Abstract

Purpose: To estimate the efficacy of orthokeratology contact lenses in slowing myopia progression.

Methods: Prospective data from 101 to 88 children, aged 6 to 12 years and with myopia between -0.50 and -5.00 D, who completed 2 years of orthokeratology and single-vision spectacle lens wear, respectively, were analyzed post hoc. The relationship between changes in mean spherical refractive error (MSE) and axial length (AL) in the control group (spectacle wearers) was assessed and subsequently used to convert changes in AL into changes in MSE for the orthokeratology group.

Results: Relatively strong correlations were found between changes in MSE and AL relative to baseline for the control group at all time points, including 0.5-, 1-, 1.5-, and 2-year intervals after lens wear (all P <0.001). The estimated mean changes in MSE (± SD) at 24 months in comparison with baseline for orthokeratology and control groups were -0.77±0.51 and -1.24±0.71 D, respectively. Thus, it is estimated that orthokeratology lenses slow the increase in MSE versus the control by -0.47 D.

Conclusions: This study estimates that orthokeratology lenses reduce myopia progression by -0.47 D after 2 years of lens wear in comparison with spectacle wear. These results might be useful for eye care practitioners engaged in fitting orthokeratology lenses for myopia management.

一种评估角膜塑形镜延缓近视进展效果的方法。

目的：评价角膜塑形隐形眼镜延缓近视进展的效果。方法：对101 ~ 88名6 ~ 12岁、近视度数在-0.50 ~ -5.00 D之间的儿童进行前瞻性数据分析，这些儿童分别完成了2年的角膜塑形镜和单视力眼镜配戴。评估对照组（佩戴眼镜者）平均球面屈光误差（MSE）变化与眼轴长度（AL）之间的关系，并随后将AL变化转化为角膜塑形术组平均球面屈光误差（MSE）变化。结果：在所有时间点，包括镜片佩戴后0.5年、1年、1.5年和2年的间隔，对照组的MSE和AL相对于基线的变化之间存在相对强的相关性（均为p）。结论：本研究估计，与眼镜佩戴相比，角膜塑形镜佩戴2年后可使近视进展减少-0.47 D。这些结果可能是有用的眼科保健从业人员从事配戴角膜塑形镜近视管理。

期刊介绍： Eye & Contact Lens: Science and Clinical Practice is the official journal of the Contact Lens Association of Ophthalmologists (CLAO), an international educational association for anterior segment research and clinical practice of interest to ophthalmologists, optometrists, and other vision care providers and researchers. Focusing especially on contact lenses, it also covers dry eye disease, MGD, infections, toxicity of drops and contact lens care solutions, topography, cornea surgery and post-operative care, optics, refractive surgery and corneal stability (eg, UV cross-linking). Peer-reviewed and published six times annually, it is a highly respected scientific journal in its field.
