system for elastic deformations. Five surgical instruments are simulated including: a pick, blade, suction cutter, laser, and drainage needle. The simulator will be evaluated by a group of fellows and retinal surgeons with a subjective Cooper-Harper survey commonly used for flight simulators.
