Evaluation of the Effectiveness of Orthokeratological Lenses in Patients with Myopia
Abstract
Myopia (Nearsightedness) is one of the most common refractive errors, particularly among children and adolescents.
Objective. To investigate the effectiveness of orthokeratology lenses in patients with myopia and their impact on the precorneal tear film.
Material and methods. The study on the effectiveness of orthokeratology lenses was conducted on 32 patients with mild to moderate myopia.
Results and discussions. An evaluation of visual acuity after the first night of wearing orthokeratology lenses (OK-lenses) showed an average score of 0.65±0.2. After onemonth, visual acuity increased to 0.96±0.095, and after six months, it slightly decreased to 0.925±0.088. The reserve of relative accommodation (RRA) before correction was 2.6±1.4 diopters; after one month of wearing OK-lenses, the average RRA was 3.82±1.22 diopters, and after six months, it rose to 6.42±0.23 diopters. In the early stages, a reduction in Schirmer's and Norn's test values was observed. However, after six months, the indicators for all parameters increased, which may be attributed to adaptive changes on the corneal surface in response to wearing orthokeratology lenses.
Conclusions.The use of orthokeratology lenses (OK-lenses) demonstrates high effectiveness in correcting myopia and slowing its progression, particularly in children and adolescents.
