We describe a lamellar keratoplasty technique to bare Descemet's membrane in which air is injected to detach the central Descemet's. After a partial-thickness corneal trephination is performed, a disposable needle is inserted, deeply and bevel down, into the paracentral corneal stroma and air is injected. In most cases, this forms a large air bubble between Descemet's membrane and the corneal stroma. After anterior lamellar keratectomy is performed, a small opening is made in the air bubble and the remaining stromal layers are lifted with an iris spatula, severed with a blade, and excised with scissors. This technique is faster, safer, and easier to perform than previous methods.
我们描述了一种使后弹力层裸露的板层角膜移植技术，即在其中注入空气以使中央后弹力层分离。在进行部分厚度的角膜环钻术之后，将一次性针头以斜面朝下的方式深深插入角膜旁中央基质，然后注入空气。在大多数情况下，这会在后弹力层和角膜基质之间形成一个大气泡。在前板层角膜切除术完成后，在气泡上开一个小口子，然后用虹膜铲将剩余的基质层掀起，用刀片切断，并用剪刀切除。与以前的方法相比，该技术操作更快、更安全且更容易。
