Abstract: Objective: To analyze the effect of preoperative light simulation training on patients' intraoperative coordination during Small Incision Lenticule Extraction (SMILE) eye surgery. Methods: From April 2022 to July 2022, a total of 252 patients with refractive error who underwent SMILE eye surgery in the refractive surgery center of a tertiary eye hospital in Tianjin were selected by convenient sampling method, and were divided into the experimental group (125 cases) and the control group (127 cases) based on the date of surgery. The experimental group received preoperative light simulation training, while the control group was given routine health education. The scores of the preoperative and postoperative anxiety Self-Assessment Scale (SAS), General Self-Efficacy Scale (GSES) and postoperative satisfaction questionnaire, and postoperative visual recovery were compared between the two groups. Results: After intervention, the anxiety score of patients in the experimental group was lower than that in the control group, and the difference was statistically significant (P<0.05). The self-efficacy score of the patients in the experimental group increased and was higher than that in the control group with statistically significant difference (P<0.05). The number of central positioning, abnormal movement of eye position and negative pressure loss of patients in the experimental group were less than those in the control group. Patients in the experimental group were observed to show better outcome in terms of the visual changes than the control group one day, one week and one month after operation, respectively, and their satisfaction was better than that in the control group with the difference being statistically significant (all P<0.05). Conclusion: Preoperative light simulation training can reduce patients' anxiety, improve their self-efficacy to boost their intraoperative cooperation, help patients to obtain the expected vision earlier, and make the operation safer and more efficient. At the same time, such training can also increase patients' postoperative satisfaction, and enhance their compliance and trust in doctors, nurses and hospitals.
