A medical device for removing lens tissue from inside a capsular bag of an eye including a cam assembly operatively coupled to a vacuum generation source positioned within the housing. A first portion is operatively coupled to the vacuum generation source and a second portion is operatively coupled to the first portion and to the shaft. The first portion is capable of rotating about an axis to cause the vacuum generation source to generate vacuum through the lumen. The second portion is capable of rotating about the axis with the first portion to cause the shaft to oscillate. A first degree of actuation of a trigger causes the vacuum generation source to generate vacuum within the lumen of the shaft, and a second degree of actuation of the trigger causes the shaft to oscillate as the second portion rotates. Related systems, devices, and methods are provided.
