摘要: 为对比周边加深与不加深的放射状角膜切开术(radial keratotomy,RA)矫正近视的效果,对2组29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>0.05).提示:角膜周边加深与不加深RK的术后效果无明显差异。

Abstract: In order to compare the effect of radial keratotomy with identical depth incisions and that with two depths incisions, 29 cases (39 eyes) with centripetal incisions were divided into two groups. The groups were operated with identical depth incisions or two depths incisions respectively. The results were dealt with F test. The equal spherical descended (4.7±0.7)D and the corneal refraction descended (4.5±0.8)D two years after surgery with identical depth incisions. To the surgery with two depth incisions , the equal spherical descended (5.0±1.2)D and the corneal refractive descended (4.4±1.3)D. There was no significant difference between the two groups(P>0.05). The surgical effect of redeepened incisions was same as that of identical depth incisions.

Key words: radial keratotomy, the depth of incisions, effect
