A number of studies regarding the effect of orthokeratology (OK) on myopia progression have been published and shown that it can slow myopia progression in school-aged children. Recently, OK has been considered to be one of the most effective optical treatments for myopia control. This article reviewed the peer-reviewed literature on the efficacy of OK for myopia control. Although it cannot halt myopia progression completely, the inhibitory effect on axial elongation for 2 years has been reported to be from 32% to 63%, as compared with single-vision spectacles and contact lenses. In addition, the efficacy and acceptable safety have been confirmed even in several long-term studies up to 10 years. However, the possibility of a rebound phenomenon in myopia progression after OK discontinuation remains unknown. It is also unclear how long the treatment should be continued to attain the maximum benefit in each patient. In the near future, further research including assessment of rebound phenomenon should be conducted with longer follow-up periods in more diverse populations.
已有多项研究探讨角膜塑形术（orthokeratology，OK）对近视进展的影响，结果表明 OK 可减缓学龄儿童的近视进展。最近，OK 被认为是控制近视最有效的光学治疗方法之一。本文综述了 OK 控制近视的疗效的同行评议文献。尽管 OK 无法完全阻止近视进展，但据报道，2 年内对眼轴伸长的抑制作用为 32%至 63%，与单焦框架眼镜和软性隐形眼镜相比。此外，即使在长达 10 年的几项长期研究中，也证实了其疗效和可接受的安全性。然而，OK 停止后近视进展出现反弹的可能性尚不清楚。对于每个患者，要达到最大获益，治疗应持续多长时间也尚不清楚。在不久的将来，应该在更多样化的人群中进行包括评估反弹现象的研究，随访时间应更长。
