In this paper, we examine the 193 nm excimer laser's efficacy and safety in treating myopic astigmatism. The VISX Twenty/Twenty excimer laser uses aperture elements to effect astigmatic photorefractive keratectomy. In 70 patients with six months follow-up, the average postoperative sphere was -0.14 and the average postoperative cylinder was -0.54. Seventy-one percent of these patients had uncorrected visual acuity of 20/40 or better at six months. In 12 patients with one year follow-up, the average postoperative sphere was -0.05 and the average postoperative cylinder was -0.59. Eighty-three percent of these patients had uncorrected acuities of 20/40 or better; none had a clinically significant loss of best corrected acuity. This investigation demonstrates that the excimer laser can be used to treat myopic astigmatism successfully.
在本文中,我们研究了193纳米准分子激光治疗近视散光的疗效和安全性。VISX Twenty/Twenty准分子激光使用光阑元件进行散光性屈光性角膜切削术。在70例随访6个月的患者中,术后平均球镜度数为-0.14,术后平均柱镜度数为-0.54。这些患者中有71%在6个月时未矫正视力达到20/40或更好。在12例随访1年的患者中,术后平均球镜度数为-0.05,术后平均柱镜度数为-0.59。这些患者中有83%未矫正视力达到20/40或更好;无一例患者的最佳矫正视力出现临床上有意义的下降。这项研究表明,准分子激光可成功用于治疗近视散光。
