准分子激光表面切削术治疗近视的临床体会

The clinical experience in the treatment of myopia with surface excimer laser keratectomy

目的探讨准分子激光表面切削手术治疗近视的临床效果和不同手术方法的优点。方法近视980例1906眼分别采用PRK、LASEK和Epi-LASIK手术,观察3种手术方法的效果和主要并发症。结果3种准分子激光表面切削手术方式中LASEK术后反应最轻。术后6个月PRK249眼中217眼(87.15%)达到术前最佳矫正视力,haze和皮质类固醇性高眼压的发生率分别为2.81%和12.23%;LASEK1406眼中1265眼(89.97%)达到术前最佳矫正视力,haze和皮质类固醇性高眼压的发生率分别为2.20%和10.86%;Epi-LASIK251眼中228眼(90.84%)达到术前最佳矫正视力,haze和皮质类固醇性高眼压的发生率分别为1.59%和9.65%。结论准分子激光表面切削技术由于其并发症少且操作方便,是安全、有效、可预测性强的屈光手术。

Objective To explore the clinical effects and advantage of three methods of laser keratectomy in the treatment of myopia. Methods The rate of clinical effects and important syndrome were observed after surgery in the 980 cases of myopia used by PRK, LASEK and Epi-LASIK. Results 217 eyes among 249 eyes （87.15%） used by PRK gained the best corrected visual acuity （BCVA） after surgery six months, in whose the rate of haze and hormonal intraocular hypertension were 2.81% and 12.23% respectively, 1265 eyes among 1406 eyes （89.97%） used by LASEK gained the preoperative BCVE, in whose the rate of haze and hormonal intraocular hypertension were 2.20% and 10.86% respectively;228 eyes among 251 （ eyes （90. 84% ） used by Epi-LASIK gained the preoperative BCVA,in whose the rate of haze and hormonal intraoeular hypertension were 1.59% and 9.65% respectively. Conclusions The surface excimer laser keratectomy is a kind of safe, effective and calculable operation, which has advantage of less syndrome and advantageous manipulation.
