This paper presents a hydrodissection technique performed with high-speed pulse injection of only 0.1 cc liquid and assess its efficacy, safety, and the level of reduction in posterior capsule rupture complications in phacoemulsification cataract surgery. The kinetic energy of moving objects is directly proportional to the mass and to the square of its velocity. The high energy obtained by high-speed pulse injection of a small amount of liquid ensures highly effective dissection. Since the amount of liquid is very small, the increase in intraocular pressure and the risk of rupture in the posterior capsule due to anterior capsular block are greatly reduced. More importantly, several rotations of the lens material in the capsule with effective hydrodissection facilitate the phases of phacoemulsification and irrigation/aspiration. As most capsule ruptures occur during these phases, the complication rate is thus reduced.
本文介绍了一种仅以0.1毫升液体高速脉冲注射进行水分离的技术，并评估其在白内障超声乳化手术中的疗效、安全性以及后囊破裂并发症的降低程度。运动物体的动能与质量及其速度的平方成正比。通过少量液体的高速脉冲注射获得的高能量确保了高效的分离。由于液体量非常少，眼内压的升高以及前囊阻滞导致后囊破裂的风险大大降低。更重要的是，有效的水分离使晶状体物质在囊袋内进行几次旋转，这有利于超声乳化和冲洗/抽吸阶段。由于大多数囊袋破裂发生在这些阶段，因此并发症发生率降低。
