THE EFFECTIVENESS OF ORTHOKERATOLOGY LENSES IN CONTROLLING MYOPIA IN CHILDREN AND A COMPARATIVE ANALYSIS WITH OTHER CORRECTION METHODS (TWO-YEAR RESULTS)

Abstract

Purpose – to conduct a comparative analysis of the effectiveness of orthokeratological lenses (OKL) and other correction methods in control in school-age children with myopia.

Material and methods

This study compares the effectiveness of OKL, defocus spectacle lenses, and monofocal glasses in controlling myopia in children. A total of 55 schoolchildren with myopia were included in the study and divided into three groups: Group I (OKL users), Group II (defocus spectacle users), and Group III (monofocal spectacle users). Over a period of 24 months, patients underwent regular ophthalmological examinations, and changes in axial length (AL) were monitored.

Results

The results demonstrated that myopia progression was the slowest in Group I (OKL users), with an AL increase of 0.27±0.03 mm. Group II (defocus spectacle users) showed a higher increase (0.49±0.08 mm), while Group III (monofocal spectacle users) exhibited the most significant axial elongation (0.63±0.04 mm).

Conclusion

The use of OCL in the control of myopia has a more stable effect on the increase of AL. Patients using OKL experienced slower eye elongation, thereby limiting myopia advancement. Defocus spectacle lenses also showed reduced progression compared to monofocal glasses. This study supports the use of OKL as a recommended strategy for myopia control. In cases of high myopia and rapidly progressing myopia, a comprehensive and detailed investigation of the use of OKL or defocus- lens spectacles may be considered appropriate.
