We report two-year follow-up findings on 142 (91%) of the first 156 radial keratotomies performed. The results are contrasted with our earlier six-month and one-year results and with findings from other studies. Mean spherical equivalent before surgery was -5.0 diopters and two years after surgery was -0.10 D; 51% of the eyes were within 1 D of emmetropia. Uncorrected distance acuity was 20/200 or worse in 96% of the eyes before surgery. At two years, 39% had 20/20 acuity or better and 76% had 20/40 or better. At one year, 49% had 20/20 acuity and 76% had 20/40 acuity or better. Refractive results between one and two years showed an overall increase in mean spherical equivalent of 0.23 D. Our results indicate radial keratotomy to be relatively safe and effective two years after surgery.
我们报告了首批156例放射状角膜切开术中142例（91%）的两年随访结果。将这些结果与我们早期的六个月和一年的结果以及其他研究的结果进行了对比。术前平均球镜当量为-5.0屈光度，术后两年为-0.10 D；51%的眼睛在正视眼1 D范围内。术前96%的眼睛未矫正远视力为20/200或更差。两年时，39%的眼睛视力达到20/20或更好，76%的眼睛视力达到20/40或更好。一年时，49%的眼睛视力达到20/20，76%的眼睛视力达到20/40或更好。一到两年间的屈光结果显示平均球镜当量总体增加了0.23 D。我们的结果表明，放射状角膜切开术在术后两年相对安全有效。
