Effect of MiYOSMART iQ Spectacle Lenses on Myopia Progression in Children

This prospective, single-center study aims to evaluate the efficacy and safety of MiYOSMART iQ spectacle lenses with DIMS (Defocus Incorporated Multiple Segments) and Triple Enhanced Design (TED) technology in slowing myopia progression in children aged 8-11 years. 35 children with myopia (spherical equivalent -0.5 to -6.0 D) will be prescribed MiYOSMART iQ lenses and followed for 6 months. The study will compare changes in spherical equivalent refraction and axial length against a historical control group (n=35) using ANCOVA. Secondary outcomes include measurements of peripheral refraction and contrast sensitivity at the first prescription. The study hypothesis is that wearing MiYOSMART iQ lenses for 6 months significantly slows myopia progression compared to single-vision spectacle correction.
