Problems solved by technology

For example, dehiscence or rupture of some of the zonules may cause an uneven zonular tension and decentration of the lens.
However, passing a suture through the residual capsular bag jeopardizes the residual capsular bag's integrity and therefore jeopardizes long-term IOL centration and stabilization.

Embodiment Construction

[0018] Reference is now made to FIG. 1, which illustrates an intraocular clip 10, constructed and operative in accordance with an embodiment of the present invention.

[0019] The intraocular clip 10 may include first and second hook members 12 and 14 extending in opposite directions from a spine 16. The first and second hook members 12 may be generally coplanar with spine 16. In the illustrated non-limiting embodiment, spine 16 is common to, that is, shared by both hook members 12 and 14. A curved crook 18 may be formed between each of hook members 12 and 14 and one end 20 of spine 16. Each of the hook members 12 and 14 may include arms 22 spaced from spine 16 on opposite sides of spine 16. In the illustrated non-limiting embodiment, the arms 22 are generally parallel to spine 16.

[0020] The intraocular clip 10 may be constructed of a biologically compatible material, such as but not limited to, polymethylmethacrylate (PMMA), silicone, silicone rubber, collagen, hydrogel, hyaluronic ...

Abstract

An intraocular clip including first and second hook members extending generally coplanarly in opposite directions from a spine, the spine being formed with an attachment member attachable to ocular structure.

Description

FIELD OF THE INVENTION [0001] The present invention relates generally to eye implants for human eyes and, more particularly, to an intraocular clip that may be used to affix the capsular bag to adjoining ocular tissue. BACKGROUND OF THE INVENTION [0002] As is well known in the art of cataract surgery, a continuous curvilinear capsulorhexis is performed on the anterior capsule to remove the natural lens. The anterior capsule has a generally smooth surface contour except at the equator, where the zonules attach. In such a case, the IOL generally remains well centered postoperatively after the continuous curvilinear capsulorhexis. However, in certain cases, the capsular bag may become decentered. For example, dehiscence or rupture of some of the zonules may cause an uneven zonular tension and decentration of the lens. If an artificial lens is situated within a capsular bag with partial zonular support, the IOL optic edge or elements of the haptic may be situated in the visual axis lead...
