Objective: to evaluate the effectiveness of orthokeratological correction in the treatment of progressive myopia in children. Material and methods. A retrospective study correction of myopia orthokeratology lenses of 100 patients (178 eyes) with an established diagnosis of myopia of an average degree, undergoing treatment at the Clinic of eye diseases of SSMU. Group I consisted of 50 patients who received OK-correction lenses "Emerald" by Euclid Systems Corporation (USA). The wear time is 2 years. Group II included 50 people (87 eyes), using spectacle correction during the same time. Patients underwent visual acuity testing, biomicroscopy, refractometry, determination of reserves of accommodation, ultrasonic biometry (IOL-Master, CarlZeiss) is a measurement of the size of the front-sadayoshi eyeball, survey after 2 years of using the selected correction. Results. Comparative analysis showed that the use of OK lenses for patients with myopia of an average degree resulted in a significant reduction in the rate of progression of myopia. In the background wearing OK lenses for 2 years has been the increase PZO, PZO dynamics were 0.09±0.05 mm. For the correction of progressive myopia spectacle lens changes were more significant, the dynamics of early school leaving amounted to 0,36±0,11 mm. Conclusion. The identified inhibitory effect of OK-lenses on myopia progression, confirmed by the indices of refraction and ultrasound biometry within 2 years of the study. The data allow us to recommend OK-therapy, as an effective tool for progressive myopia.
