To evaluate the success of using a cannula for descemetic deep anterior lamellar keratoplasty (dDALK) and the frequency of Descemet perforation using the new Sarnicola deep anterior lamellar keratoplasty (DALK) cannula and spatula.
Retrospective study of medical records of 28 eyes of 28 patients who underwent the DALK procedure between December 2008 and February 2009 using the blunt Sarnicola spatula and cannula. Main outcomes analyzed were the frequency of dDALK and pre-dDALK, the frequency of big-bubble and air-visco bubble formation, and the frequency of Descemet rupture during the procedure.
In 26 cases (93%), we achieved dDALK dissection; 2 cases (7%) were pre-dDALK. Big-bubble formation occurred in 24 cases (86%); in 2 cases (7%), an air-visco bubble was formed. No perforations of Descemet membrane occurred during air injection in an attempt to form a big bubble. A rupture of Descemet membrane occurred in 1 case (3.5%) during peripheral stromal excision.
The smooth Sarnicola DALK spatula and cannula facilitate a high percentage of dDALK and make the maneuver more manageable compared to air injection with a needle.
评估使用套管进行去内皮深前弹力层角膜移植术（dDALK）的成功率，以及使用新的 Sarnicola 深前弹力层角膜移植术（DALK）套管和刮刀发生 Descemet 穿孔的频率。
回顾性研究了 2008 年 12 月至 2009 年 2 月期间 28 例 28 只眼接受 DALK 手术的病历，使用钝性 Sarnicola 刮刀和套管。主要分析的结果是 dDALK 和预 dDALK 的频率、大泡和空气粘弹泡形成的频率，以及在手术过程中发生 Descemet 破裂的频率。
在 26 例（93%）中，我们成功地进行了 dDALK 分离；2 例（7%）为预 dDALK。24 例（86%）形成大泡；2 例（7%）形成空气粘弹泡。在试图形成大泡时，空气注入不会导致 Descemet 膜穿孔。在进行周边基质切除时，1 例（3.5%）发生了 Descemet 膜破裂。
与使用针进行空气注射相比，光滑的 Sarnicola DALK 刮刀和套管更有利于实现高比例的 dDALK，并且使操作更易于管理。
