Abstract: Devices, systems, and methods for treatment of an eye alter aspiration flow from the eye in response to an occlusion of the aspiration conduit pathway. Where aspiration is drawn from the eye using a volumetric pump, the pump can be reversed so as to induce fluid reflux from the aspiration conduit pathway into the eye to help clear the occlusion. The pump may vary the reverse flow in response to sensed aspiration pressure or the like, and the reverse flow may be halted before the pressure within the aspiration conduit pathway adjacent the eye significantly exceeds the irrigation fluid pressure and/or the pressure within the eye. Reflux may alternatively be generated by modulating a vent valve disposed between an irrigation conduit pathway and the aspiration conduit pathway.

Abstract translation: 用于治疗眼睛的装置，系统和方法响应于吸入导管通路的闭塞而改变来自眼睛的抽吸流。 当使用容积泵从眼睛抽取吸液时，泵可以反转，以便将吸入管道通道的流体回流引入眼睛以帮助清除闭塞。 泵可以响应于感测到的吸入压力等而改变反向流动，并且在靠近眼睛的抽吸导管路径内的压力显着超过冲洗流体压力和/或眼睛内的压力之前可以停止反向流动。 可替换地，可以通过调节设置在冲洗导管通道和抽吸导管路径之间的排气阀来产生回流。
