To evaluate the residents’ performance on the cataract simulator and residents’ feedback on the usefulness of the simulator in improving their confidence in the phacoemulsification surgeries.
Ten junior Ophthalmology residents from Singapore National Eye Centre participated in this study and they underwent a 2-hour instructional course prior to the commencement of the cataract simulator training using Eyesi Cataract Simulator (VRmagic, GmbH, Mannheim, Germany). Upon completion of the learning modules, the number of the individual’s attempts, scores and time taken were recorded. In addition, the residents were also asked to fill out a satisfaction questionnaire using 5-point Likert scale regarding the effectiveness of the simulator to improve their confidence in phacoemulsification surgeries.
Of the participants, 70% were year 1 residents, 30% were male with the mean age of 28.9 ± 1.7. Of the basic microsurgical skills, the residents found that the navigation skills, intracapsular navigation and the forceps training were the most useful modules. About half of the resident (50%) did not find the anti-tremor training improved their confidence in their cataract surgeries. Most of the residents (90%, n=9) agreed that the EyeSi simulator helps to improve instrument handling under microscope, hand/eye coordination and handling of the foot pedals. Regarding the performance, the overall mean score, time taken and number of attempts per module were 61.2 ± 35.7, 86.3 s ± 83.8 and 4.9, respectively. The year 2 residents had better mean task score than the year 1 residents (67.8 vs 58.7, p < 0.001) using a shorter time (66.2 seconds vs 75.5 seconds, p=0.002). There was no significant difference in the number of attempts between the year 1 and 2 residents. Overall, 90% of the residents agreed that the use of cataract simulator has improved their confidence in performing phacoemulsification in the operating room.
The use of cataract simulator has been shown to increase the self-reported confidence level of the junior Ophthalmology residents in performing their cataract surgeries. A further study will be of great value to evaluate the impact of the cataract simulator training on the performance of the residents’ cataract surgeries such as the intraoperative time, postoperative visual outcome and complication rate.
