Comparative Study on the Effects of Different Optical Correction Methods on Astigmatism in Children and Their Myopia Prevention and Control Effect

Myopia, as an ocular disorder characterized by abnormal axial elongation and increased refractive power, has become a significant global public health challenge. Astigmatism often coexists with myopia, not only impairing visual acuity but also reducing the efficacy of myopia control interventions. Consequently, exploring more effective approaches to synergistically control the progression of both myopia and astigmatism has emerged as a key research focus in the field of optometry. Against this backdrop, this study compared four correction modalities—single-focus glasses, point-diffusion technology (PDT) glasses, high non-micro-lens (HNM) frame glasses, and high-astigmatism lenses (HAL) combined with 0.01% atropine—to analyze their effects on total astigmatism and corneal astigmatism in patients, and systematically evaluated their differences in one-year control outcomes among children with myopia. The findings aim to provide a more comprehensive and targeted reference for clinical practice in controlling astigmatism progression and optimizing comprehensive myopia prevention strategies.
