1. A surgical device for cutting a lens within a capsular bag of an eye, the device comprising:
- a shaft extending from a housing along a longitudinal axis of the device, the shaft having a lumen and a distal end;
a cutting element movable through the lumen of the shaft, the cutting element comprising;
a first sectioning element; and
a second sectioning element,wherein each of the first and second sectioning elements has a first end, a second end, and a distal loop formed between the first and second ends; and
an actuator operatively coupled to the cutting element,wherein the cutting element is configured to transition from a first, retracted configuration towards a second, expanded configuration upon a first activation of the actuator, andwherein, when in the second, expanded configuration, the distal loop of each of the first and second sectioning element defines an enlarged open area located outside the distal end of the shaft, the enlarged open area having a first leg advanced distally relative to the distal end of the shaft and a second leg positioned proximally to the distal end of the shaft.

31. A surgical device for cutting a lens within a capsular bag of an eye, the device comprising:
-
a shaft extending from a housing along a longitudinal axis of the device, the shaft having a lumen and a distal end; a cutting element movable through the lumen of the shaft, the cutting element comprising at least a first sectioning element having a first end, a second end, and a distal loop formed between the first and second ends; a slider operatively coupled to the cutting element and movable along the longitudinal axis of the housing; and a stroke counting mechanism coupled to the slider and contained within the housing, wherein the cutting element is configured to transition from a first, retracted configuration towards a second, expanded configuration upon distal extension of the slider, and wherein, when in the second, expanded configuration, the distal loop of the at least a first sectioning element defines an enlarged open area located outside the distal end of the shaft, the enlarged open area having a first leg advanced distally relative to the distal end of the shaft and a second leg positioned proximally to the distal end of the shaft, and wherein the stroke counting mechanism is configured to track distal extensions and/or proximal extensions of the slider. - View Dependent Claims (32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44)
