准分子激光角膜表面切削术治疗近视的疗效分析
A clinical report of excimer laser photorefractive keratectomy in myopia
【摘要】 应用美国CHIRON公司keracor117型准分子激光治疗仪对68例130眼近视患者行PRK治疗。术前屈光度(等值球镜)为-2.00—-9.75D(x±s:-5.11±1.81D)散光度0—-4.0D。结果:术后3—6个月残留屈光度为+0.08±0.29D,裸眼视力≥0.8者占94.2%,≥1.0者占90.4%。术前屈光度-2D—-6D患眼,术后3—6个月裸眼视力≥0.8者占95.2%,≥1.0者占94.2%;术前屈光度-6.25D—-9.75D者,术后3—6个月裸眼视力≥0.8者占91.7%,≥1.0占65.4%。实际矫正度数在预测矫正度±0.5D范围内者占84.6%,0.8%的术眼有2级以下的角膜上皮下雾状混浊,1.5%术眼角膜有丝状物,1.5%术眼用药后一过性眼压升高,最佳矫正视力下降1行者占5.2%。结论:PRK治疗中低度近视是一种安全,有效的手术方法。其稳定性好,预测性强,值得临床应用。但术后应注意护理及随访。
【Abstract】 o evaluate the therapeutic effects of Excimer Laser photorefractire Keratectomy(PRK) for correction of myopia.With Keracor117 excimer laser,PRK was performed on 130 eges of 68 cases with myopia of -200 to-975 diopters (mean,-511±181D)and the hightest astigmatism -400D. Results:The mean refraction was +008±029D after 3 to 6 months postoperatively.942% uncorrected vision was more than 08,904% more than 10 In the first group (myopes below-600D),952% uncorrection vision was more than 08.942% more than 10. For the second group (myopes over-600D),917% uncorrected vision was more than 08,654% more than 10.Haze is main complication in PRK. Conclusions PRK is a safe,effective,stable,predictable method to treat myopia (especially for myopes below-600D),posteroperative care and followup should be servesesed.
