准分子激光治疗近视眼三个月疗效观察

A Three month Follow up Study of Excimer Laser Photorefractive Keratectomy for Myopia

为考查准分子激光屈光性角膜切削术（ＰＲＫ）治疗近视眼的临床效果，作者对该院经治，并有三个月随访资料的１４５例进行了总结。结果：该组患者术前屈光度为－１．５～－１１．５Ｄ，裸眼视力有１３７例在０．１以下占９４％，０．５以下８例占６％。术后一个月时裸眼视力在１．０及１．０以上者占６６％，有９８％的患者裸眼视力达到０．５以上，平均屈光度为＋０．９８±０．８８Ｄ。术后三个月时有７２％的患者裸眼视力在１．０及１．０以上，９３％的患者裸眼视力恢复到０．５以上，平均屈光度为－０．１３±１．０９Ｄ。全组患者均无严重并发症发生，表明ＰＲＫ手术是一种有效、安全和预测性较好的治疗近视眼方法。

In order to evaluate the efficacy of photorefractive keratectomy(PRK) in the treatment of myopia,we summed up and analysed the 3 month follow up data on 145 cases treated in our hospital.Prior to PRK,refractive dioptal was -1.5 to -11.5;visual acuity was less than 0.1 in 137 cases(94%) and less than 0.5 in 8 cases(6%). One month after operation,the mean refractive dioptal was +0.98±0.88;visual acuity increased to≥1.0 in 95 cases (66%) and to≥ 0.5 in 142 cases(98%).Three months after operation,the mean refractive dioptal was -0.13±1.09;visual acuity increased to≥1.0 in 104 cases(72%) and to ≥0.5 in 135 cases(93%).There was no severe complication noted in all cases.The results demonstrate that PRK is and effective,safe and predictable treatment for myopia.
