We described a one-handed rotational phacoemulsification technique to decrease phaco time and power, and surgical stress on the cornea in eyes with different types of cataract.
In this technique a single sutureless corneal incision was made without any side-port incision. After hydrodissection and hydrodelamination were performed, a phaco tip was positioned in contact with the nucleus beside the capsulorhexis edge. By using a peristaltic pump, phacoemulsification was started with high levels of vacuum to keep the probe tip on the edge of the lens and to ensure the rotation of the nucleus, and with low ultrasound energy. The torsional mode used required less occlusion time and volume of fluid. The inclination of the tip was modified to 45-degree, directing it toward the lens center. So the nucleus was aspirated from the periphery toward the center by a rotational movement.
The eye in the technical video had a NC4-NO4 cataract. The preoperative vision in this eye was 20/100 with no improvement with refraction. On postoperative day 1, visual acuity had improved to 20/20. We recorded low intraoperative parameters including ultrasound time (21.4 sec), phacoemulsification power (73%), balanced salt solution used (31 mL) and cumulative dissipated energy (7.27) at the conclusion of the case. After 1 month, Central Corneal Thickness changed from 504 µm to 516 µm, and Endothelial Cell Loss was 1.15%.
This technique uses a single clear corneal incision, high vacuum and low ultrasound power to reduce the exposition to excessive surgical maneuvers, fluid turbulence and ultrasound energy.
我们描述了一种单手旋转超声乳化技术，以减少不同类型白内障患者的超声乳化时间和能量，以及对角膜的手术压力。
在该技术中，制作单一的无缝合角膜切口，不做任何侧切口。在进行水分离和水分层后，将超声乳化头置于撕囊边缘旁与核接触。通过蠕动泵，以高真空水平启动超声乳化，使探头尖端保持在晶状体边缘以确保核的旋转，并使用低超声能量。所使用的扭转模式所需的阻塞时间和液体量较少。将探头尖端的倾斜度调整为45度，使其朝向晶状体中心。因此，通过旋转运动将核从周边吸向中心。
技术视频中的眼睛患有NC4-NO4白内障。该眼术前视力为20/100，矫正后无改善。术后第1天，视力提高到20/20。在手术结束时，我们记录了较低的术中参数，包括超声时间（21.4秒）、超声乳化能量（73%）、使用的平衡盐溶液量（31毫升）和累积消散能量（7.27）。1个月后，中央角膜厚度从504微米变为516微米，内皮细胞损失率为1.15%。
该技术采用单一透明角膜切口、高真空和低超声功率，以减少过度的手术操作、液体湍流和超声能量暴露。
