准分子激光治疗近视眼疗效观察

One year follow up of excimer laser photorefractive keratectomy for myopia

目的了解准分子激光屈光性角膜切削术（ＰＲＫ）治疗近视眼的临床效果。方法对有１ａ随访资料的５６９人１０８２只眼ＰＲＫ治疗进行分析和总结。结果术后１ａ时，第１组（＜－６．００Ｄ），第２组（－６．２５～－９．００Ｄ）和第３组（＞－９．２５Ｄ）裸眼视力在１．０及１．０以上分别为７５．３４％、６１．３８％和１１．３９％，裸眼视力达到０．５以上３组病人的比例分别是９２．２４％、８６．２１％和４１．７７％；３组病人术后屈光度在±１．００Ｄ范围内的比例分别是８２．６５％、７４．４８％和１５．２％。没有严重并发症发生。结论ＰＲＫ手术是一种安全。

ObjectiveTo evaluate clinical effects of myopia treated with PRK.Methods569 patients(1082 eyes) treated with PRK and followed up for 1 a were analysed.ResultsAt 1 a,the uncorrected visual acuity of 1.0 or better in group 1 (<-6.00 D),group 2 ( 6.00～9.00 D) and group 3 (>-9.00 D) were 75.34%,61.38% and 11.39%,respectively.92.24%,86.21%,41.77% of the eyes had an uncorrected visual acuity of 0.5 or better in the groups above,respectively.The postoperative refraction within ±1.00 D were 82.65%,74.48%,15.2%,respectively.For all patients,no severe complications were observed.ConclusionPRK for myopia appears to be effective,predictable and safe.
