Abstract:
In recent years, the prevalence of myopia has continued to rise, with an expanding affected population, making it a significant public health challenge both in China and globally. Elongation of the axial length in myopic eyes can induce a series of pathological changes in intraocular structure and function, increasing the risk of blinding ocular diseases such as retinal pathologies. Since myopia is difficult to reverse once established, scientific intervention is necessary to control its progression and reduce the likelihood of ocular complications. As a current research focus in myopia control, the clinical application of orthokeratology lenses has attracted considerable attention. This article highlights that orthokeratology lenses, worn overnight, reshape the corneal curvature and create a myopic defocus signal in the peripheral retina. This mechanism effectively inhibits excessive axial elongation and slows myopia progression. Clinical evidence indicates that orthokeratology can reduce axial elongation by 30% to 50%, accompanied by a short-term increase in choroidal thickness. This article also analyzes the advantages and limitations of orthokeratology and explores its potential synergistic effects when combined with other interventions such as low-dose atropine. The aim is to provide key theoretical and practical references for clinical myopia control.
