Abstract: Objective: To investigate the effects of an animation video-guided interactive educational device on the educational guidance of school-aged children wearing orthokeratology lenses. Methods: Through the design and development of an animated video-guided interactive teaching tool, educational guidance resources suitable for school-aged children wearing orthokeratology lenses were developed. Using the convenient sampling method, school-aged children who received their first orthokeratology lenses at the optometry center of a tertiary grade A hospital in Beijing from August to November 2024 were selected as the control group, while those who received their lenses from December 2024 to February 2025 were selected as the intervention group. The intervention group received educational guidance using this teaching tool, while the control group received routine guidance. Differences in knowledge mastery and standardization of self-care practice between the two groups were compared, and the intervention effect was evaluated. Additionally, user-friendliness of the tool was assessed in the intervention group, combining quantitative scores and qualitative interviews to understand the children's experience with using the tool. Results: After the intervention, the total score of orthokeratology lenses knowledge [13.00(12.00, 14.00) points], and total score of orthokeratology lenses self-care operation [92.00(90.00, 96.00) points] in the intervention group were significantly higher than those in the control group [11.00(10.00, 11.50) points and 86.00(82.00, 90.00) points, respectively] (all P<0.05). Additionally, participants in the intervention group rated the overall ease of use of the interactive educational device guided by animated videos with a full score rate of 92.47%. Conclusion: The animated video-guided interactive teaching tool can effectively stimulate school-aged children's interest in learning, enhance learning experience and engagement, and help improve their mastery of orthokeratology-related knowledge and self-care skills.
