Evaluation of the influence of Stellest spectacle lenses on the dynamics of individual indicators of myopia progression in children of different age groups

The problem of myopia growth in children is currently a topical issue among ophthalmologists around the world, since complications caused by myopia can gradually lead to a persistent decrease in visual functions. The purpose. To assess the effect of Stellest spectacle lenses on the dynamics of individual indicators of myopia progression in children of different age groups. Materials and methods. The study was conducted at the clinical sites of the Federal State Budgetary Educational Institution of Higher Education “Astrakhan State Medical University” of the Ministry of Health of the Russian Federation and the Turkmen State Medical University named after M. Garryev in the period from January to December 2024. The study group included 100 children (200 eyes) of the main group – 53 boys (53 %) and 47 girls (47 %), who were prescribed Stellest spectacle lenses and 45 children (90 eyes) of the control group – 25 girls (55.6 %) and 20 boys (44.4 %), who were prescribed monofocal glasses. All patients were aged 4 to 12 years with acquired moderate myopia without concomitant pathology of the visual organ. Patients of the main and control groups were divided into 3 groups depending on age. The examination list included such studies as manifest and cycloplegic refractometry,
visometry without correction and with full correction, biomicroscopy, ophthalmoscopy, determination of the anteriorposterior axis of the eye on an optical biometer (Topcon Aladdin), the nature of vision using a four-point color test, the volume of absolute accommodation, determination of the reserves of relative accommodation in children. The dynamics of the refraction of the anterior-posterior axis of the eye and the data on the reserves of relative accommodation in children of the main and control groups were assessed after 6 months and after a year in comparison with the indicators at the beginning of the observation. Results. Based on the obtained results of the study, we observe that after a year, most children who used Stellest transfocal glasses compared to children who used monofocal glasses have a more pronounced stabilization of refraction during the year, the data of the anterior-posterior axis of the eye changed within the permissible values, a natural tendency to increase the reserves of relative accommodation in both groups was noted, more pronounced in the group of wearing Stellest glasses, which indicates the positive properties of transfocal spectacle lenses on the dynamics of individual indicators of myopia progression in children of different age groups. It is noted that in the group of children aged 8 to 12 years of the main and control groups, the highest percentage of myopia growth is observed, which once again shows the relevance and significance of a more extensive study in the field of transfocal spectacle correction and other methods of monitoring the progression of myopia in children. Conclusion. Early initiation of wearing Stellest spectacle lenses is justified, well tolerated by children aged 4–6 years, allows monitoring the progression of myopia and minimizing potential risks of pathological changes in the eyeball associated with myopia.
