GRADUATED BLUE FILTERING INTRAOCULAR LENS
First Claim
1. An intraocular lens (IOL) comprising:
- an optic for implantation in a subject'"'"'s eye;
the optic exhibiting non-uniform light transmissivity over at least a portion of the optic so as to inhibit perception of visual artifacts in a peripheral visual field of the subject'"'"'s eye.

Abstract
Devices and methods utilizing novel intraocular lens (IOL) designs are discussed herein. One aspect relates to IOLs having an optic with non-uniform light transmissivity. For example, the optic of the IOL can include a central region having a reduced light transmissivity relative to another portion of the optic. In addition, or alternatively, the optic can have a peripheral region having reduced light transmissivity. Such IOLs can potentially be utilized to alter the light distribution impinging on a subject'"'"'s retina, which can be tailored to specific lighting situations such as bright and dim light conditions. Such IOLs can also, or alternatively, be used to help alleviate the perception of dark shadows known as negative dysphotopsia. Other aspects and features of IOLs, and methods, are also discussed.

26. An intraocular lens comprising:
an optic for implantation in a subject'"'"'s eye, the optic exhibiting non-uniform light transmissivity such that light transmissivity in an inner region of the optic is less than light transmissivity in an intermediate region of the optic, and light transmissivity in an outer region of the optic is less than light transmissivity in the intermediate region. - View Dependent Claims (27, 28, 29, 30, 31)

32. An intraocular lens (IOL), comprising
an optic disposed about an optical axis, the optic exhibiting light transmissivity that is symmetric about the optical axis and radially non-uniform relative to the optical axis, the radial non-uniformity being adapted to inhibit perception of peripheral visual artifacts.

40. A method for inhibiting dysphotopsia in a patient having an implanted intraocular lens (IOL), comprising:
directing peripheral light rays intercepted by the IOL such as to inhibit perception of visual artifacts in a peripheral visual field of an eye of the patient, the IOL having non-uniform light transmissivity. - View Dependent Claims (41, 42, 43)
