20080269889 | Haptic Junction Designs to Reduce Negative Dysphotopsia - 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 have a portion that redirects light that is incident thereon in a manner which alleviates or prevents dysphotopsia. For example, the light that is incident on a fixation member can be directed to a retinal location intermediate to where imaging typically occurs on the retina and where a secondary image is formed. Various techniques for achieving these improvements are discussed, both in terms of the structures of improved IOLs, and methods for alleviating dysphotopsia. | 10-30-2008 |
20080269890 | INTRAOCULAR LENS WITH PERIPHERAL REGION DESIGNED TO REDUCE NEGATIVE DYSPHOTOPSIA - In one aspect, the invention provides an intraocular lens (IOL) that includes an optic and a peripheral optical flange that surrounds the optic. The optic can form an image of a field of view on the IOL user's retina and the peripheral flange can inhibit dysphotopsia. By way of example, the peripheral flange can include at least one textured surface that is adapted to receive peripheral light rays entering the eye at large visual angles so as to cause their scattering in order to inhibit dysphotopsia, e.g., by preventing the formation of a secondary peripheral image or scattering some light to a shadow region between such a secondary image and an image formed by the IOL. | 10-30-2008 |
20080269891 | INTRAOCULAR LENS WITH EDGE MODIFICATION - Intraocular lenses (IOLs) with modified edge characteristics are disclosed to inhibit transverse propagation of internally reflected light rays in order to alleviate, and preferably eliminate, dysphotopsia and/or the perception of dark shadows reported by some users. In one embodiment, IOL designs are disclosed that incorporate an opaque edge or other mechanisms for capturing internally reflected peripheral light rays. In other embodiments, the peripheral region can include a light scattering material or can have a disproportional thickness or be contoured to redirect peripheral rays. | 10-30-2008 |

20140200666 | Adjustable Toric Intraocular Lens - An adjustable astigmatism-reducing intraocular lens includes a toric optic with a long axis. The optic is rotationally coupled to haptics, and a plurality of struts extend between the optic and the haptics. The struts are held under tension and individually releasable via laser, or are heat shrinkable to increase the tension of selective struts. When a strut is released or shrunk, a torsional force is applied to angularly adjust the optic relative to the haptics. After the lens has been implanted and healed relative to the tissue, struts are individually released via laser ablation to cause torsional instability and resulting net rotational adjustment, or individually heat shrunk to tension the strut, to cause torsional instability, and effect net rotational adjustment to ensure that a long axis of optic is aligned with the axis of astigmatic correction of the eye. | 07-17-2014 |
