准分子激光上皮瓣下角膜磨镶术治疗近视的疗效观察

目的:评价准分子激光上皮瓣下角膜磨镶术(LASEK)治疗近视的疗效观察。方法:应用日本产。NIDEK EC-5000型准分子激光机对78眼不同程度近视(-1.50-12.00D)行LASEK治疗,术后3-12个月对视力、屈光度及角膜雾样混浊(Haze)进行随访。结果:术后3～12个月96.2％裸眼视力均达到0.5以上,≥1.0者达92.3％,78眼最后一次复查屈光度在±1.00D以内者为74眼,Ⅱ级Haze者为4眼。结论:LASEK是治疗近视的安全有效的方法之一,但尚需临床进一步随访、观察,及基础理论的研究。

Results after Laser Epithelial Keratectomileusis for Myopia

PURPOSE: To study the results of laser epithelial keratectomileusis (LASEK) for myopia. METHODS: LASEK was performed with the Nidek EC-5000 excimer laser. 39 patients (78 eyes) with a refraction of -1.50 to -12.00 diopters were treated and followed for 3-12 months. Postoperrative pain, uncorrected visual acuity (UCVA), refraction, corneal haze, and surgical preference were examined. RESULTS: During 3-12 months follow-up, 96.2% UCVA were above 0.5, 92.3% eyes were at least 1.0 in UCVA. The last refraction were whthin +1.00 D and -1.00 D in 18 eyes except 4 eyes. The II grade haze was found in four eye. CONCLUSIONS: LASEK was one of methods to treat eyes with myopia safely and effectively, but also studied in operation, experiment, and further effect.
