Abstract
An ophthalmic surgical instrument includes a housing and a snare operably coupled to the housing. The snare is configured to transition between an insertion configuration and a deployed configuration, in which the snare is sized to encircle lenticular tissue. The ophthalmic surgical instrument is designed to prevent elevation and/or tilting of the lenticular tissue as the snare transitions toward the insertion configuration to divide the lenticular tissue.

An ophthalmic surgical instrument, comprising:
- a housing;
- a snare operably coupled to the housing and configured to transition between an insertion configuration and a deployed configuration, in which the snare is sized to encircle lenticular tissue;
- and
- a pair of arms operably coupled to the housing and disposed on opposite sides of the snare, wherein the pair of arms are configured to move between a closed configuration and an open configuration, in which the pair of arms flare outwardly relative to a longitudinal axis defined by the snare.

An ophthalmic surgical instrument for severing a cataractous lens, comprising:
- a housing;
- a snare operably coupled to the housing and including a looped segment configured to move between a contracted configuration and a dilated configuration, in which the looped segment assumes a diameter approximating a diameter of a cataractous lens, wherein the looped segment is configured to sever the cataractous lens upon moving toward the contracted configuration;
- and
- a pair of arms operably coupled to the housing and disposed on opposite sides of the looped segment of the snare, wherein the pair of arms are configured to move between a collapsed configuration and an expanded configuration, in which the pair of arms extend outwardly relative to the looped segment of the snare.
