Purpose: to study and compare the dynamics of the spherical equivalent (SE) of refraction and the anterior-posterior length (AL) of the eye in children who wore spectacle lenses Stellest® with embedded rings of high-spherical microlenses Stellest® during three years of observation (main group) and in children who wore monofocal glasses for two years and switched to wearing spectacle lenses with with embedded rings of high-spherical microlenses during the third year of observation (comparison group). Material and methods. The main group consisted of 30 children aged 8–13 years (mean age 10.50 ± 0.36 years) with acquired progressive myopia of mild and moderate degree (mean 3.15 ± 0.19 D), the comparison group — of 32 children aged 8–13 years (mean age 10.6 ± 0.2 years) with mild and moderate myopia (mean 2.68 ± 0.18 D). After 2 years of observation, 20 children in this group were transferred to spectacle lenses with with embedded rings of high-spherical microlenses. The control group included 30 children aged 10–15 years (mean age 12.60 ± 0.23 years) with myopia, who had been using monofocal glasses for the last year. The dynamics of SE cycloplegic refraction and AL of the eye were assessed. Results. The increase in refractive error in the main group was 0.24 ± 0.07 D over 3 years and 0.04 ± 0.03 D over the third year of observation, in the comparison group — 0.99 ± 0.15 D over 3 years and 0.04 ± 0.05 D over the third year of observation. In the control group, the increase in refractive error was 0.69 ± 0.09 D over the 1 year of observation. The elongation of the AL of the eye was 0.27 mm in the control group versus 0.07 mm in the main group and 0.08 mm in the comparison group. Conclusion. Constant wearing of glasses with embedded rings of highspherical microlenses leads to pronounced inhibition of the progression of myopia in children during three years of observation. After replacing monofocal glasses with glasses with embedded rings of high-spherical microlenses, a significant slowdown in the progression of myopia and eye growth is noted in children with myopia compared to the previous observation period.
