本文对准分子激光PRK治疗近视眼息者503例的早期临床结果进行分析，近视范围为－2．0至－15．0D，根据术前屈光度不同分为三组，术后随访三个月．结果证实准分子激光是一种安全、有效、预测性较好的治疗近视眼方法．全部病人提高了裸眼视力，绝大部分保持了最佳矫正视力，且没有产生危及视力的并发症．
In this paper, the early clinical results of excimer laser PRK in the treatment of 503 cases of myopia were analyzed. Myopia ranged from -2.0 to -15.0D, and were divided into three groups according to the preoperative refraction. The patients were followed up for 3 months. The results confirmed that excimer laser is a safe, effective and predictive method for the treatment of myopia. All patients improved uncorrected visual acuity, the vast majority maintained the best corrected visual acuity, and did not produce complications that endanger vision.
