Abstract

Purpose: To evaluate a human cadaveric model in improving knowledge and comfort of ophthalmology residents performing a lateral canthotomy/cantholysis. Methods: A prospective study was conducted in ophthalmology residents, who participated in a workshop including an interactive lecture followed by hands-on training on a human cadaver. The lecture consisted of the indications and techniques of lateral canthotomy/cantholysis, along with video-demonstration of proper technique. Residents practiced the procedure on cadavers under faculty supervision. Knowledge and comfort level of conducting the procedure was assessed pre- and post-workshop. Results: Post-workshop, the residents showed a significant improvement in general knowledge regarding the technique of the procedure. Pre-workshop, the average knowledge score was 9 points out of 18 and this improved post-workshop to 12 points out of 18 (p < 0.0001). Residents showed a significant improvement in comfort levels performing the procedure. Using a Likert scale, the average comfort level of performing the procedure rose from 2.5 (Fair) prior to the workshop to 4 (Very Good) post-workshop (p = <0.01). All participants reported an average score of 4.91 (1 = Strongly Disagree, 5 = Strongly Agree) that the human model workshop was clinically applicable to their training and would impact the quality and safety of patient care. Conclusion: The study demonstrated an increase in knowledge and comfort in performing lateral canthotomy and cantholysis using a cadaver model. With the time-sensitive nature of orbital compartment syndrome, it is imperative that physicians are comfortable in performing this procedure to prevent permanent vision loss.
