20090005866 | FIRST ELASTIC HINGE ACCOMMODATING INTRAOCULAR LENS - An accommodating lens where the optic is moveable relative to the ends of the extended haptic portions. The lens comprises an optic made from a flexible material combined with haptics capable of multiple flexions without breaking. The haptics having in longitudinal cross section wide and deep hinges adjacent the optic to better allow the elastic hinges to “stretch” when the optic is subjected to posterior pressure thus allowing the optic to move forward relative to both the outer and inner ends of the haptics. When this movement is combined with the movement of the optic relative to the outer ends of the haptics and the anterior movement of the whole lens, the refractive power of the eye is further enhanced. | 01-01-2009 |

20110054600 | ACCOMMODATING INTRAOCULAR LENSES - 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. Certain haptic features improve the accommodative performance of the haptic, such that compressive/tensile forces may be more efficiently transferred from the haptic to optic. Furthermore, certain aspects also provide enhanced bag-sizing capability so that the IOL better fits within the capsular bag. | 03-03-2011 |
20110054601 | FIXATION OF OPTHALMIC IMPLANTS - An accommodating intraocular lens (aIOL) is disclosed, with an optic that changes shape in response to an ocular 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. A surface adherent improves the accommodative performance of the haptic, such that compressive/tensile forces may be more efficiently transferred from the haptic to optic. One way to enhance force transfer is to provide a surface layer of an adhesive to the haptic and/or optic, for instance a reversible bioadhesive material. Or, portions of the exterior surface of the IOL may have microfibers thereon that mimic the adhesive properties of Gecko feet. Another aspect is application of a reversible bioadhesive material to the interior of the empty capsular bag prior to introduction of an injectable polymer IOL. | 03-03-2011 |

The support may be adjustable, such that patient refraction and accommodation can be adjusted following surgery. The support may comprise rigidity sufficient to decrease radial movement of the intermediate portion of the lens capsule. The support can be placed on the intermediate portion to decrease radial movement of the intermediate portion of the lens capsule and increase radial stretching of an outer portion of the lens capsule extending between the zonules and the intermediate portion coupled to the support, such that the amount of accommodation of the eye is increased. The support may comprise a biocompatible material capable of stable coupling to the lens capsule following implantation, such that the far vision refraction and accommodation of the eye can be stable following surgery. | 03-08-2012 |
20120078364 | ACCOMMODATING INTRAOCULAR LENS - An Accommodating Intraocular Lens (AIOL) is disclosed herein, that is comprised of a flexible optic and a flexible haptic rim that conforms to the human eye capsule. The spherical or custom shape of the optic is engineered to be maintained during accommodation through the mechanical/optic design of the implant and the interaction between the implant and the naturally occurring position and actuating forces applied through ciliary muscles/zonules/and capsule as the brain senses the need to increase the diopter change or magnification when an object of fixation approaches the eye. The axial relocation or position of the AIOL may also be further adjusted anatomically to further improve the affect needed to achieve improved accommodation. Optionally, the Accommodating Intraocular Lens (AIOL) is foldable or injectable for delivery of the lens into the eye. | 03-29-2012 |
20120290086 | INTRAOCULAR CAPSULAR TENSION RINGS - Arcuate arms each approximately semi-circular extend generally oppositely from a central fixation element. Together the arms and integral fixation element form a capsular tension ring to apply outward pressure along the equator of an ocular lens capsule during surgery. The ring can be loaded into an insertion tube by pulling on the central fixation element such that the arms are drawn into the tube together. Similarly, the arms are expelled together from the tube during insertion into the capsule so as to equalize the force applied to the capsule during insertion of the ring. | 11-15-2012 |
