Claims20
An intraocular lens for implanting in a human eye, comprising:
- a) a lens optic having opposite anterior and posterior optic surfaces and an optical axis extending from said anterior surface to said posterior surface;
- b) a posterior concave region located radially outwardly of said posterior optic surface;
- c) an anterior concave region located radially outwardly of said anterior optic surface;
- d) an outer-most peripheral edge surface located radially outwardly of said anterior and posterior concave regions;
- and
- e) a posterior sharp edge disposed between the posterior concave region and at least a portion of the outer-most peripheral edge,
- wherein the lens has a minimum distance between the posterior concave region and the anterior concave region, the minimum distance being less than a second thickness of the lens at a second location that is disposed radially outwardly of the location of the minimum distance.
