Official title
Comparative Study of Visual Function Training With Defocus-Enhanced Spectacles vs. Single Vision Spectacles on Myopia Control in Children
Overview
The purpose of this study is to compare the effectiveness of vision function training using defocus-enhanced spectacles (DIMS) versus single vision spectacles combined with vision function training in controlling myopia progression in children aged 6-18 years.
Interventions
- Device Defocus-enhanced spectacles
Vision function training while wearing defocus-enhanced spectacles - Device Single vision spectacles
Vision function training while wearing single vision spectacles
Primary outcome measures
- Change in spherical equivalent 12 months after the commencement of training. [Time frame: Regular sessions commenced from the day of the initial training and continued until 12 months after the first visual training session.]
Secondary outcome measures (1)
- Change in axial length 12 months after the commencement of training. [Time frame: Regular sessions commenced from the day of the initial training and continued until 12 months after the first visual training session.]
