Methods: a total of 50 adolescent myopic patients who came to our hospital for myopic consultation and treatment from January 2018 to December 2020 were selected, and they were divided into two groups with 25 cases in each group according to their treatment intention and glasses wearing mode. The myopia patients in the frame group were treated with ordinary frame glasses, and the OK lens group was monitored by AL measurement. The visual acuity, intraocular pressure, AL monitoring and HHK were compared between the two groups before and after treatment. Results: there were no significant changes in visual acuity, intraocular pressure, AL monitoring and HHK between the two groups before treatment (P > 0.05), but there were no significant changes in visual acuity, intraocular pressure, AL monitoring and HHK between the two groups after treatment (P > 0.05). However, the visual acuity, intraocular pressure and HHK of OK mirror group were higher than those before treatment, P < 0.05. AL had no significant change, P > 0.05. Conclusion: AL measuring and monitoring OK lens has better effect on prevention and treatment of myopia than conventional glasses, which is worthy of recommendation for adolescent myopia patients who come to our hospital for consultation and treatment of myopia.展开更多
