Changes in the anatomical and functional parameters of the eye when using glasses with Stellest™ lenses in children with progressive myopia

Abstract

Relevance. Myopia is one of the most common refractive pathologies in the world. By 2050, according to WHO 2015, more than half of the world’s population will suffer from myopia, which will lead to the risk of developing pathologies associated with the progression of myopia, such as glaucoma, macular degeneration and retinal detachment. The use of various modern methods to control myopia can slow down the progression of myopia, which potentially reduces the risks of complications. Objective: to evaluate changes in the anatomical and functional parameters of the eye (clinical refraction, axial length, accommodation functions) in children with progressive myopia corrected with glasses with Stellest lenses in different age groups. Materials and methods. The study was conducted on the basis of the Eye Microsurgery Clinic of the Stavrapol State Medical University. Glasses with Stellest lenses were assigned to 80 children aged 8 to 16 years. The average age of the children was 11 ± 0.12 years. The children were divided into three age groups: 1st – primary school; 2nd -middle school; Group 3 – senior school. After the examination, the children were selected glasses with Stellest lenses. The average period of wearing glasses with Stellest lenses was 12 months. Clinical refraction, axial length and accommodation functions were evaluated during the observation. Results. The change in refraction depended on the age of the child. The greatest increase in refraction by 0.40 ± 0.02 D was observed in the younger age group, and the smallest (0.27 ± 0.02 D) in children of secondary school age. In the group of children of senior school age, the increase in refraction was +0.32 ± 0.03 D. The axial length of the eye in children of the primary school group after 12 months of wearing glasses with Stellest lenses signifi cantly increased by an average of 0.28 ± 0.03 mm. This axial growth of the eye correlates with an increase in myopic refraction in the same group of children. In the group of children of senior school age, the growth of PZO was 0.1 ± 0.04 mm. There was an increase in the accommodation reserve, the positive relative accommodation and the relative accommodation in all groups. Conclusions. The study showed that wearing glasses with Stellest lenses helps to reduce the rate of progression of myopia and increase the accommodative functions of the eye, which improves the adaptive capabilities and performance of the visual analyzer in all age groups of schoolchildren
