Effectiveness of an online educational video intervention to improve the knowledge and behavior of contact lens care during the COVID-19 pandemic: A pre-test/post-test design.

Objective: To assess the effectiveness of an online educational video in improving contact lens (CL) care knowledge and behavior.

Methods: Participants completed a 47-item questionnaire on their CL hygiene knowledge and wear and care behavior. A 5-min CL educational video was shown, and participants completed a post-test. After 2 months, the same questionnaire was used to determine knowledge retention and behavioral changes. Descriptive statistics and McNemar's tests were performed.

Results: The mean age of the 132 enrolled participants was 24 years, and 61% were female. The knowledge scores significantly improved after watching the educational video (p < 0.001). Two months after the intervention, the participants reported changes in their hygienic behavior (p < 0.001).

Conclusions: Online video-based learning is an effective educational tool for improving the knowledge and behavior of CL care.

Practice Implications: Patient education via online videos is an innovative and successful strategy that raises awareness, increases patient knowledge, and encourages preventative health behavior to avoid CL-related complications.
