PURPOSE
To describe a technique to fixate a dislocated donor lenticule following complicated Descemet stripping automated endothelial keratoplasty (DSAEK) when lenticule attachment has not been successful following previous attempts employing air tamponade due to iris defects and posterior capsule ruptures.
METHODS
In this technique, we fixate the DSAEK lenticule at 2 points using partial-thickness sutures buried in the recipient corneal stroma.
RESULTS
Three complicated DSAEK cases were operated by this technique. The lenticules were totally attached and the corneas remained clear up to the last visit, 6 months after the last procedure.
CONCLUSIONS
Our technique is easy to perform and efficient for fixation of detached lenticules and may also be performed primarily to prevent lenticule detachment in complicated DSAEK eyes.
目的
描述一种在复杂的深板层角膜内皮移植术（DSAEK）后固定脱位供体角膜瓣的技术，当由于虹膜缺损和后囊破裂，先前使用空气填塞的尝试未能成功实现角膜瓣附着时。
方法
在该技术中，我们使用埋入受体角膜基质的部分厚度缝线在两点固定DSAEK角膜瓣。
结果
3例复杂DSAEK病例采用该技术进行手术。角膜瓣完全附着，直至最后一次手术后6个月的最后一次随访，角膜仍保持透明。
结论
我们的技术易于操作，对于固定分离的角膜瓣有效，也可主要用于预防复杂DSAEK眼中角膜瓣的脱离。
