ObjectiveTo systematically evaluate the efficacy of defocus incorporated multiple segments (DIMS) spectacle lenses and Orthokeratology (Ortho-K) in controlling myopia. MethodsThe PubMed, Embase, Cochrane Library, Web of Science, CBM, WanFang Data and CNKI databases were electronically searched to collect clinical studies related to the objects from January 2000 to June 2024. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed by using RevMan 5.3 software. ResultsA total of 8 RCTs and 7 cohort studies were included. The results of meta-analysis showed that both Ortho-K lens and DIMS had better axial control effects than the single vision control group (MD=−0.18, 95%CI −0.21 to −0.15, P<0.01; MD=−0.21, 95%CI −0.27 to −0.15, P<0.01). The Ortho-K had a smaller one-year growth in axial length compared to the DIMS (MD=−0.06, 95%CI −0.08 to −0.04, P<0.01). ConclusionCurrent evidence suggests that Ortho-K and DIMS have better myopia control effects than single lens lenses, while Ortho-K has better myopia control effects than DIMS, but the advantages are not significant. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
