Orthokeratology in slowing the progression of myopia (preliminary studies)

   Orthokeratology is a method of correcting refractive errors, based on the night wearing of special gas-permeable reverse geometry contact lenses that temporarily change the shape of the cornea. The influence of OK-therapy on the progression of myopia deserves a detailed study. Within 3-4 weeks, diagnostics and selection of orthokeratological lenses were carried out in 18 children (36 eyes) aged 8 to 14 years with progressive myopia. There were 7 girls (38.9 %), boys - 11 (61.1 %). The control group consisted of 22 children with myopia aged 8 to 14 years who underwent contact and spectacle correction. As a result of a comprehensive ophthalmological examination, it was found that the use of refractive therapy leads to a decrease in the spherical and cylindrical component of the refractive error when used for 3-4 weeks. In the future, it is planned to continue monitoring in a longer period (1 and 2 years) from the start of refractive therapy. The obtained results of the work carried out allow us to recommend the use of OK lenses in the practice of ophthalmologists for the optical correction of mild and moderate myopia in children and adolescents.
