OCULAR IMPLANT TO CORRECT DYSPHOTOPSIA, GLARE, HALOS AND DARK SHADOW TYPE PHENOMENA
First Claim
1. An intraocular lens (IOL), comprising:
- an optic for implantation in a subject'"'"'s eye; and
at least one fixation member coupled to said optic for anchoring said optic in the subject'"'"'s eye, said at least one fixation member adapted to position said optic sufficiently close to the iris to inhibit dysphotopsia.

Abstract
Methods and devices for inhibiting the dark shadow effect, known as dysphotopsia, perceived by some subjects having implanted intraocular lenses (IOLs) are presented. In one aspect, an IOL can include an optic and one or more fixation members for facilitating placement of the IOL. The fixation member can be adapted to position the optic sufficiently close to the iris to inhibit dysphotopsia. As some examples, a fixation member can position an optic to within some distance of the tip of the iris, or the fixation member can be adapted to contact a portion of an eye posterior to an optic'"'"'s posterior surface; or the fixation member can have an end that is posterior to a posterior surface of the optic. Various techniques for achieving these improvements among others are discussed, both in terms of the structures of improved IOLs, and methods for alleviating dysphotopsia.
