Abstract: 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.

Abstract: 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.

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 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.

Abstract: An intraocular lens is disclosed, with an optic that changes shape in response to a deforming force exerted by the zonules of the eye. A haptic supports the optic around its equator and couples the optic to the capsular bag of the eye. The haptic may be pre-stressed before the optic is placed within it. After such placement, the pre-stress may be relieved, and the haptic may produce stress in the optic. The pre-stress may produce a radial tension or a radial compression in the optic. Alternatively, once the optic is placed within the haptic, both may undergo a process that changes the size and/or shape of one with respect to the other, causing a stress within the optic. This process may produce a radial tension or a radial compression in the optic. The haptic may include an annular ring having outer and inner diameters that may depend on the stiffness of the haptic.

The reduced width region acts essentially as a hinge allowing the leg portion to flex about the intermediate portion in responsive to compressive forces, while the intermediate portion and optic remain stable.

Abstract: An adjustable lens system. In a first embodiment, the lens system of the present invention is a two optic system. The optics are connected by an expandable material that allows the distance between the optics to increased in-situ. In a second embodiment of the present invention is a single optic system having a section made from an expandable material at or near the junction between the optic and the centering haptics. Expansion of these section causes the haptics to move radially away from the optic. Such movement may allow for recentering of the lens or, if the haptics are slightly vaulted, radial movement of the haptics away from the optic will cause axial movement of the lens system along the visual axis.

The fixation members may be flexed inward so as to overlap within the diameter of the optic and define an insertion profile of less than about 5 mm. For anterior implantation, four relatively evenly circumferentially spaced pods are provided by the pair of fixation members. The optic center desirably has a thickness of less than about 0.5 mm for meniscus type optics, and may be made of silicone, hydrophilic acrylic, or hydrophobic acrylic.

Abstract: An intraocular lens (IOL) system includes an optic, a pair of haptics located on sides of the optic, and hinge portions at each of the optic haptic junctions. The hinge portions have stressed and non-stressed configurations. One or more restraining elements are provided to maintain the stressed state configuration of the hinge portion during implantation and during a post-operative period during which the capsular bag of the eye heals about the lens. The restraining elements are thereafter removable, preferably via a non-surgically invasive manner, e.g., via dissolution or laser light. Removal of the restraining elements allows anteriorization of the optic as the lens assumes a non-stressed configuration during accommodation. The ciliary body and lens may then interact in a manner substantially similar to the physiological interaction between the ciliary body and a healthy natural crystalline lens.

Abstract: A lens, having an optical power surface, which may have multiple radii portions or aspherical portions as well as spherical portions, is molded in a coined old. A pair of core pins, positioned within the mold cavity during the lens forming process, will produce a pair of haptic-mounting holes within the lens. As the lenses are subsequently tumbled to remove flash, indentations will form adjacent to the haptic-mounting holes. These indentations allow for tangential attachment of the haptic to the lens which, in turn, enables maximum flexibility without exceeding the width of the optic.
