It can generate scores for performance in multiple modules based upon errors made, path length, time taken for different simulator tasks, and other variables.
The Eyesi simulator has been used to train residents in cataract surgery at many ophthalmology programs including the Harvard Medical School ophthalmology residency. Many ophthalmology surgical programs have residents perform most of their surgery in their final year. In these unfortunate situations, it is not unusual to discover these surgical deficiencies late in residency. Although most residents can be adequately trained surgically, the occasional resident may have difficulty achieving surgical competencies within the timeframe of a residency program.
5 It is difficult to predict the potential for the acquisition of surgical skills in a novice surgeon. Surgical simulators have been widely used for training in neurosurgery, gastroentrology, laparoscopic surgery, orthopedics, and ophthalmology.1, 2, 3, 4, 5, 6 There is increasing evidence that surgical simulator training improves residents׳ surgical performance in the operating room (OR) and improves surgical outcomes. We also compared variables in a small group of residents who needed extra help in learning cataract surgery to the other residents in the study. Spearman correlation coefficients were calculated between each of the simulator performance and subsequent surgical performance variables. Subsequent surgical performance was assessed using the total number of phacoemulsification cataract surgery cases for each resident, as well as the number performed as surgeon during residency and scores on global rating assessment of skills in intraocular surgery (GRASIS) scales during the third year of residency. Variables collected from the eye surgery simulator included scores on the following modules of the simulator (Eyesi, VRmagic, Mannheim, Germany): antitremor training level 1, bimanual training level 1, capsulorhexis level 1 (configured), forceps training level 1, and navigation training level 1. In a retrospective study, we compared performance of 30 first-year ophthalmology residents on an eye surgery simulator to their surgical skills as third-year residents.
