对比不同设计离焦镜对青少年近视及散光影响OA

Objective Comp are the effects of three different types of design aspheric lenses(DIMS,HAL,and HORI)on the changes of myopia and astigmatism in adolescents.Methods A total of 207 adolescent myopic patients were selected and divided into the DIMS group(68 cases),HAL group(60 cases),HORI group(28 cases),and single-vision spectacle lenses control group(51 cases)based on the type of spectacle lenses.The patients were followed up for 12 months to monitor the changes in SER,AL,DC,and AST.Results After 3 months,the AL growth amounts of the three types of aspheric lenses were all lower than those of the SVL group;the AST growth amount of the DIMS group was higher than that of the other three groups.After 6 months,the SER growth amplitude of the HAL group was lower than that of the DIMS group and the SVL group;the AL growth amounts of the HAL group and the HORI group were lower than those of the DIMS group and the SVL group,while there was no significant difference between the DIMS group and the SVL group;there was no difference in DC growth amounts among the four groups;the AST growth amount of the DIMS group was high-er than that of the HAL group and the HORI group.After 12 months,the SER growth amplitudes of the three types of aspheric lenses were all lower than those of the SVL group;the AL growth amounts of the HAL group and the HORI group were lower than those of the DIMS group and the SVL group,while there was no significant difference between the DIMS group and the SVL group;the DC growth amount of the DIMS group was higher than that of the HAL group and the HORI group;the AST growth amount of the DIMS group was higher than that of the HAL group.Conclusions The three types of aspheric lenses outperform the single-vision lenses in terms of myopia control.Among them,HAL and HORI have more significant myopia control effects and have less impact on astigmatism.
