The purpose of this study was to compare phacoemulsification energy parameters during torsional phacoemulsification with or without the use of intelligent phacoemulsification (IP) software.
One hundred and twenty-eight eyes with nuclear grades ranging from 1 to 5 were enrolled in this randomized prospective study. Operated eyes were divided into two groups, ie, those operated on using IP software (Group 1, n = 67) and those operated on without IP software (Group 2, n = 61). The two groups were compared in terms of ultrasound energy level, ultrasound energy time, aspiration time, and amount of fluid used during surgery.
Operated eyes were further grouped according to soft (grade 1 and 2, n = 37), medium (grade 3, n = 46), and hard (grade 4 and 5, n = 31) nuclear densities. Both the study and the control groups were similar in distribution of nuclear density (P > 0.05). Cumulative dissipated energy was measured as 14.06 ± 9.92 in Group 1 and 14.22 ± 10.99 in Group 2 (P = 0.92). Total ultrasound time was 49 seconds in Group 1 and 52 seconds in Group 2 (P = 0.58). Although the torsional amplitude used was similar (P = 0.86) when IP was either on (71%) or off (68.4%), aspiration time was found to be 4 minutes 17 seconds in Group 1 (P = 0.86) and 5 minutes and 17 seconds in Group 2 (P = 0.007). Total fluid used was measured as 91 cc (P = 0.86) in Group 1 and 109 cc (P = 0.02) in Group 2.
The new IP software did not cause a difference in ultrasound energy levels. However, the new software was found to be advantageous in regards to fluid use and aspiration time.
本研究的目的是比较在有或没有使用智能超声乳化（IP）软件的情况下，扭转超声乳化过程中的超声乳化能量参数。
128只核分级为1至5级的眼睛被纳入这项随机前瞻性研究。手术眼被分为两组，即使用IP软件进行手术的组（第1组，n = 67）和不使用IP软件进行手术的组（第2组，n = 61）。比较两组在超声能量水平、超声能量时间、抽吸时间和手术中使用的液体量方面的差异。
手术眼根据核密度软（1级和2级，n = 37）、中（3级，n = 46）和硬（4级和5级，n = 31）进一步分组。研究组和对照组在核密度分布上相似（P > 0.05）。第1组的累积耗散能量测量值为14.06±9.92，第2组为14.22±10.99（P = 0.92）。第1组的总超声时间为49秒，第2组为52秒（P = 0.58）。尽管当IP开启（71%）或关闭（68.4%）时使用的扭转幅度相似（P = 0.86），但发现第1组的抽吸时间为4分17秒（P = 0.86），第2组为5分17秒（P = 0.007）。第1组的总液体使用量测量值为91 cc（P = 0.86），第2组为109 cc（P = 0.02）。
新的IP软件在超声能量水平上没有造成差异。然而，发现新软件在液体使用和抽吸时间方面具有优势。
