Evaluation of the impact of short term manual small incision cataract surgery (MSICS) training program on trainees with varying prior surgical experience using international council of ophthalmology-ophthalmology surgical competency assessment rubrics (ICO-OSCAR).

PURPOSE: To assess the learning curve of MSICS in three different groups of trainees with varying prior MSICS experience. To evaluate the effectiveness of ICO OSCAR for objective assessment of surgical skill transfer. METHODS: Ninety-five MSICS trainees were divided into three groups as 1st year resident, fellow and external trainee. Each group were evaluated for their surgical skill acquisition during one month MSICS training program using ICO-OSCAR. Each trainee performed an average of 19 surgeries. The progress in the learning curve of the three groups of trainees was analyzed by evaluating the mean scores in sets of five consecutive cases. Complications during the training period were also noted. RESULTS: The study evaluated a total of 1842 cases. The fellows and external trainees, with prior MSICS experience, had an initial mean score of 57.57 ± 16.16 and 56.86 ± 17.82 respectively, whereas the 1st year resident group had a relatively low initial mean score of 45.91(p = 0.009). The difference in mean scores between the 1st year resident group and other groups significantly reduced towards the end of training. The most common complications made by 1st year residents were in sclero-corneal tunnel construction. The external trainee group had statistically significant higher rates of zonular dialysis in the study. CONCLUSIONS: ICO-OSCAR is an effective tool for assessing MSICS training program. Structured short term MSICS surgical training program is effective in surgical skill transfer, especially in novice surgeons.

An objective evaluation of simulated surgical outcomes among surgical trainees using manual small-incision cataract surgery virtual reality simulator.

Purpose: The purpose of this study was to evaluate trainee performance across six modules of a virtual reality (VR) simulator. Methods: A retrospective observational study was conducted on 10 manual small-incision cataract surgery (MSICS) trainees who practiced cataract surgery on an MSICS VR simulator for one month. They were assessed in six major steps which included scleral groove, tunnel dissection, keratome entry, capsulorhexis, nucleus delivery, and intraocular lens (IOL) insertion under a trainer's supervision. The information included in their score metrics was collected, and their overall performance was evaluated. Results: Thirty attempts were evaluated for scleral groove, tunnel dissection, and capsulorhexis and 15 attempts for keratome entry. Candidates had varied results in the dimensional aspects and their rates of complications with a mean satisfactory score of 3.1 ± 4.17, 6.8 ± 5.75, 5.8 ± 7.74, and 1.8 ± 2.57, respectively. Nucleus delivery (n = 5) had more of iris pull and IOL insertion (n = 5) had more of lost IOL as complications but both had a higher satisfactory outcome. Conclusion: A VR simulator is a useful tool for training surgeons before their entry into live surgery. It is an effective method for evaluating objectively the structural characteristics of each phase in MSICS and their associated complications, helping them anticipate it earlier during live surgery by giving them a near real world experience.
