准分子激光上皮瓣下角膜磨镶术治疗超高度近视疗效分析

A clinical analyse of effect of laser subepithelial keratomileusis on intense myopia

目的探讨准分子激光上皮瓣下角膜磨镶术(LASEK)治疗超高度近视的安全性和有效性。方法对73例(134眼)超高度近视进行LASEK手术治疗。随访12个月,观察手术前后的视力、屈光度、眼压及Haze的变化。结果术后随访12个月,裸眼视力达到术前最佳矫正视力或更好者占61·9%;屈光不正度数在1·00D以内者占89·6%;术后结果与术前比较,差异有显著性(P<0·01)。所有患眼的Haze都控制在2级之内,其中0级占83·6%。结论LASEK是治疗超高度近视一种安全有效的手段。

OBJECTIVE To investigate the effectiveness and safety of laser subepithelial keratomileusis （LASEK） for the correction of intense myopia.METHODS LASEK were run on 134 eyes of 73 patients with intense myopia.All were followed for 12 months. Before and after treatment visual acuity, refraction, intraocular pressure and Haze were observed.RESULTS The visual acuity at 12 month after operation wasn＇t worse than the best corrected visual acuity （BCVA） before operation in 83 eyes （61.9 %） .The refraction degree after operation wasn＇t more than ± 1.00 D in 89.6 % of all the eyes. The result after operation was significantly better than that before operation （ paired t- test, P〈0.01） .Haze of all patients was under control at 2 grade below, the percent of 0 grade was 83.6 %. CONCLUSIONS LASEK has good stability and predictability, and it is an effective and safe method for the correction of intense myopia. But some questions need solve still.
