Objective: To analyze the advantages and disadvantages of real-time face-to-face online teaching (taking “Tencent Conference” teaching as an example) in medical education and its correlation with ocular surface diseases during
the COVID-19 pandemic, and to provide basis for improving online education programs and preventing dry eye. Methods: The undergraduate students of Xiangya School of Medicine of Central South University were selected
as the research objects. The method of cross-sectional study was used to collect data using questionnaires to study
the effect of real-time face-to-face online teaching and its impact on ocular surface diseases. Results: A total of 131
valid data were collected. Among them, the vast majority of students (84.73%) think real time face to face online
teaching is effective, and 96.18% of the students believe that real-time face-to-face online teaching at least partly
achieved the purpose of learning. However, the interaction between teachers and students and the classroom
atmosphere of real-time face-to-face online teaching needs to be strengthened. In addition, network equipment
is also a problem that real-time face-to-face online teaching needs to face. Meanwhile, the survey showed that
the prevalence rate of dry eye among the students who participated in real-time face-to-face online teaching
reached 66.41%, and there was no correlation between the incidence rate of dry eye and the location of family,
the per capita monthly income of family, the equipment, and whether they paid full attention to the lectures. Conclusion: Real-time face-to-face online teaching is effective in medical education during COVID-19, but
the main problems are insufficient teacher-student interaction, inactive classroom atmosphere and unstable
Internet connection. In addition, real-time face-to face online teaching will increase the incidence of dry eye, so
it is necessary to improve the awareness of eye protection and actively prevent it.
