And it provides an apparatus, a system and method for rapidly venting the vacuum so as to reduce the occlusion break surge inside the lens hydrodynamic intake system. The suction system generates a flow by utilizing a positive displacement pump, by utilizing the vent valve, the pressure or vacuum level in the eye, and based on the pressure sensor feedback detected by the pump can be controlled or vented. In the embodiments described herein, the various rotation (angular rotation) when a quick-vent valve is provided with an open-fast to create an open flow reaction. These rapid-flow performance in the open vent valve is improved by increasing the effective area of the closing of the valve close-up position. In particular, by complementary to the circular edge of the passage opening formed through a vent valve forming a concave edge to achieve increased cross-sectional area.
