应用激光行上皮下角膜磨镶术30例疗效观察

目的LASEK治疗近视、散光60眼疗效观察.方法30例60跟术前近视屈光度-1.50～-11.00DS,散光-1.50～-2.50 DC,采用20%乙醇浸泡30～35 s制作角膜上皮瓣,激光切削采用NIDEK、EC-5000XⅡ,准分子激光系统.结果术后平均视力1个月0.8～1.0占73.17%,0.5～0.7占26.55%,＜0.5占0.27%;3个月0.8～1.0占76.69%,0.5～0.7占23.30%;6个月0.8～1.0占77.78%,0.5～0.7占21.68%.术后3个月视力与术前矫正视力无显性差距.结论LASEK手术较PRK手术疼痛轻,Haze轻,治疗范围广,较LAsIK手术风险小,隐患少,在激光治疗近视方面是比较安全可选的一种方法.

Clinical efficacy evaluation of 30 cases of lase subepithelial keratomileusis

Objective To evaluate the clinical efficacy of laser-assited subepithelial keratomileusis(LASEK) for treatment of myopia and astigmatism.Methods LASEK was performed for 30 cases(60 eyes) with myopia and astigmatism.The preoperative myopia diopter ranged from -1.50DS to -11.00DS,the astigmatism ranged from -1.50DC to -2.50DC.To make corneal subepithelial valve,eyes were soaked in 20% alcohol for 30 to 35 seconds.It was applied with quasi-molecule laser system.Results The visions with 73.17% were between 0.8 and 1.0 one month post-operatively,26.55% between 0.5 and 0.7,and 0.27% less than 0.5;The average visions with 76.69% were between 0.8 and 1.0 three months post-operatively,and 23.30% between 0.5 and 0.7;The visions with 77.78% were between 0.8 and 1.0 in six months after operation,and 21.68% between 0.5 and 0.7.There were no significant difference between in three months post-operatively and preoperative in corrected visions.Conclusion LASEK induces less pain and HAZE than PRK and LASEK has wider surgery field.Moreover,the risk of LASEK has less risk and less hidden danger than LASIK.In summary,LASEK is one of the safe choices in the treatment of myopia with laser relatively.
