Simultaneous two-camera video tracings of phacoemulsification surgery and intraocular pressure fluctuations were made. The fluctuations were transmitted to a quartz pressure transducer through a chamber maintainer that was plugged into the anterior chamber. The transducer was connected to a monitor and recorder calibrated to measure pressure variations between -8.6 and +60 mm Hg. Using common audio for synchronization, the pressure tracings were keyed over the surgical videos and combined in a single film. High, medium, and low inflow volume techniques used by many surgeons exhibiting commensurately higher or lower intraocular pressure fluctuations were scrutinized. Methods to increase inflow volume without a proportionate pressure increase were devised.
对白内障超声乳化手术和眼内压波动进行了同步双摄像头视频追踪。波动通过插入前房的房水维持器传递到石英压力传感器。该传感器连接到经过校准的监视器和记录器，以测量-8.6至+60毫米汞柱之间的压力变化。利用普通音频进行同步，将压力追踪结果叠加在手术视频上，并合并到一部影片中。对许多外科医生使用的高、中、低流量技术进行了仔细研究，这些技术呈现出相应较高或较低的眼内压波动。还设计了在不相应增加压力的情况下增加流量的方法。
