Clinical Evaluation of Multifocal Soft Contact Lenses in Correcting Refractive Amblyopia Myopia in Children

Abstract

Pediatric refractive amblyopia myopia, a common type of abnormal visual development in children, easily leads to imbalance of binocular visual function, increased risk of amblyopia, and accelerated progression of myopia, which has become a key concern in the field of children's eye health. This study selected 68 children with refractive amblyopia myopia from the Optometry Center of Tianjin Eye Hospital from August 2023 to June 2024, divided into an observation group (34 cases, wearing multifocal soft contact lenses) and a control group (34 cases, wearing single-vision frame glasses). Both groups were followed up for 1 year, and relevant indicators were analyzed by independent sample t-test, multiple linear regression, and binary Logistic regression. The results showed that the progression of spherical equivalent in the observation group was (-0.32±0.38) D, which was 64.8% less than that in the control group (-0.91±0.47) D (P<0.001); the axial growth was (0.26±0.17) mm, which was 35.0% less than that in the control group (0.40±0.22) mm (P=0.003). The type of glasses worn was the main factor affecting the changes in spherical equivalent and axial length, and multifocal soft contact lenses could reduce the risks associated with refractive amblyopia myopia (OR=1.85, 95% CI=1.127-3.038, P=0.015). In conclusion, multifocal soft contact lenses can effectively delay the progression of refractive amblyopia myopia in children, reduce axial growth, and are a safe and effective correction method.
