Ongoing prospective evaluation of radial keratotomy was conducted on 156 eyes of the first 101 consecutive patients. We did a one-year follow-up and compared previously reported six-month findings. All eyes were examined both six months and one year after surgery. Findings obtained by an independent examiner both before and after surgery correlated highly with findings obtained in the surgeon's office. One year after surgery, mean change in spherical equivalent was +4.7 diopters; overall uncorrected distance acuity was 20/20 in 49% of cases and at least 20/40 in 76% of cases. Fifty-eight percent of eyes were within 1.0 D of emmetropia. Visual results showed slight general improvement between six and 12 months; refractive results were stable, except that excessive overcorrection was found to decrease. In this series, radial keratotomy seemed safe and effective one year after surgery.
对连续101例患者的156只眼进行了放射状角膜切开术的前瞻性持续评估。我们进行了为期一年的随访，并比较了之前报告的六个月的结果。所有眼睛均在术后六个月和一年进行检查。手术前后由独立检查者获得的结果与在外科医生办公室获得的结果高度相关。术后一年，等效球镜度的平均变化为+4.7屈光度；总体未矫正远视力在49%的病例中为20/20，在76%的病例中至少为20/40。58%的眼睛在正视眼的1.0 D范围内。视觉结果在6至12个月之间有轻微的总体改善；屈光结果稳定，只是发现过度矫正有所减少。在本系列中，放射状角膜切开术在术后一年似乎是安全有效的。
