目的在体外实验中，应用Sovereign®超声乳化仪和WhiteStar系统(Allergan)，结合Olson灌注刀(ASICO)和19号裸超声乳化针，分别在100%功率、100%功率和100%功率下，对2只人身体眼进行超声乳化术。在整个实验过程中都对温度数据进行了监测。结果在100%连续超声乳化功率下，吸入线完全闭塞时，温度不超过27.3°C，当100%连续功率时，吸入线完全闭塞时，温度不超过32.5°C。第一只眼和第二只眼的伤口温度分别在45秒和29秒内发生变化。结论在使用Sovereign超声乳化仪和WhiteStar系统的情况下，使用裸19号吸引针的两刺入双眼显微超声乳化术，在最高能量设置下不能产生伤口烧伤，除非所有进入眼睛的血流和所有的吸入物都被阻断。这些设置远远超出了临床适用的条件，并提供了使用WhiteStar系统可以安全地进行微超声乳化手术的证据。
PurposeTo verify the temperature-induction effect of bimanual ultrasound-based phacoemulsification through 2 stab incisions with a bare aspiration needle and new proprietary technology.SettingIn vitro laboratory.MethodsThe Sovereign® phacoemulsification unit and the WhiteStar system (Allergan) were used in conjunction with the Olson irrigating chopper (ASICO) and a 19-gauge bare phaco needle in 2 human cadaver eye-bank eyes at 100% power unoccluded, 100% power with aspiration completely occluded, and 100% power with aspiration and flow completely occluded. Temperature data were monitored throughout the experiment. Any sign of a wound burn, defined as temperature exceeding 45°C, whitening around the wound, or wound contraction, was the end point.ResultsAt 100% continuous phacoemulsification power, the temperature did not rise above 27.3°C. When the aspiration line was totally occluded at 100% continuous power, the temperature did not rise above 32.5°C. When flow into the eye and aspiration were completely occluded at 100% power, a wound change and temperature of 45°C occurred in 45 seconds in the first eye and in 29 seconds in the second eye.ConclusionsUsing the Sovereign phacoemulsification unit with the WhiteStar system during 2-stab-incision bimanual microphacoemulsification with a bare 19-gauge aspiration needle in human cadaver eyes, a wound burn could not be produced at the highest energy settings unless all flow into the eye and all aspiration were occluded. These settings were well beyond clinically applicable conditions and provide evidence that microphacoemulsification can be performed safely with the WhiteStar system.
