本文对３２４例６１８眼实施放射状角膜切开术。术前平均屈光度为－６．２６Ｄ，平均视力为０．１７；术后平均降低５．３３Ｄ，其中低度近视降低２．５３Ｄ，中度近视降低４．５８Ｄ，高度近视降低５．９４Ｄ，超高度近视降低６．９１Ｄ；视力平均为１．０４；摘镜率为９１％，其中正视率占１７．６７％，低矫占３７％，过矫占５．３３％，散光增加者占８．２４％；眩光发生率１１％；并对影响手术效果的诸因素进行了分析，对各参数的相关性进行了初步的探讨。 324 cases of 618 eyes performed radial keratotomy. Preoperative average refractive power was -6.26D, the average visual acuity was 0.17; postoperative average reduction of 5.33D, including low myopia decreased 2.53D, moderate myopia decreased 4.58D, high myopia decreased 5.94D, super High myopia decreased 6.91D; visual acuity average 1.04; pick mirror rate was 91%, of which the orthoptic rate accounted for 17.67%, low correction of 37%, overcorrection accounted for 5.33%, astigmatism accounted for 8%. 24%; the incidence of glare 11%; and the factors that affect the effect of the surgery were analyzed, the correlation between the parameters were initially discussed.
