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.
Claims20
An ophthalmic surgical instrument for severing a lens of an eye, comprising:
- an elongated shaft including:
- a proximal end portion;
- and
- a distal end portion defining an opening, the distal end portion being offset from the proximal end portion;
- and
- a snare extending along the elongated shaft and including a cutting segment disposed adjacent the opening and configured to move between a contracted configuration and a dilated configuration, in which the cutting segment assumes a diameter approximating a diameter and shape of a lens, wherein the cutting segment is configured to sever the lens upon moving toward the contracted configuration.

An ophthalmic surgical instrument for severing a lens of an eye, comprising:
- a handle;
- an elongated shaft extending distally from the handle and including a distal end portion defining an opening, the distal end portion being angled relative to a proximal portion of the elongated shaft that is disposed proximally of the distal end portion;
- and
- 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 and shape of a lens, wherein the looped segment is configured to sever the lens upon moving toward the contracted configuration.
