To compare the mean cumulative dissipated energy (CDE) in patients having femtosecond laser-assisted or conventional phacoemulsification cataract surgery using 2 different phacoemulsification platforms.
Bascom Palmer Eye Institute, Miami, Florida, USA.
Prospective comparative nonrandomized clinical study.
Consecutive patients were scheduled to have femtosecond laser-assisted cataract surgery with the Lensx laser or conventional phacoemulsification using an active-fluidics torsional platform (Centurion) or torsional platform (Infiniti). The mean CDE and cataract grade were recorded.
The study comprised 570 eyes (570 patients). There was no statistically significant difference in mean age (P = .41, femtosecond group; P = .33, conventional group) or cataract grade (P = .78 and P = .45, respectively) between the active-fluidics and gravity-fluidics platforms. In femtosecond cases (145 eyes), the mean CDE (percent-seconds) was 5.18 ± 4.58 (SD) with active fluidics and 7.00 ± 6.85 with gravity fluidics; in conventional cases (425 eyes), the mean CDE was 7.77 ± 6.97 and 11.43 ± 9.12, respectively. In both femtosecond cases and conventional cases, the CDE was lower with the active-fluidics platform than with the gravity-fluidics platform (P = .029, femtosecond group; P < .001 conventional group). With both fluidics platforms, the mean CDE was significantly lower in the femtosecond group than in the conventional group (both P < .001).
The active-fluidics phacoemulsification platform achieved lower CDE values than the gravity-fluidics platform for conventional cataract extraction. Femtosecond laser pretreatment with the active-fluidics platform further reduced CDE.
比较使用两种不同超声乳化平台的飞秒激光辅助或传统超声乳化白内障手术患者的平均累积消散能量（CDE）。
美国佛罗里达州迈阿密市巴斯科姆·帕尔默眼科研究所。
前瞻性比较非随机临床研究。
连续患者计划接受使用Lensx激光的飞秒激光辅助白内障手术或使用主动流体扭转平台（Centurion）或扭转平台（Infiniti）的传统超声乳化手术。记录平均CDE和白内障分级。
该研究包括570只眼（570例患者）。主动流体平台和重力流体平台之间的平均年龄（飞秒组P = 0.41；传统组P = 0.33）或白内障分级（分别为P = 0.78和P = 0.45）无统计学显著差异。在飞秒手术病例（145只眼）中，主动流体时平均CDE（百分比秒）为5.18±4.58（标准差），重力流体时为7.00±6.85；在传统手术病例（425只眼）中，平均CDE分别为7.77±6.97和11.43±9.1２。在飞秒手术病例和传统手术病例中，主动流体平台的CDE均低于重力流体平台（飞秒组P = 0.029；传统组P < 0.001）。在两种流体平台中，飞秒组的平均CDE均显著低于传统组（均P < 0.001）。
对于传统白内障摘除术，主动流体超声乳化平台的CDE值低于重力流体平台。主动流体平台的飞秒激光预处理进一步降低了CDE。
