Ocular biological characteristics of children with myopia and rapid axial length changes treated with spectacles with highly aspherical lenslets

In the eyes with HAL treatment, decreased ACD and VCD, thickened CLT, flattened FK, and steepened SK are observed during AL reduction. Lower baseline astigmatism is associated with AL reduction. The AL reduction may suggest the potential efficacy of HAL intervention in myopia control, while providing evidence for optimizing personalized myopia management strategies. Further longitudinal studies are warranted to validate whether rapid AL changes predict sustained treatment efficacy.
