Abstract
Modular IOL removal systems and methods that cut an optic portion of an intraocular in a single motion such to facilitate removal of the optic portion from an eye through an incision, for example a corneal incision, without increasing the size of the corneal incision. Various cutting tools having one or more blades may be utilized. The cut intraocular lens may have one continuous cut or be cut into multiple smaller pieces. The single cutting step may apply balanced forces and torque to avoid damaging the surrounding eye anatomy, reducing the risk of trauma.
Claims38
A device configured for insertion into a capsular bag of an eye, the device comprising:
- an annular anterior portion comprising a first rim surrounding a first opening, the first rim having a first radially inner portion, wherein the first radially inner portion includes at least one notch therein;
- an annular posterior portion comprising a second rim surrounding a second opening, the second rim having a second radially inner portion, wherein the second radially inner portion includes at least one cutout therein;
- an annular intermediate portion extending between the annular anterior portion and the annular posterior portion, wherein the annular intermediate portion protrudes radially outwardly from the annular anterior portion and the annular posterior portion, and wherein the annular intermediate portion has an exterior that includes an anterior facing surface and a posterior facing surface;
- and
- a passage extending through the annular anterior portion, the annular intermediate portion, and the annular posterior portion.
A device configured for insertion into a capsular bag of an eye, the device comprising:
- an anterior portion, wherein the anterior portion comprises:
- a first rim having a first radially inner portion, wherein the first radially inner portion includes at least one notch therein, and
- a first opening, wherein the first rim surrounds the first opening;
- a posterior portion, wherein the posterior portion comprises:
- a second rim having a second radially inner portion, wherein the second radially inner portion includes at least one cutout therein, and
- a second opening, wherein the second rim surrounds the second opening;
- an intermediate portion extending between the anterior portion and the posterior portion, wherein the intermediate portion protrudes radially outwardly from the anterior portion and the posterior portion;
- and
- a passage extending through the anterior portion, the intermediate portion, and the posterior portion, wherein the passage extends between the first opening and the second opening.
A device configured for insertion into a capsular bag of an eye, the device comprising:
- an anterior portion having a first opening therein, a first rim surrounding the first opening, and the first rim having at least one notch therein;
- a posterior portion having a second opening therein, a second rim surrounding the second opening, and the second rim having at least one cutout therein, wherein centers of the at least one notch and the at least one cutout are radially aligned;
- an intermediate portion extending between the anterior portion and the posterior portion, wherein the intermediate portion comprises a third sidewall, wherein the third sidewall has a third radially outward facing surface, and wherein the third radially outward facing surface is radially outward of the first radially outward facing surface and the second radially outward facing surface;
- and
- a passage extending through the anterior portion, the intermediate portion, and the posterior portion, wherein the passage extends between the first opening and the second opening.
