We present 3 cases of progressive keratoconus in the host after penetrating keratoplasty PKP that were treated with a wide crescentic excision of the diseased tissue in the host cornea guided by Orbscan II topography (Bausch & Lomb). In all cases, the procedure resulted in a more regular corneal shape with a marked reduction in astigmatism, preventing the need for repeat PKP
我们报告了3例穿透性角膜移植术（PKP）后宿主发生进行性圆锥角膜的病例，这些病例采用Orbscan II地形图（博士伦公司）引导下对宿主角膜病变组织进行宽新月形切除的方法进行治疗。在所有病例中，该手术均使角膜形状更加规则，散光显著降低，从而避免了再次进行PKP的必要。
