We have developed a virtual reality (VR) simulator for phacoemulsification surgery. The current work aimed atdeveloping a relative performance index that characterizes the performance of an individual trainee. We recordedmeasurements of 28 response variables during three iterated surgical sessions in 9 experienced cataract surgeons,separately for the sculpting phase and the evacuation phase of phacoemulsification surgery and compared their outcometo that of a reference group of naive trainees. We defined an individual overall performance index, an individual classspecific performance index and an individual variable specific performance index. We found that on an average theexperienced surgeons performed at a lower level than a reference group of naive trainees but that this was particularlyattributed to a few surgeons. When their overall performance index was further analyzed as class specific performanceindex and variable specific performance index it was found that the low level performance was attributed to a behaviorthat is acceptable for an experienced surgeon but not for a naive trainee. It was concluded that relative performanceindices should use a reference group that corresponds to the measured individual since the definition of optimal surgerymay vary among trainee groups depending on their level of experience.
