Abstract

UNLABELLED

We describe the white ring sign, which differentiates the posterior and anterior lenticular planes in small-incision lenticule extraction. The sign identifies the plane of dissection by the anteroposterior relationship between the dissecting instrument and the circular white light reflected from the lenticular side cut. Differentiating the planes enables the surgeon to dissect the anterior plane before the posterior plane, which facilitates smooth lenticule extraction and prevents complications such as cap tears, partial lenticule dissection, and a torn lenticule.

摘要

未加标签

我们描述了一个白色环征，它可以区分小切口晶状体切除术的晶状体前后平面。这个征象通过切割晶状体侧时器械与从晶状体侧反射回来的圆形白色光线之间的前后关系来识别分离平面。区分平面可以使外科医生在前平面分离后平面，从而使晶状体的顺利提取变得更加容易，并防止诸如瓣撕裂、部分晶状体分离和晶状体撕裂等并发症的发生。
