Title : Evaluation and implementation of a probing model for nasolacrimal duct probing simulation: A pilot study in ophthalmology residents
Abstract:
Introduction: Congenital nasolacrimal duct obstruction (CNLDO) is a leading cause of epiphora in children, commonly treated through probing. Traditional training methods, which involve hands-on practice with pediatric patients, face limitations due to ethical concerns and limited patient availability. Simulation-based mastery learning, combined with deliberate practice, offers a solution by providing a structured and repeatable training environment.
Objective: To evaluates the effectiveness of a simulation-based probing model in training ophthalmology residents for nasolacrimal duct probing procedures. The aim is to enhance residents' skills, increase their confidence, and reduce the procedure's duration.
Methods: A study was conducted at Department of Ophthalmology, Prince of Songkla University with 15 ophthalmology residents. The residents participated in a structured training program based on simulation-based mastery learning principles. The program included a video tutorial followed by repeated self-generated practice sessions using a nasolacrimal probing model. Deliberate practice was emphasized, with trainees receiving immediate feedback. Performance was assessed using a validated rubric score, and confidence was self-reported on a 0-4 scale. Pre- and post-practice performance and procedural times were analyzed.
Results: Fifteen residents (8 males, 7 females) participated in the study. Significant improvements in procedural skills were observed following simulation-based mastery learning and deliberate practice. Pre-practice rubric scores increased from 24.20 ± 3.30 to 35.13 ± 4.85, while procedure time decreased from 3.57 ± 1.46 to 1.55 ± 0.45 minutes (p < 0.001). Confidence levels improved from moderate to high with repeated deliberate practice sessions. Residents reported high satisfaction with the structured approach.
Conclusion: This studyA demonstrates the probing model simulation method enhanced ophthalmology residents' procedural skills and confidence in nasolacrimal duct probing. This method provides a cost-effective, ethical alternative to traditional training, ensuring skill mastery through repeated practice and feedback. Future research should examine long-term skill retention and its impact on clinical performance.
