研究目的:

拟通过一项前瞻性、随机、单盲、自身对照的临床试验,系统评价优化RC设计的角膜塑形镜在延缓儿童近视进展(眼轴长度)方面的有效性和安全性,验证优化RC设计是否通过增强周边离焦信号产生更优的近视控制效果。  

Objectives of Study:

This study intends to conduct a prospective, randomized, single-blind, self-controlled clinical trial to systematically evaluate the efficacy and safety of orthokeratology lenses with optimized RC (reverse curve) design in slowing myopia progression (axial length elongation) in children, and to verify whether the optimized RC design produces superior myopia control effects through enhanced peripheral defocus signals.
