To evaluate the clinical outcomes of new phacoemulsification technology.
Oregon Eye Institute, Eugene, Oregon, USA.
After optimization of surgical parameters, patients were randomly assigned to cataract extraction with 1 of 4 phacoemulsification machines using new technology available within the past 1 to 2 years. Outcomes were compared with previously published results for these same machines obtained before the advent of the new technology.
Improvements in effective phaco time, average phaco power, percentage of clear corneas, and 20/40 or better uncorrected visual acuity at the first postoperative visit were noted for most systems using new technology.
New phacoemulsification technology offers surgical advantages that translate into improved clinical outcomes.
评估新型超声乳化技术的临床效果。
美国俄勒冈州尤金市的俄勒冈眼科研究所。
在优化手术参数后，患者被随机分配使用过去1至2年内可用的新技术，通过4台超声乳化机器中的1台进行白内障摘除术。将结果与这些相同机器在新技术出现之前获得的先前发表的结果进行比较。
大多数使用新技术的系统在有效超声乳化时间、平均超声乳化功率、透明角膜百分比以及术后首次就诊时20/40或更好的未矫正视力方面都有改善。
新型超声乳化技术具有手术优势，可转化为更好的临床效果。
