Analysis of Corrective Power and Axial Length in Myopic Children Wearing Single-Vision Spectacles
Abstract
Purpose : This study aimed to longitudinally evaluate changes in corrective power and axial length in myopic children wearing single-vision spectacles, and to compare these changes according to age and gender.
Methods : A total of 27 eyes from myopic children aged 7 to 11 years, who wore single-vision spectacles and had no prior experience with myopia control lenses or other interventions, were included. Differences according to age and gender were compared, and the correlation between corrective power and axial elongation was analyzed. All statistical analyses were conducted using SPSS version 31.0 (SPSS Inc., Chicago, IL, USA).
Results : The average axial length of all subjects (n = 27 eyes) increased significantly by 0.28 mm, from 24.03±1.12 mm at baseline to 24.31 mm after 6 months. In the age group comparison, the 7–8 years group (n=14 eyes) showed an average elongation of 0.37±0.19 mm, while the 9–11 years group (n=13 eyes) showed 0.18 mm. The difference between the two groups was statistically significant (p=0.003). According to gender, males (n=14 eyes) showed an average increase of 0.32±0.21 mm and females (n=13 eyes) showed 0.24±0.14 mm, with no significant difference between the two groups (p=0.218).
Conclusion : In this study of myopic children wearing single-vision spectacles, significant increases in corrective power and axial length were observed over a six-month period, with more rapid elongation found in the 7 to 8 years age group among children aged 9 to 11 years. Further studies with larger populations are needed to clarify age-related axial elongation trends, and the present findings may serve as a foundation for future strategies in myopia management and control.
