摘要
近视发病率在全球范围内呈逐渐上升趋势,严重影响青少年儿童的眼部健康,引起了巨大的经济和社会效益损失。因此,近视防控工作至关重要且刻不容缓。近年来,角膜塑形镜逐渐在近视防控领域体现出其优越性。目前,角膜塑形镜控制近视发展的原理主要以视网膜远视性光学离焦学说为主,促使近视患者的远视性离焦向近视性离焦漂移从而延缓眼轴增长。其控制近视发展的效果与多种因素相关,包括离焦总量、瞳孔直径、光学区设计及镜片偏心等。角膜塑形镜的广泛使用将有效降低青少年儿童的近视发病率,本文就角膜塑形镜利用离焦技术控制近视发展的原理、离焦量和离焦环位置与近视防控效果的关系等方面进行综述,旨在阐明角膜塑形镜离焦技术在近视防控中的研究进展。
English_abstract The incidence of myopia is gradually on the rise worldwide,which seriously affects the eye health of teenagers and children,causing enormous loss of socioeconomic benefits.As a result,the prevention and control of myopia is crucial and urgent.In recent years,orthokeratology lens have gradually demonstrated its superiority in the field of myopia prevention and control.At present,the principle of controlling the development of myopia by orthokeratology lens is mainly based on the theory of retinal hyperopia optical defocus,which promotes the shift of hyperopic defocus to myopic defocus in myopic patients to curb the growth of the axial length.The effect of controlling the development of myopia is related to various factors,including the total amount of defocusing,pupil diameter,optical zone design,and lens decentration.The widespread use of orthokeratology lenses will effectively reduce the incidence of myopia in teenagers and children.This paper discusses the principle of controlling the development of myopia by the defocus technique of orthokeratology lenses,and the relationship between the amount of defocusing and the position of the defocusing circle and the effect of myopia prevention and control.A specific review was conducted to clarify the research progress on defocus technique of orthokeratology lens in the prevention and control of myopia.
