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. |
