Early Intervention for Premyopic Children

Condition(s) studied

Investigational drug(s) / intervention(s)

MiyoSmart Spectacles: No power in the central optic zone of DIMS lens for premyopic children with normal vision. Before entering elementary school, eligible preschoolers are asked to wear the DIMS spectacles after kindergarten hours and during weekends and holidays. After entering elementary school, full-time mode wearing of DIMS spectacles is required.

0.01% atropine: daily use of non-preservative 0.01% atropine eye drop for each eye over the study period.

Study summary

The purpose of this research project is to add evidence of pharmacological (0.01% atropine) and optical (Defocus Integrated Multiple Segments spectacle lenses) approaches for myopia prevention among premyopic preschoolers, which may contribute to a better understanding of the intervention strategy for myopia control in premyopic children.
