Clinical Trial Summary

Objective: To study the effectiveness and safety of low-intensity single wavelength red light in controlling high myopia in children and adolescents.

Clinical Trial Description

Design: The trial was a randomized, controlled, multicenter clinical trial. A total of 190 children aged 3-16 years with high myopia were selected and divided into 95 cases in the test group and 95 cases in the control group. The test group was treated with the Eyesing Instrument developed by Suzhou Industrial Park Zoguan Medical Equipment Co. and conventional optometry. The safety and efficacy of the low-energy laser device in the test group were evaluated by comparing the changes in myopia between the two groups during the observation period. Subjects were screened after signing the informed consent form (performed as early as 7 days before the randomization), and the examination used for screening could use the results of eye examinations performed within 1 week at our hospital, and they were enrolled after confirming that they met the inclusion criteria. On the same day, the grouping was done by randomization, and the glasses were prescribed or the glasses were prescribed in combination with the device according to the grouping results. Visits were performed at 30± 14 days, 90± 14 days, 180± 14 days, 270± 14 days, and 365± 14 days ;
