To evaluate the efficiency of a hybrid tip in removing cataract grade 3 and 4 in high and low intraocular pressure (IOP) settings.
This was a randomized, prospective, double-arm contralateral eye study. One randomized eye of each subject had phacoemulsification with high IOP settings (50 mmHg) while the other eye had phacoemulsification with low IOP settings (20 mmHg). Operative endpoints included phaco time, aspiration time, fluid use, cumulative dissipated energy (CDE), total case time, total torsional time, and total longitudinal time. Postoperative endpoints included central corneal thickness (CCT), and IOP.
A total of 102 eyes (51 patients) completed the study. Phaco time in grade 3 and grade 4 cataracts were 38.4 ± 9.6 s and 44.1 ± 9.9 s in the high group, respectively, and 38.9 ± 8.6 s and 46.3 ± 11.0 s in the low group, respectively. Aspiration time in grade 3 and grade 4 cataracts were 95.3 ± 21.2 s and 111.8 ± 32.8 s in the high group, respectively, and 105.4 ± 27.0 s and 108.6 ± 23.1 s in the low group, respectively. Fluid volume used in grade 3 and grade 4 cataracts were 39.2 ± 6.8 mL and 45.2 ± 10.8 mL in the high group, respectively, and 38.3 ± 7.3 mL and 43.2 ± 8.0 mL in the low group, respectively. The CDE in grade 3 and grade 4 cataracts were 7.8 ± 2.6 and 10.2 ± 3.2 in the high group, respectively, and 7.7 ± 2.2 and 9.9 ± 4.5 in the low group, respectively.
Results suggest that a hybrid phacoemulsification tip was efficient in removing cataracts of grade 3 and grade 4 with high and low IOP settings.
评估一种混合式超声乳化探头在高眼压和低眼压情况下摘除3级和4级白内障的效率。
这是一项随机、前瞻性、双臂对侧眼研究。每个受试者的一只随机眼在高眼压设置（50 mmHg）下进行超声乳化，另一只眼在低眼压设置（20 mmHg）下进行超声乳化。手术终点包括超声乳化时间、抽吸时间、液体用量、累积消散能量（CDE）、总手术时间、总扭转时间和总纵向时间。术后终点包括中央角膜厚度（CCT）和眼压。
共有102只眼（51例患者）完成了研究。3级和4级白内障的超声乳化时间在高眼压组分别为38.4±9.6秒和44.1±9.9秒，在低眼压组分别为38.9±8.6秒和46.3±11.0秒。3级和4级白内障的抽吸时间在高眼压组分别为95.3±21.2秒和111.8±32.8秒，在低眼压组分别为105.4±27.0秒和108.6±23.1秒。3级和4级白内障的液体用量在高眼压组分别为39.2±6.8毫升和45.2±10.8毫升，在低眼压组分别为38.3±7.3毫升和43.2±8.0毫升。3级和4级白内障的CDE在高眼压组分别为7.8±2.6和10.2±3.2，在低眼压组分别为7.7±2.2和9.9±4.5。
结果表明，混合式超声乳化探头在高眼压和低眼压情况下摘除3级和4级白内障是有效的。
