Early-Onset Myopia Intervention Project
- Conditions
- MyopiaPre-myopia
- Interventions
- Device: Spectacle lenses with highly aspherical lenslets
- Registration Number
- NCT07176949
- Brief Summary
The prevalence of myopia among children has been increasing year by year, which has become a globle public health issue. Studies have shown that defocusing lenses and atroping eyedrops can control the progression of myopia, but there is little evidence of its efficacy in myopia intervention of young pre-schoolers who will face a greater risk of progression to high myopia later in life. Therefore, this study aims to evaluate the effectiveness and safety of spectacle lenses with highly aspherical lenslets (Essilor's Stellest) , as well as 0.01% and 0.05% low concentration atropine eyedrops in myopia intervention among young children aged 3-6.

- Primary Outcome Measures
Name Time Method Changes in cycloplegic spherical equivalence 2 year Measured by an auto-refractometer
- Secondary Outcome Measures
Name Time Method Changes in axial length 2 years Measured by an IOL-Master
Proportion of subjects with non-rapid myopia progression 2 years Rapid myopia progression is defined as: spherical equivalence increase (become less positive or more negative refractive error) of any eye ≥ 0.5 D in half a year.
The duration of non-rapid myopia progression 2 years Rapid myopia progression is defined as: spherical equivalence increase (become less positive or more negative refractive error) of any eye ≥ 0.5 D in half a year.
