Progressive hyperopia is a common complication following radial keratotomy.
Ten eyes of ten consecutive patients with hyperopia after radial keratotomy between +1.75 and +4.00 diopters (D) were treated with the hyperopia module of the Nidek Model EC-5000 excimer laser. The mean preoperative uncorrected visual acuity was 0.38 (20/60+).
After excimer laser photorefractive keratectomy (PRK), mean uncorrected visual acuity improved to .72 (20/30+). No complications occurred with the exception of one eye with haze greater than 2+.
PRK for hyperopia is a valuable method for correcting hyperopia after radial keratotomy.
进行性远视是放射状角膜切开术后常见的并发症。
连续10例放射状角膜切开术后远视患者的10只眼接受了尼德克EC - 5000型准分子激光远视模块治疗。术前平均未矫正视力为0.38（20/60+）。
准分子激光屈光性角膜切削术（PRK）后，平均未矫正视力提高到0.72（20/30+）。除1只眼出现大于2+的 haze外，未发生其他并发症。
PRK治疗远视是放射状角膜切开术后矫正远视的一种有价值的方法。
