| 20080269881 | Intraocular Lens with Asymmetric Haptics - Asymmetric intraocular lenses (IOLs) are disclosed in which the centration of the optic and the pupil can be adjusted in order to reduce dsyphotopsia and/or the perception of dark shadows. For example, IOLs with uneven haptics are disclosed such that the center of the optic (i.e., the optical axis) is offset from a centerline of the overall device. | 10-30-2008 |
| 20080269882 | INTRAOCULAR LENS WITH ASYMMETRIC OPTICS - In one aspect, an intraocular lens (IOL) is discloses that includes an optic having a central portion and a peripheral extension that partially surrounds the central portion. Once implanted in a patient's eye, the IOL's optic forms an image of a field of view with the peripheral extension inhibiting dysphotopsia. While in some embodiments, the peripheral extension provides focusing of light incident thereon, in other embodiments, it can include at least one textured surface for scattering the light or at least one opaque surface for preventing the light from reaching the retina. In other embodiments, the peripheral extension can include one or more translucent surface(s) for diffusing the light passing therethrough to inhibit dysphotopsia. | 10-30-2008 |
| 20080269883 | OCULAR IMPLANT TO CORRECT DYSPHOTOPSIA, GLARE, HALOS AND DARK SHADOW TYPE PHENOMENA - Methods and devices for inhibiting the dark shadow effect, known as dysphotopsia, perceived by some subjects having implanted intraocular lenses (IOLs) are presented.

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.

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. | 10-30-2008 |
