桥状穿透性角膜移植术

  [适应证]

  1.单疱病毒性角膜炎活动期或化脓性角膜感染,药物治疗无效,不得不行穿透性角膜移植者。

  2.角膜大穿孔或角膜瘘者,术前无前房者。

  3.大泡性角膜病变及内皮功能不良造成的一些植床比植片明显厚的病例,可减少植片后膜,虹膜或玻璃体与植片粘连的并发症,提高植片的透明率。

  [术前准备及麻醉]

  术前准备、麻醉同部分穿透性角膜移植术。

  [手术步骤]

  1.取移植片,一般不小于7mm,因为7mm的植片常常有1mm的环形混浊带。

  2.制移植孔略大于角膜病灶深达角膜厚度3/4(近后弹力层)的板层植床。以较前植孔径小1~2mm的环钻,在此板层植床中央,钻透板层,或只钻透一部分,采用角膜剪完成(图1)。
