摘要随着准分子激光技术的飞速发展,角膜屈光手术方式的不断衍变,拓宽了手术的适应证.而对于伴有屈光不正的角膜营养不良者,临床上采用准分子激光角膜表面切削术(PRK)或采用乙醇法准分子激光上皮瓣下角膜磨镶术(LASEK)或激光治疗性角膜切削术(PTK)以及准分子激光角膜原位磨镶术(LASIK)进行治疗近期取得较好的效果,但术后的远期疾病复发和病情加重令人担忧,此类疾病是否适合行准分子激光角膜切削术?目前在临床治疗上尚需要明确.本文就该疾病的明确分型及确切诊断阐述了3种类型的角膜颗粒状营养不良的个体化治疗方案,旨在于指导临床合理地应用准分子激光角膜切削技术正确地治疗此类疾病,为患者提供安全、有效、持久满意的效果.

abstractsWith the development of excimer laser technologies, the corneal refractive surgical procedures are improved constantly and the indication of excimer laser keratectomy is expanded. In clinic,PRK or LASEK or PTK or LASIK were performed on the eyes of granular corneal dystrophy with refractive error and the early results were satisfied, but the reoccurrence and server opacity of cornea are worried. Is this corneal disease the indication of excimer laser keratectomy? Nowadays, the exact indication for the disease should be declared in clinic. In this article, the customized treatment nomogram for three types of granular corneal dystrophy is explicated according to the clear classification and exact diagnosis on this disease, in order to apply the excimer laser keratectomy reasonably and correctly for the patient approaching the safe、 effective and long term satisfactory result.
