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。方法对221例中、高度近视患者行LASEK手术,平均年龄(22.3±4.0)岁,平均术前等球镜为-8.57±2.16D(-5.00^-11.00D),平均角膜厚度518μm(462~530μm)。平均随访时间为12个月,术中及术后分别观察上皮瓣厚度、视力、屈光度、角膜混浊程度。结果术后3个月4例出现上皮下混浊,其中2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佩戴接触镜有关,与佩戴接触镜时间长短有关,佩戴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） treatment of moderate and high myopia. Methods： LASEK was performed for 221 cases with moderate and high myopia of spherical equivalent of - 5. 00D to - 11.00D （- 8. 57 ± 2. 16D）, the average age was 22. 3 ±4. 0 and the average corneal thickness was 518μm （462- 530 μm）. The average follow-up period was 12 months, the intraoperative corneal thickness and postoperative visual acuity, diopter and haze were investigated. Results： Three months after the surgery, haze was observed in 4 of the eyes and regression was found among 2 of them. The diopter and uncorrected visual acuity was stable six months after the surgery. The thickness of the flap was related to whether wearing contact lens or not and related to the time of wearing contact lens. The flap was thinner for people who have worn contact lens for more than 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 is found.
