Problems solved by technology

However, Nd / YAG laser capsulotomy exposes patients to the risk of serious complications that can lead to significant visual impairment or loss, such as retinal detachment, pupillary obstructive glaucoma, iris hemorrhage, uveal inflammation / vitreitis, and cystoid macular edema
Also, laser energy is typically directed directly through the IOL, which may damage the optics of the implant or disrupt its placement within the capsular bag 108.

Abstract

A capsular ring for insertion into a capsular bag of a patients eye includes an anterior ring defining a first opening and having a first cross-sectional width and a posterior ring defining a second opening and having a second cross-sectional width. A diameter of the first opening is greater than a diameter of the second opening, and the second cross-sectional width is greater that the first cross-sectional width. The capsular ring further includes a sidewall connecting the first ring and the second ring, the sidewall comprising a plurality of orifices spaced circumferentially around the sidewall.

Description

[0001] This application claims priority to US Provisional Application No. 62 / 111723, filed February 4, 2015, which is hereby incorporated by reference in its entirety. technical field [0002] The present disclosure relates generally to cataract surgery, and more particularly to asymmetric capsular rings for inhibiting capsular opacification. Background technique [0003] Cataracts, or clouding of the lens that impair vision, are the leading cause of preventable blindness in the world. Currently, cataracts are treated by surgically removing the affected lens and replacing it with an artificial intraocular lens ("IOL"). figure 1 is a diagram of the eye 100 showing the anatomy involved in the surgical removal of the cataract and the implantation of the IOL. Eye 100 includes a cloudy lens 102 , an optically clear cornea 104 , and an iris 106 . The lens capsule (capsular bag 108 ) located behind the iris 106 of the eye 100 houses the opaque lens 102 . More specifically, the c...
