摘　　要：离焦学说是目前近视防控的主流学说,从最初的动物研究、临床试验到如今以此学说为理论基础衍生的诸多防控手段(角膜塑形镜、离焦软镜、离焦框架眼镜等)均验证了周边视网膜的近视离焦状态在延缓眼轴增长中的重要性。其中角膜塑形术以其独特的防控效果脱颖而出,归因于角膜塑形术较其他防控手段可诱导更多的周边近视离焦,且该近视离焦主要产生在周边视网膜10°~30°偏心范围内(10°~20°防控效果最强)并呈现颞侧与鼻侧非对称的分布。角膜塑形术后的近视离焦量会在第1晚达到最大,之后1~12个月处于稳定。Defocus theory is the mainstream theory of myopia prevention and control theory,from the initial animal researches and clinical trials to the current prevention and control methods(orthokeratology,defocus soft lens,defocus frame glasses,etc.)derived from this theory have all verified the importance of myopic defocus state of the peripheral retina in delaying the growth of the ocular axis.Among them,orthokeratology stands out with its predominant prevention and control effect,which is attributed to the more peripheral myopia defocus induced than other methods.Moreover,myopic defocus is mainly produced in the peripheral retina within the 10°~30°eccentric range(it achieves the strongest prevention and control effect within 10°~20°eccentric range)and presents the asymmetric distribution of the temporal and nasal sides.Myopic defocus after orthokeratology is at its maximum on the first night and is stable after 1~12 months.
