Problems solved by technology

Although various techniques have been employed to help reduce this phenomenon (such as placing the cornea at the edge of the optic that contacts the wall and pressing the IOL against the capsular bag to keep the capsular wall taut), undesired growth of cystic cells remains a problem. Problems to be solved in the field of IOL

Embodiment Construction

[0013] Figure 1A An intraocular lens (IOL) 100 suitable for implantation into a capsular bag of the eye is illustrated in accordance with certain embodiments of the present invention. ( Figure 1B show Figure 1A An enlarged view of the cross-section of the IOL 100 within the dashed box. ) IOL 100 includes an optic 102 , which refers to a central, generally circular body comprising an optical zone configured to focus light on the retina, and a flexible haptic 104 , wherein the optic 102 The haptics 104 are used to position the IOL 100 within the residual portion of the capsular bag after capsulorhexis. Optical component 102 has a front optical face 103 and a rear optical face 105 joined by a peripheral wall 108 . The peripheral wall 108 includes a straight portion 109 of uniform radial width extending rearwardly from the front optical face 103 . The peripheral wall 108 also includes a flared edge 202 that meets the straight portion at a flared point 206 . At flare point 2...

Abstract

An intraocular lens (IOL) for implantation within a capsular bag includes an optic and a plurality of haptics. The optics has an anterior optic face and a posterior optic face joined by a peripheral wall. The peripheral wall includes a straight portion of uniform width extending posteriorly from the anterior optic face to a flare point and a flared optic edge. The flared optic edge extends posteriorly and widens from the flare point and meets the posterior optic face at a sharp optic corner. Each of the haptics is coupled to the optic at the peripheral wall at respective haptic-optic junctions. The flared optic edge surrounds the peripheral wall between the haptic-optic junctions.

Description

[0001] related application [0002] This application claims priority to US Provisional Application Serial No. 61 / 265469, filed December 1, 2009, the contents of which are incorporated herein by reference. technical field [0003] The present invention relates to intraocular lenses (IOLs), and more particularly to an intraocular lens having edges configured to reduce posterior capsule opacification. Background technique [0004] In the simplest terms, the human eye functions to provide vision by transmitting and refracting light through a transparent outer part called the cornea and focusing the image on the retina at the back of the eye by means of a lens. The quality of the image that is in focus depends on many factors, including eye size, shape and length, and the shape and transparency of the cornea and lens. When trauma, age or disease make the lens less transparent, vision declines because less light is transmitted to the retina. This defect in the lens of the eye is...
