1. An ophthalmic surgical device for cutting a lens while the lens is contained within a capsular bag of a human eye, the device comprising:
an elongate shaft defining a longitudinal axis, the elongate shaft comprising a lumen, an opening from the lumen, and a distal-most end, wherein the opening extends through a side wall of the elongate shaft near the distal-most end; and
a sectioning element operably coupled to the elongate shaft and comprising a looped segment configured to transition between a collapsed, insertion configuration and a fully expanded, capture configuration,
wherein transition of the looped segment from the collapsed, insertion configuration towards the fully expanded, capture configuration causes the looped segment to exit the lumen through the opening and causes a proximal portion of the looped segment to move proximally relative to the opening and a distal portion of the looped segment to move distally relative to the opening, and
wherein, when the looped segment is in the fully expanded, capture configuration, the looped segment defines, in part, an open area sized and shaped to receive the lens of the human eye, the proximal portion of the looped segment overlapping a first portion of the side wall that is located proximal to the opening and the distal portion of the looped segment overlapping a second portion of the side wall that is located distal to the opening and is located distal to the distal-most end of the elongate shaft,
wherein transitioning the looped segment from the fully expanded, capture configuration towards the collapsed, insertion configuration is configured to cut the lens positioned within the open area.
