| Purpose | Lateral canthotomy and cantholysis (LCC) is a time-critical sight-saving emergency procedure but is infrequently encountered and training remains inconsistent. We evaluated the impact of a video-based educational intervention. |
| Methods | A single-centre prospective study was conducted among Ophthalmology, Emergency Medicine, ENT and Foundation clinicians across multiple training grades, improving generalisability. Participants completed pre- and post-intervention questionnaires assessing knowledge and confidence (5-point Likert scale) before and after viewing an 8-minute instructional video. Data on prior procedural exposure, perceived baseline training adequacy, intervention usability, and requirement of any further learning resources were also collected. |
| Results | Forty-eight participants completed both questionnaires. Perceived baseline training adequacy was low (mean 3.02 ± 1.19), with 66.7% rating ≤3. Significant improvements were seen post intervention in theoretical knowledge (3.77 ± 1.13 to 4.56 ± 0.71), equipment identification (3.69 ± 1.26 to 4.67 ± 0.66), and confidence performing LCC (3.38 ± 1.27 to 4.29 ± 0.97) (paired t-test, p < 0.001 in each domain), corresponding to mean increases of 0.79, 0.98, and 0.91 respectively on a 5-point Likert scale. The educational video was highly rated, with most participants rating it ≥4 and 93.8% indicating they would recommend it as a learning resource. Simulation with models and hands-on training (including cadaveric and real-world experience) were the most requested additional resources. |
| Conclusion | A clear and clinically important training gap exists in LCC. A short, scalable video intervention significantly improved self-reported knowledge and procedural confidence, highlighting its value as an accessible training tool in time-critical ophthalmic emergencies. Further evaluation with integrated hands-on simulation training will be essential to determine whether these gains translate into real-world procedural competence and improved patient outcomes. |
