为对比周边加深与不加深的放射状角膜切开术 (radialkeratotomy ,RA)矫正近视的效果 ,对 2组 2 9例 39眼进行回顾分析。结果显示 ,术后 2年同一深度组等效球镜下降 ( 4 .7± 0 .7)D ,角膜屈光力下降 ( 4 .5± 0 .8)D ;周边加深组等效球镜下降 ( 5 .0± 1 .2 )D ,角膜屈光力下降 ( 4 .4± 1 .3)D。 2组病人等效球镜及角膜屈光力下降平均值无明显差异 (P >0 .0 5 )。提示 :角膜周边加深与不加深RK的术后效果无明显差异。
To compare the effects of peripheral keratosis with or without radial keratotomy (RA) on correction of myopia, 29 cases (39 eyes) in two groups were retrospectively analyzed. The results showed that in the same depth group at 2 years after operation, the spherical equivalent decreased (4.7 ± 0.7) D and the corneal refractive power decreased (4.5 ± 0.8) D, while the equivalent spherical scope decreased (5 .0 ± 1 .2) D, corneal refractive power decreased (4 .4 ± 1.3) D. There was no significant difference between the two groups in the equivalent spherical and corneal refractive power (P> 0.05). Tip: Peripherally corneal deepening and no deepening RK postoperative effects no significant difference.
