Objective: To assess the efficacy of video-assisted Wetlab eyelid surgery teaching. Methods: From April 2021 to September 2021, the porcine orbit model was used to conduct a Wetlab teaching course on eyelid surgeries among trainees of standardized training for residents in Zhongshan Ophthalmic Center, Sun Yat-sen University. The control group (12 trainees) used conventional teaching methods. Video-assisted teaching was offered to the test group (15 trainees) based on conventional teaching methods. The videos records of the 3rd, 6th, and 9th practices were scored to analyze the teaching efficiency. Results: Trainees from the 2 groups showed a simila baseline and learning curve. Rapid improvement was found between the 3rd and 6th practice (P3–6=0.001 in control group, P3–6<0.001 in test group). The increment was slower between the 6th and 9th practice (P6–9=0.007 from control group, P6–9=0.012 from test group). Longer time was required by trainees from the control group at the 3rd practice [(80.3±16.1) min]. As they practiced more, the time required gradually decreased and remained stable (P3–6=0.040, P6–9=0.886, P3–9=0.020 from control group). Trainees from the test group spent less time at the 3rd practice [(71.7±15.0) min]. The time remained stable during all practices (P3–6=0.568, P3–9=0.519 from test group). Conclusion: Video-assisted teaching can help trainees get familiar with surgical operations and improve the efficiency of practices.
