Abstract
An ocular clip implant (22) used for securing an intraocular lens (IOL) (62) in an eye of a patient is provided which includes an IOL-engaging portion (26) disposed at a first end of the ocular clip implant (22). The IOL-engaging portion (26) is configured to grasp a portion of the IOL (62). An ocular-wall-engaging portion (28) is integrated with and disposed at a second end of the ocular clip implant (22). The ocular-wall-engaging portion (28) includes an anchor (29) transitionable from a first, straightened configuration to a second, non-straightened configuration to anchor the ocular clip implant (22) to a wall of the eye in order to secure the IOL (62) to the eye. Other embodiments are also described.
Claims15
An ocular clip implant used for securing an intraocular lens (IOL) in an eye of a patient, the ocular clip implant comprising:
- an IOL-engaging portion disposed at a first end of the ocular clip implant, the IOL-engaging portion:
- being configured to grasp a portion of the IOL, and
- comprising first and second opposing jaws which are moveable with respect to each other to grasp the portion of the IOL, the first jaw being positionable against a first surface of the portion of the IOL at a first location to apply pressure to the first surface of the portion of the IOL, and the second jaw being positionable against a second surface of the portion of the IOL at the first location to apply pressure to the second surface of the portion of the IOL;
- and
- an ocular-wall-engaging portion integrated with and disposed at a second end of the ocular clip implant, the ocular-wall-engaging portion comprising an anchor transitionable from a first, straightened configuration to a second, non-straightened configuration to anchor the ocular clip implant to a wall of the eye in order to secure the IOL to the eye.
An ocular clip implant used for securing an intraocular lens (IOL) in an eye of a patient, the ocular clip implant comprising:
- an IOL-engaging portion disposed at a first end of the ocular clip implant, the IOL-engaging portion being configured to grasp a portion of the IOL;
- and
- an ocular-wall-engaging portion integrated with and disposed at a second end of the ocular clip implant, the ocular-wall-engaging portion comprising an anchor, the anchor:
- being reversibly transitionable from a first, straightened configuration to a second, non-straightened configuration to anchor the ocular clip implant to a wall of the eye in order to secure the IOL to the eye,
- comprising a shape-memory material which transitions the anchor of the ocular-wall-engaging portion from the first, straightened configuration to the second, non-straightened configuration, and
- being deformable from the second, non-straightened configuration upon application of a force to the ocular-wall-engaging portion,
- wherein the ocular-wall-engaging portion is shaped so as to define an opening for reversible coupling of a suture to the ocular-wall-engaging portion, and wherein application of a pulling force to the suture facilitates application of the force to the ocular-wall-engaging portion to deform the anchor of the ocular-wall-engaging portion from the second configuration.
A method for securing an intraocular lens (IOL) in an eye of a patient, the method comprising:
- introducing within the eye through an entry point in the eye an IOL-engaging portion of an ocular clip implant, the IOL-engaging portion disposed at a first end of the ocular clip implant;
- grasping a portion of the IOL with the IOL-engaging portion by moving first and second opposing jaws of the IOL-engaging portion with respect to each other, and by the moving:
- positioning the first jaw against a first surface of the portion of the IOL at a first location;
- positioning the second jaw against a second surface of the portion of the IOL at the first location;
- and
- applying pressure to the first and the second surfaces of the portion of the IOL by the first and the second jaws, respectively;
- securing the IOL to the eye by anchoring the ocular clip implant to a wall of the eye by:
- positioning an ocular-wall-engaging portion integrated with and disposed at a second end of the ocular clip implant, partially within the wall of the eye and through the entry point and partially proximally to the wall of the eye;
- and
- facilitating transitioning of an anchor of the ocular-wall-engaging portion from a first, straightened configuration to a second, non-straightened configuration.
