摘要
目的：评价准分子激光角膜切削术（ＰＲＫ）治疗近视散光的临床效果。方法：对２６０眼近视散光用ＶＩＳＸ２０／２０准分子激光系统治疗并随访一年。结果：术前近视散光为－０．２５～－４．００Ｄ，平均－１．００±０．６２Ｄ；术后６月为－０．０７±０．４０Ｄ；术后１年为－０．０６±０．３９Ｄ。术后较术前散光度明显降低（Ｐ＜０．０５）。术后１年较术后６月散光度更低（Ｐ＞０．０５）。无明显回退现象。结论：ＰＲＫ对近视散光具有理想的治疗效果。
The VISX 20/20 excimer laser was used to treat 260 eyes with myopia and myopic astigmatism of 166 patients. All patients were followed up for one year. The diopter of preoperative astigmatism was from -0.25～-4.00D (-1.00±0.62D). The diopter was lowered to -0.07±0.40D at 6 months postoperatively (P<0.05) and -0.06±0.39D at 12 months postoperatively (P<0.01). Photorefractive keratectomy (PRK) is effective and safe for myopic astigmatism.
