59例118只眼行放射状角膜切开术后屈光不正的早期改变进行分析。全部病例术前由专一验光师用睫状肌麻痹剂扩瞳检影验光，并根据其屈光不正情况将其分成轻、中、重度近视及复性近视散光4组。在术后第2周、3个月及9个月时分别再用同一方法验光。发现轻、中度近视组术后裸眼视力均明显提高，近视度明显减少，其屈光度变化在0．25～1．75D之间且保持较稳定状态；高度近视组在1．50～6．25D之间；复性近视散光组在0．50～2．50DCA之间；后两组且不稳定。
Fifty-nine patients (118 eyes) were analyzed for early changes in refractive errors after radial keratotomy. All cases were preoperatively optometrist optometrist with cycloplegic retinoscopy retinoscopy, and according to their refractive errors will be divided into mild, moderate and severe myopia and refraction myopic astigmatism 4 groups. In the second week, 3 months and 9 months after the same method were again optometry. It was found that the visual acuity of uncorrected eyes of mild and moderate myopia group was significantly increased, myopia was significantly reduced, the diopter changes between 0.25 ~ 1.75D and maintain a more stable state; high myopia group at 1.50 ~ 6.25D ; Refraction myopic astigmatism group between 0.50 ~ 2.50DCA; the latter two groups and unstable.
