Abstract

Purpose We performed a prospective study to determine the efficacy of a novel silicone eyelid model in helping train residents to repair marginal eyelid lacerations. Methods 3D design software was used to create a scaffold for a silicone eyelid mold. A total of 18 ophthalmology residents participated in a training session on marginal eyelid laceration repair, practicing on these models. Prior to and following the session, residents anonymously responded to a survey assessing their degree of confidence in repairing marginal and non-marginal eyelid lacerations, as well as their overall opinion of the workshop. Questions related to their confidence and ability utilized a five-point Likert Scale, with higher numbers representing more positive responses. The responses were compared using the Wilcoxon Rank-Sum test. Results Following the training session, the residents showed a significant improvement in confidence and knowledge in the repair of marginal eyelid lacerations. Amongst all residents, the median confidence level for repairing marginal eyelid lacerations increased from 2.00 to 3.00 (p=0.042). The residents with no prior marginal eyelid repair experience reported a larger increase in the degree of confidence with median scores rising from 1.00 pre-session to 2.00 post-session (p=0.01). Residents found the simulation to be beneficial with a median score of 5.00 (IQR 4.00-5.00). When compared to other eyelid simulation models for training, the silicone model was found to be superior with a score of 4.50 (IQR 4.00-5.00). Conclusions 3D printed silicone eyelid models provide an effective and realistic simulation of marginal eyelid laceration repair.
