准分子激光角膜上皮瓣下磨镶术治疗近视

Treatment of myopia with laser subepithelial keratomileusis

目的:评价准分子激光上皮瓣下角膜磨镶术(laser subep ithelial keratom ileusis,LASEK)治疗近视的效果和安全性。方法:对385例746只眼行LASEK手术,术前球镜屈光度-0.75~16.0 D,柱镜屈光度0^-6.0 D以下。术后随访12个月。结果:术中无并发症发生,术后3个月屈光度基本稳定。术后屈光回退者16眼(2.14%);出现角膜上皮下基质混浊者6眼(8.04%);术后裸眼视力≥1.0者709眼(95%),>0.5<1.0者40眼(5%)。结论:LASEK既解决了LASIK手术禁忌的部分病例,也弥补了PRK手术的不足,是一种安全、有效、预测性好的屈光手术。

Objective： To evaluate the safety and egicacy of laser subepithelial keratomileusis （LASEK） in the treatment of myopia. Methods： The operation of LASEK was performed on 746 eyes in 385 patients with myopia and astigmatism. The follow -up period was 12 months. Results： No complication occurred during operations in all these patients. The diopter was unchangible 3 months after operations. Although some postoperative complications such as haze developed, visual acuity was improved in most patients. Conclusion： LASEK can be performed for the patients not suited for the treatment of LASIK, and it can avoid some disadvantages of PRK. LASEK is a safe and effective treatment method for myopia.
