The experience of using orthokeratology lenses in the regional ophthalmological dispensary for 2021–2023

Aim: To evaluate the structure of refractive errors in patients using orthokeratology lenses in dynamics over the past three years, to present clinical observations. Methhods. Over the past three years (2021–2023), we have observed 640 patients using orthokeratology lenses to correct refractive errors. Results. There was a positive trend in the increase in the selection of orthokeratology lenses from 296 (23.9 %) in 2021 to 521 (42.1 %) in 2023. In the structure of refractive errors, myopia occupies the leading position – 629 (50.8 %) lenses, astigmatism with 569 (45.9 %) lenses is on second place. A positive trend was revealed in hyperopia up to 4 diopters from 6 (14.6 %) in 2021 to 23 (56 %) in 2023. Conclusions. The number of orthokeratology lens selections is growing, and clinical examples prove the effectiveness and comfort of using this correction.
