Real–world outcomes on myopia management efficacy of diverse segmented defocus optics (DSDO) and defocus incorporated multiple segments (DIMS) spectacle lenses in Chinese children: An initial 12–month prospective clinical study

Both DSDO and DIMS spectacle lenses retarded AL elongation. DSDO showed more stable myopia control effect comparing to DIMS, especially in groups of SER≤-2.0D sub-groups and older patients. DSDO showed initial potential myopia prevention effect in pre-myopic children compared with historical SVS lenses data. However, the small sample and no control group in pre-myopes of this study are key limitations. Further research is needed to confirm and understand DSDO's role for pre-myopic children.
