We describe the technique of femtodelineation for posterior polar cataracts. In this technique, the femtosecond laser is used with a cylindrical pattern of lens division to create multiple cylinders within the lens, which results in sharply demarcated layers. The number, size, and depth of the cylinders can be controlled by the surgeon using the live anterior segment optical coherence tomography view. The multiple layers act as mechanical cushions that protect each layer as it is removed. Because of its sharp demarcation, the last epinuclear layer can be easily stripped using a combination of the phaco probe and bimanual irrigation/aspiration. This approach eliminates the need for any type of hydro procedure in posterior polar cataracts. It reduces posterior capsule rupture rates and enhances safety in posterior polar cataract emulsification.

我们描述了用于后极性白内障的飞秒分层技术。在该技术中，飞秒激光以圆柱形晶状体分割模式使用，在晶状体内创建多个圆柱体，从而形成界限清晰的层。外科医生可通过实时眼前节光学相干断层扫描视图控制圆柱体的数量、大小和深度。多层起到机械缓冲作用，在每层被移除时提供保护。由于其界限清晰，使用超声乳化探头和双手灌注/抽吸相结合的方法，可轻松剥离最后一层核上皮质。这种方法消除了后极性白内障中任何类型的水分离操作的必要性。它降低了后囊膜破裂率，提高了后极性白内障乳化的安全性。
