摘要
目的评价准分子激光角膜上皮瓣下磨镶术(LASEK)治疗中、高度近视的临床效果。方法应用美国VISXstarS4准分子激光仪行LASEK手术治疗中、高度近视患者256例460眼,平均术前等值球镜为-7.21±3.56D(-5.00～-11.00D),平均角膜厚度522μm(462～530μm),观察术中及术后上皮瓣厚度、术后裸眼视力、术后症状、屈光度和角膜混浊程度,平均随访时间为12个月。结果术后6个月8例出现上皮下混浊1级,其中,8例出现不同程度的屈光回退;术后屈光度及裸眼视力均在6个月内趋于稳定;角膜上皮瓣的厚薄与是否戴接触镜有关,与戴接触镜时间长短有关,配戴10年以上接触镜者角膜上皮明显变薄。结论LASEK治疗中高度近视疗效确切、安全。高度近视手术后haze发病率低,无明显屈光回退发生。
Objective To evaluate the clinical efficacy of Laser-assisted subepithelial keratomileusis （LASEK） for treatment of moderate and high myopia. Method LASEK was performed for 256 cases with moderate and high myopia of spherical equivalent of-5.00D to -11.00D （-7.21 ± 3.56D）, The average corneal thickness wasS18μm （462-530 μm）. The average follow-up period was 12 months, the intraoperative corneal thickness and postoperative visual acuity, diopter and haze were investigated. Result Three months after the surgery, haze was observed in 8 of the eyes and regression was found among 8 of them. The diopter and uncorrected visual acuity was stable six months after the surgery. The thickness of the flap is related to whether wearing contact lens or not and related to the time of wearing contact lens. The flap is thinner for people who have worn contact lens for more then ten years. Conclusion LASEK is effective and safe for moderate and high myopia. The incidence of haze for high myopia is low and no obvious regression was found.
