我们报道了移动气泡征在深板层角膜移植术(deep anterior lamellar keratoplasty,DALK)中的应用。这一体征见于99%以上的患者。有晶状体的圆锥角膜是DALK最主要的适应证,这一体征对这类患者非常有用。我们认为对手术方法的小改进将帮助医师缩短此类手术的学习过程,避免前房穿透在手术最后阶段的发生。

·Here we describe shifting bubble sign in manual dissection of deep anterior lamellar keratoplasty(DALK).This sign can be noticed in more than 99% of patients.It is very useful in phakic keratoconic eyes,the leading indication for DALK.We believe that our small modification can help surgeons early in learning curve to avoid inadvertent anterior chamber penetration during the final stages of DALK.
