Experimental study.
Brunescent 2.0 mm human lens cubes were created by an instrument devised for this study. Cubes were tested (10 per test) for time of particle removal (efficiency) and for the number of times the lens particle bounced off the tip (chatter) at 300 mm Hg and 550 mm Hg, 50% and 100% power, and 50% and 100% amplitudes (amplitude for Ozil only).
Of the ultrasound settings, efficiency varied from a mean of 3.3 seconds ± 1.4 (SD) to 50.4 ± 11.7 seconds and chatter from 0.0 to 52.0 ± 16.7 bounces per run. The Ozil-IP was generally more efficient than the Ozil and the Ellips FX more efficient than the Ellips. At optimized values, the Ozil-IP and Ellips-FX were similar. In general, efficiency and chatter were better at 550 mm Hg and at 50% power. The amplitude effect was complex. Efficiency closely correlated with chatter (Pearson r(2) = .31, P<.0001).
Objective comparison of phacoemulsification efficiency and chatter found that optimized Ozil-IP and Ellips-FX were similar in both parameters and in general, both performed better than preceding technology. The study parameters can significantly affect efficiency and chatter, which strongly correlate with each other.

实验研究。
用专门为此研究设计的仪器制作出 Brunescent 2.0 毫米人晶状体立方块。以 300 毫米汞柱和 550 毫米汞柱、50%和 100%功率以及 50%和 100%幅度（仅针对 Ozil）对每个测试 10 个晶状体立方块进行粒子去除时间（效率）和晶状体粒子从尖端弹回次数（颤动）的测试。
在超声设定中，效率从平均 3.3 秒±1.4（SD）变化至 50.4±11.7 秒，每次运行的颤动次数从 0.0 变化至 52.0±16.7 次。Ozil-IP 通常比 Ozil 更有效，而 Ellips FX 比 Ellips 更有效。在优化值下，Ozil-IP 和 Ellips-FX 相似。一般来说，在 550 毫米汞柱和 50%功率下，效率和颤动情况更好。幅度的影响较为复杂。效率与颤动密切相关（Pearson r(2) =.31，P<.0001）。
对超声乳化效率和颤动情况的客观比较发现，优化后的 Ozil-IP 和 Ellips-FX 在这两个参数上相似，总体而言，两者均优于之前的技术。研究参数会显著影响效率和颤动，两者密切相关。
