主权项

1. An intraocular lens implant for implantation within a capsular bag formed with a capsulorrhexis defining a capsulorrhexis edge, comprising:
a lens having a convex anterior optical portion including a first convex portion and a second portion, and a posterior optical portion, the convex anterior optical portion and the posterior optical portion being located on opposite anterior and posterior sides, respectively, of a single circumferential edge of the lens, with the circumferential edge being positioned at and forming a single maximum diameter of the lens, the circumferential edge being defined by a single annular wall having an axial length and extending between an anterior edge and a posterior edge, with the anterior edge and the posterior edge being spaced apart by the length; an annular groove formed in the convex anterior optical portion between the first convex portion and the second portion and being defined by an anterior wall and a posterior wall, with the second portion extending radially inwardly from the anterior edge of the annular wall and the entire annular groove being positioned anteriorly of the annular wall and extending from a surface of the convex anterior optical portion and being configured to receive the capsulorrhexis edge, and a haptic member extending outwardly from the circumferential edge.
