We present a nucleus disassembly technique that allows safe debulking of two thirds of the nucleus by removal of a deep, central, equilateral triangular wedge of nucleus with no manipulation or rotation. The resulting equilateral triangular wedge-shaped cavity yields 3 points of weakness at each corner that facilitate cracking the remaining peripheral nuclear rim into 3 equal segments. Each segment is easily gripped by short bursts of phaco power and pulled into the central cavity for safe endocapsular phacoemulsification, an approach that protects the cornea. This technique is applicable to most cataracts regardless of consistency. It prevents zonular stress by avoiding manipulation or rotation of the nucleus in cases in which zonular weakness is a concern. The technique was used in 95 consecutive eyes, with no posterior capsule tears, vitreous loss, or zonule disturbance.
我们提出了一种核分解技术，该技术可通过切除深层、中央等边三角形核楔，在不进行操作或旋转的情况下安全地去除三分之二的核。所形成的等边三角形楔形腔在每个角处产生3个薄弱点，便于将剩余的周边核边缘裂成3个相等的部分。每个部分通过短时间的超声乳化能量脉冲很容易被夹住，并被拉到中央腔进行安全的囊内超声乳化，这种方法可保护角膜。该技术适用于大多数白内障，无论其质地如何。在存在悬韧带薄弱问题的情况下，它通过避免对核进行操作或旋转来防止悬韧带应力。该技术连续应用于95只眼睛，未出现后囊破裂、玻璃体丢失或悬韧带紊乱。
