Project on Myopia Surveillance and Intervention Services for Preschool Children in Shanghai
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.
