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.
Claims20
A modular intraocular lens, comprising:
- a base, comprising:
- an anterior rim having a first opening,
- a posterior rim having a second opening, wherein the posterior rim includes a protruding portion which protrudes radially outwardly from the anterior rim and the posterior rim, and wherein the protruding portion includes at least one corner edge along a posterior perimeter of the posterior rim and at a posteriormost surface of the posterior rim, and
- a recessed groove defining a perimeter of a center hole communicating with the first opening and the second opening, wherein the recessed groove is defined by the anterior rim and the posterior rim;
- and
- a lens comprising an optic and at least one tab portion, wherein the at least one tab portion comprises an actuatable tab;
- wherein the recessed groove of the base is configured to receive the at least one tab portion of the lens.
