业已证实放射状角膜切开术是有效而安全的。但大多数报告结果均来自术后1～2年的观察。本文作者对放射状角膜切开术后3～4年的结果进行了研究及评价。论证了放射状角膜切开术后第2年和第4年病人视力及屈光的改变。选例及方法:本文对1979～1981年行放射状角膜切开术的79例(109眼)进行了检查。对55例81眼(74.3%),在术后8～18个月(1年随访)进行了检查,并在术后31～57个月(4年随访)再次检查。随访检查间隔时间为18.1～45.9个月,平均为33.6个月。仅有7例间隔少于24个月。对未矫正视力的患者作了散瞳验光及角膜曲率测量。
Radial keratotomy has proven effective and safe. However, most of the reported results are from 1 to 2 years after surgery. The author of the radial keratotomy 3 to 4 years after the results were studied and evaluated. Demonstrated the radial corneal incision in 2 years and 4 years of patients with visual acuity and refractive changes. SELECTIONS AND METHODS: 79 cases (109 eyes) undergoing radial keratotomy from 1979 to 1981 were examined. Fifty-one eyes (74.3%) were examined in 55 eyes (74.3%) at 8-18 months (1 year follow-up) and again at 31-57 months (4-year follow-up). Follow-up examination interval was 18.1 ~ 45.9 months, an average of 33.6 months. Only 7 patients separated by less than 24 months. Mydriatic optometry and corneal curvature measurements were performed on uncorrected vision.
