目的：探讨飞秒激光技术在各种角膜疾病患者穿透性角膜移植术中的应用价值。设计：介入性病例系列。方法：5例45 ~ 81岁的患者于2005年9月采用20/10 Perfect Vision Femtec飞秒激光系统行穿透性角膜移植术。患者有颗粒状角膜营养不良、富氏内皮营养不良、圆锥角膜和伴内皮代偿丧失的疱疹性角膜炎。采用组织病理学方法分析供、受体角膜的切割质量。所有手术均无并发症发生。在所有病例中，供体角膜的直径为8.0或8.1 mm，受体角膜的直径为7.8 mm。在所有角膜上都实现了完整的穿孔切口。供体和受体标本组织学显示切口直、光滑，无任何异常。结论：Femtec飞秒激光可以安全、准确地进行穿透性角膜移植术。术后结果平平。
PURPOSE: To evaluate femtosecond laser technology for penetrating keratoplasty in patients with various corneal diseases.DESIGN: Interventional case series.METHODS: Five patients aged 45 to 81 years underwent penetrating keratoplasty using the 20/10 Perfect Vision Femtec femtosecond laser system in September 2005. Patients had granular corneal dystrophy, Fuchs endothelial dystrophy, keratoconus, and herpetic keratitis with endothelial decompensation. Histopathology was per, formed to analyze the cut quality of donor and recipient cornea.RESULTS. All procedures were performed without any complications. In all cases, the donor cornea was cut with an 8.0 or 8.1 mm diameter and the recipients' cornea with a 7.8 mm diameter. A complete perforating cut was achieved in all corneas. Histology of donor and recipient specimen showed a straight, smooth cut without any abnormalities.CONCLUSIONS: Penetrating keratoplasty can be performed with the Femtec femtosecond laser safely and accurately. The postoperative outcome was uneventful.
