A comparative analysis of orthokerathology correction efficiency in children with progressive myopia

Purpose. To analyze stabilization of myopia when using orthokeratological lenses in children of different age groups. Methods. We have conducted a retrospective analysis of medical records of 146 school age children aged 6 to 16 years with progressive mild and moderate myopia. Follow-up period was 3 years (2020–2022). Results. A significant proportion of myopia progression was identified in children using monofocal glasses, ranging from 59 to 90 % depending on age according to biometry data. According to refractometry data, progression of more than 1 diopter per year was noted in 70–71.8 % of children without OKL. On the other hand, there is a smaller proportion of myopia progression in children with OKL – from 22 to 50 %. Conclusions. The results of the study prove the effectiveness of OKL in different age groups, which allows to recommend OK correction as an effective treatment of myopia progression in children
