Photorefraction keratectomy (PRK) was carried out using Nidek EC-5000 eximer laser in patients with myopia of different degree and myopic astigmatism. After 12 months, visual acuity without correction was 0.6-1.0 diopters in all patients with slight myopia, 0.7-1.0 in 95% of patients with medium myopia, and 0.8-1.0 in 86% of patients with high myopia. A lower visual acuity in high myopia was caused by retinal complications of myopia. The results of refraction after PRK depended on the severity of myopia and patient's age. The degree of myopia regression depended on preoperative refraction and was more expressed in high myopia. Young patients developed a more expressed tendency to decrease of postoperative refraction. The results indicate that eximer laser is an effective and reliable tool for correcting myopia of different degree and myopic astigmatism.
使用尼德克EC - 5000准分子激光对不同程度近视和近视散光患者进行了屈光性角膜切削术(PRK)。12个月后,所有轻度近视患者的裸眼视力为0.6 - 1.0屈光度,95%的中度近视患者为0.7 - 1.0,86%的高度近视患者为0.8 - 1.0。高度近视患者视力较低是由近视的视网膜并发症所致。PRK术后的屈光结果取决于近视的严重程度和患者年龄。近视回退程度取决于术前屈光,在高度近视中表现更为明显。年轻患者术后屈光降低的趋势更为明显。结果表明,准分子激光是矫正不同程度近视和近视散光的有效且可靠的工具。
