To compare the cumulative dissipated energy (CDE), aspiration time and estimated aspiration fluid utilized during phacoemulsification cataract surgery using two phacoemulsification systems .
A total of 164 consecutive eyes of 164 patients undergoing cataract surgery, 82 in the active-fluidics group and 82 in the gravity-fluidics group were enrolled in this study. Cataracts graded NII to NIII using LOCS II were included. Each subject was randomly assigned to one of the two platforms with a specific configuration: the active-fluidics Centurion phacoemulsification system or the gravity-fluidics Infiniti Vision System. CDE, aspiration time (AT) and the mean estimated aspiration fluid (EAF) were registered and compared.
A mean age of 68.3 ± 9.8 years was found (range 57-92 years), and no significant difference was evident between both groups. A positive correlation between the CDE values obtained by both platforms was verified (r = 0.271, R = 0.073, P = 0.013). Similarly, a significant correlation was evidenced for the EAF (r = 0.334, R = 0.112, P = 0.046) and AT values (r = 0.156, R = 0.024, P = 0.161). A statistically significantly lower CDE count, aspiration time and estimated fluid were obtained using the active-fluidics configuration when compared to the gravity-fluidics configuration by 19.29, 12.10 and 9.29%, respectively (P = 0.001, P < 0.0001 and P = 0.001).
The active-fluidics Centurion phacoemulsification system achieved higher surgical efficiency than the gravity-fluidics Infiniti IP system for NII and NIII cataracts.
比较使用两种超声乳化系统进行白内障超声乳化手术时的累积耗散能量（CDE）、抽吸时间和估计抽吸液量。
本研究纳入了164例接受白内障手术患者的164只连续眼睛，其中82只属于主动流体学组，82只属于重力流体学组。纳入使用LOCS II分级为NII至NIII级的白内障。每个受试者被随机分配到两种具有特定配置的平台之一：主动流体学的Centurion超声乳化系统或重力流体学的Infiniti视觉系统。记录并比较CDE、抽吸时间（AT）和平均估计抽吸液量（EAF）。
发现平均年龄为68.3±9.8岁（范围57 - 92岁），两组之间无明显差异。验证了两个平台获得的CDE值之间存在正相关（r = 0.271，R = 0.073，P = 0.013）。同样，EAF（r = 0.334，R = 0.112，P = 0.046）和AT值（r = 0.156，R = 0.024，P = 0.161）也存在显著相关性。与重力流体学配置相比，使用主动流体学配置时，CDE计数、抽吸时间和估计液体量在统计学上显著降低，分别降低了19.29%、12.10%和9.29%（P = 0.001，P < 0.0001和P = 0.001）。
对于NII和NIII级白内障，主动流体学的Centurion超声乳化系统比重力流体学的Infiniti IP系统具有更高的手术效率。
