Abstract:
The aim of this meta-analysis was to determine the e ect of orthokeratology (OK) lens on the axial length of the eye globe of Asian children with myopia of low and moderate degree compared with children treated with glasses. PubMed, Embase, Web of Science, and Cochrane Library were searched to collect relative researches on the treatment of OK lens in myopia children from January 2000 to July 2021. The authors adopted thestandardised mean di erence (SMD) as e ect size, to estimate the pooled changes of axial length in Asian myopic children. Seven articles were identi ed. In Asian children with myopia of low to a moderate degree, compared with glasses treatment, axial length decreased signi cantly in the OK Lens group (SMD = -0.84, 95%CI: -1.10 ~ -0.58), with a p-value less than 0.05. According to the follow-up time, the subgroup analysis demonstrated that, SMD = -0.68 (95%CI: -1.43 ~ 0.08, p>0.05) for six months; SMD = -1.00 (95 %CI: -1.38~-0.62, p<0.05) for 12 months; SMD=-0.71 (95%CI: -1.20~-0.21, p<0.05) for two years. In conclusion, in the early treatment, compared with glasses, children with low and moderate myopia wearing OK lenses were more e ective in reducing axial elongation in Asia.
