We have developed a virtual reality (VR) simulator for phacoemulsification (phaco) surgery. The current work aimed atdeveloping a performance index that characterizes the performance of an individual trainee. We recorded measurementsof 28 response variables during three iterated surgical sessions in 9 subjects naive to cataract surgery and 6 experiencedcataract surgeons, separately for the sculpting phase and the evacuation phase of phacoemulsification surgery. Wefurther defined a specific performance index for a specific measurement variable and a total performance index for aspecific trainee. The distribution function for the total performance index was relatively evenly distributed both for thesculpting and the evacuation phase indicating that parametric statistics can be used for comparison of total averageperformance indices for different groups in the future. The current total performance index for an individual considersall measurement variables included with the same weight. It is possible that a future development of the system willindicate that a better characterization of a trainee can be obtained if the various measurements variables are givenspecific weights. The currently developed total performance index for a trainee is statistically an independentobservation of that particular trainee.
