Embodiment Construction

[0022] Referring to the drawings, the cross-sectional view in FIG. 1 shows that the human eye 10 has an anterior chamber 12 and a posterior chamber 14 separated by an iris 30 . The capsule 16 within the posterior chamber 14 holds the natural lens 17 of the eye. Light entering the eye passes through the cornea 18 to the lens 17 which directs and focuses the light onto the retina 20 at the back of the eye. The retina is connected to the optic nerve 22, which transmits the images received by the retina to the brain to render the image.

[0023] In an eye where the natural lens is damaged (eg, blurred by cataract), the natural lens is no longer able to properly focus and direct incoming light rays to the retina, and images become blurred. One well-known technique to remedy this condition involves removing the damaged lens and possibly replacing it with an artificial lens, known as an intraocular lens or IOL, such as prior art IOL 24 shown in FIG. 2 . While there are many differe...

Abstract

An intraocular lens for inhibiting posterior and anterior capsular opacification, or secondary cataract, includes an optic having a periphery provided with sharp bevels extending along arc segments defined by the juncture of the haptic-optic points of attachment and adjacent both the anterior and posterior optic surfaces.

Description

technical field [0001] The present invention relates to intraocular lenses (IOLs) suitable for implantation in aphakic eyes following removal of the natural lens due to injury or disease (eg, a cataract lens). In particular, the present invention relates to a novel IOL designed to inhibit the undesirable growth of lens epithelial cells (LECs) located between the IOL and the capsular bag and on the optical surface of the IOL. Background technique [0002] When cell growth occurs along the posterior capsule wall, it is referred to by those skilled in the art as posterior capsule opacification, or "PCO." When cell growth occurs along the wall of the anterior capsule, it is referred to by those of skill in the art as anterior capsule opacification, or "ACO." [0003] One well-known and ideal way to manage a cataract eye is to remove the cloudy natural lens and replace it with an artificial IOL in a surgical procedure called cataract extraction. In extracapsular extraction meth...
