摘　　要：目的分析青少年近视患者在配戴角膜塑形镜和框架眼镜后对AC/A的不同影响。方法对23例(46眼)配戴角膜塑形镜和34例(68眼)戴框架眼镜的青少年近视患者,观察1年后两组患者的屈光度和AC/A值。结果戴镜1年后,角膜塑形镜组平均屈光度增加了0.35±0.25D,框架镜组平均屈光度增加了0.82±0.36D,两组差异有统计学意义(P<0.05)。角膜塑形镜组平均AC/A值降低了0.83±0.23,框架镜组增加了0.12±0.06,两组差异有统计学意义(P<0.05)。结论角膜塑形镜可以有效减缓青少年的近视加深,降低AC/A值,使患者的调节与集合的关系更加协调。Objective To analyse different effects on AC/A between after wearing orthokeratology lenses and glasses in juvenile myopia patients. Methods 23 patients （46 eyes） received orthokeratology lens trement and 34 pa-tients （68 eyes） received glasses in adolescent myopia patients,and then diopter and AC/A values were measured af-ter 1 year. Results The average diopter value increased 0.35 ± 0.25D in orthokeratology lens group to compare with 0.82 ± 0.36D in wearing glasses group after 1 year, and there was statistically significant difference （P〈0.05） ; The average AC/A values decreased 0.83±0.23 in orthokeratology lens group to compare with 0.12 ± 0.06 in wearing glasses group after 1 year, and there was statistically significant difference （P〈0.05） . Conclusions Orthokeratology lens can effectively slow down the progression of myopia in adolescent patients, and reduce AC/A values to balance between the accommodation convergence and accommodation.
