Objective: To determine knowledge and behavior of contact lens wear in medical students and medical residents in Vajira hospital.
Methods: A cross-sectional study using questionnaire was conducted among medical students and medical residents who wore contact lenses within the recent one year in Vajira hospital.
Results: A total of 660 (480 of medical students and 180 of residents) were recruited in this study. Twenty-four percent in medical student group and 17% in resident group wore contact lens in recent one year. The majority was female in both groups (79.3% and 80.6%, respectively). The average age was 21.4 years in medical student group and 27.8 years in resident group. The main reason for wearing contact lens is visual correction (67.3%). Approximately sixty percent in both groups wore monthly soft contact lens following by daily disposable lens (43.5%). Six improper contact lens compliance and care practices were reported as sleeping with their lens (22.6%), swimming with lens (26.5%), topping off lens storage solution (20.0%), not cleaning lens case daily (57.7%), prolonged wear over replacing schedule (18.4%) and no rubbing and rinsing (33.7%). Seventy-three percent in medical student group and 48.4% in residency group were classified as good behavior. The prevalence of good contact lens behavior in medical students were significantly higher than that of medical resident (p=0.013). However, the majority of participants in both groups were categorized in good knowledge (p=0.297). In all participants, we found statistical significant different between behavior and knowledge (p=0.001)
Conclusion: The majority of participants in both groups have good knowledge. However, medical student group has better behavior in contact lens wear and care compare with medical resident group.
