Multilamellar hydrodissection is the injection of balanced salt solution into multiple lamellae of the lens, cleaving it into a small nucleus and multiple layers of cortex. In phacoemulsification, the smaller nucleus reduces phacoemulsification time, and the thicker bed of cortex provides greater protection for the posterior capsule. In extracapsular extraction, the smaller nucleus can be more readily extracted, which is particularly advantageous when capsulorhexis is performed. Creation of multiple cortical lamellae facilitates their aspiration, either with the phacoemulsification or irrigation/aspiration tips. Multilamellar hydrodissection increases the predictability and safety of phacoemulsification and planned extracapsular cataract extraction.
多层面水分离是将平衡盐溶液注入晶状体的多个层面,将其劈裂成一个小核和多层皮质。在超声乳化术中,较小的核可缩短超声乳化时间,较厚的皮质层可为后囊提供更好的保护。在囊外摘除术中,较小的核更容易摘除,这在进行撕囊时尤其有利。形成多个皮质层便于使用超声乳化或灌吸头进行抽吸。多层面水分离提高了超声乳化和计划性囊外白内障摘除术的可预测性和安全性。
