: To evaluate the efficiency and safety of high-fluidics ultrasound emulsification using slim-shaft-strong-bevel (SSSB) tip technology for nucleus workup through mini- and micro-incisions. : 77 patients underwent immediate sequential bilateral cataract surgery using high-flow-high-vacuum easyTip2.2 ("eT2.2") or infusion-assisted ("Hybrid") easyTipCOMICS ("eT1.6 iaCOMICS") coaxial phacoemulsification. Surgical time (ST), Effective Phacoemulsification Time (EPT), and fluid consumption (FC), central corneal thickness (CCT), and endothelial cell count (ECC) were recorded. : 50 patients completed the 6 months follow-up. Preoperatively, groups did not differ in nuclear hardness, CCT, or ECC. The median ST for Conquer with eT2.2 phaco was 49 s, with eT1.6 iaCOMICS phaco 57 s ( = 0.021). The median total EPT was 8.3 and 8.0 ( = 0.882), and the median EPT for Conquer was 4.0 and 4.1, respectively ( = 0.812). The median FC for Conquer was 21 mL with the eT2.2 and 22 mL with the eT1.6 iaCOMICS phaco ( = 0.29), and the overall FC was 29 mL and 33 mL, respectively ( = 0.105). Mean CCT was 561 ± 42 µm and 563 ± 45 µm on day 1 ( = 0.835), 539 ± 33 µm and 542 ± 34 µm at 1 week ( = 0.714), and 536 ± 31 µm and 541 ± 33 µm at 6 months ( = 0.55), respectively. Mean ECL at 6 months was 2.80 ± 7.28% and 3.41 ± 8.25% ( = 0.725). : When compared to previously published results obtained with a standard non-waisted phaco needle and lower fluidics and with the waisted easyTip2.2 run with intermediate fluidics, ultrasound-assisted high-fluidics phacoaspiration with the easyTip2.2 through a 2.2 mm incision and the easyTip COMICS through a 1.6 mm incision with infusion-assistance significantly improved efficiency of nucleus workup by reducing ultrasound energy and infusion fluid consumption, with minimal transient corneal stroma swelling and low endothelial cell loss.
评估使用细轴强斜面（SSSB）尖端技术的高流量超声乳化术通过微小切口和微切口进行核处理的效率和安全性。77例患者接受了使用高流量高真空easyTip2.2（“eT2.2”）或输注辅助（“Hybrid”）easyTipCOMICS（“eT1.6 iaCOMICS”）同轴超声乳化术的即时序贯双侧白内障手术。记录手术时间（ST）、有效超声乳化时间（EPT）、液体消耗量（FC）、中央角膜厚度（CCT）和内皮细胞计数（ECC）。50例患者完成了6个月的随访。术前，两组在核硬度、CCT或ECC方面无差异。使用eT2.2超声乳化术进行Conquer的中位ST为49秒，使用eT1.6 iaCOMICS超声乳化术为57秒（P = 0.021）。总中位EPT分别为8.3和8.0（P = 0.882），Conquer的中位EPT分别为4.0和4.1（P = 0.812）。使用eT2.2进行Conquer的中位FC为21 mL，使用eT1.6 iaCOMICS超声乳化术为22 mL（P = 0.29），总体FC分别为29 mL和33 mL（P = 0.105）。第1天的平均CCT分别为561±42 µm和563±45 µm（P = 0.835），1周时为539±33 µm和542±34 µm（P = 0.714），6个月时为536±31 µm和541±33 µm（P = 0.55）。6个月时的平均ECL分别为2.80±7.28%和3.41±8.25%（P = 0.725）。与先前发表的使用标准无腰超声乳化针和较低流量以及使用中等流量的有腰easyTip2.2获得的结果相比，通过2.2 mm切口使用easyTip2.2和通过1.6 mm切口使用带输注辅助的easyTip COMICS进行超声辅助高流量超声乳化吸出术通过减少超声能量和输注液体消耗显著提高了核处理效率，角膜基质短暂肿胀最小且内皮细胞损失低。
