Abstract:
Objective:To evaluate the efficacy of defocus incorporated multiple segments (DIMS) on spherical equivalent (SE) and axial length (AL) in myopic children.Methods:Clinical studies on the progress of DIMS lens intervention in myopia reported in CNKI, Wanfang Data, VIP, China Biomedical Literature Database, PubMed, Embase, Cochrane Library, and Web of Science from the establishment of the database to June 2023 were searched.The experimental group and control group used DIMS lens and single vision lens (SVL) for intervention, respectively.Two researchers independently conducted the literature search, screening and data extraction based on the inclusion and exclusion criteria.Literature quality and risk of bias were evaluated in accordance with the requirements of the Cochrane Manual.Meta-analysis was performed using Revman 5.4 software.Results:A total of 7 clinical studies using DIMS lenses to intervene in the development of myopia were included .Seven studies provided complete SE data for analysis, with sample sizes of 1 164 eyes and 1 140 eyes for the DIMS group and SVL group, respectively.Five studies provided complete AL data for analysis, with sample sizes of 339 eyes and 315 eyes for the DIMS group and SVL group, respectively.There were statistically significant differences in SE and AL between DIMS group and SVL group (SE: WMD=0.40, 95% CI: 0.32-0.47, P<0.001; AL: WMD=-0.14, 95% CI: -0.17--0.11, P<0.001).DIMS lens could effectively delay SE progression and AL growth in myopic patients. Conclusions:DIMS lenses could delay the increase of SE and AL to a certain extent.
