20110313519 | Accommodating Intraocular Lens - An intraocular lens for insertion into a capsular bag of an eye comprises: an optic; and at least one plate haptic coupled to the optic by one or more flexible connecting members. The plate haptic with flexible finger extensions is designed to engage the periphery of the capsular bag. An increase in radial pressure upon constriction of the ciliary muscle causes the rigid posteriorly vaulted plate haptics to move centrally to further increase the vitreous cavity pressure with constriction of the ciliary muscle: the optic with its thin stretchable hinge across the connecting member is then displaced anteriorly along the axis of the eye. The haptic includes a longitudinally rigid frame to restrict deformation of the haptic in a longitudinal direction while permitting deformation in a transverse direction. Furthermore, the flexible connecting members include one or more hinged straps that extend radially and/or longitudinally from the optic. The optic can move forwards and backwards, relative to both the distal and proximal ends of the plate haptics, in response to ciliary muscle contraction and relaxation with an increase and decrease of vitreous cavity pressure. Finger-like projection extends from the plate haptic to engage the capsular bag to center and fixate the accommodating lens within the capsular bag. | 12-22-2011 |
20110313524 | Vitreous Compressing Plate Haptic - A plate haptic is used with an intraocular lens optic displaceable in response to vitreous pressure changes. The plate haptic comprises: a plurality of opposing lateral portions; a distal portion having a plurality of opposing projections extending substantially laterally therefrom; and a proximal portion comprising a strap across which is a hinge connecting the lens optic to the haptic. The intersection of the proximal portion with each lateral portion forms a plurality of appendages, or paddles, to partially surround the optic. The appendages, projections, and hinged straps combine to substantially aid displacement of the lens optic in response to changes in vitreous pressure. | 12-22-2011 |
20110313525 | Tilt Stabilizing Accommodating Intraocular Lens - An intraocular lens for insertion into a capsular bag of an eye. A plurality of flexible connecting members couples a lens optic to a pair of opposing of plate haptics. The coupling members stabilize the optic with respect to the haptics. The coupling members are spaced apart straps having grooves that increase lens response to changes in vitreous pressure. | 12-22-2011 |
20110313526 | Semi-Rigid Framework For A Plate Haptic Accommodating Intraocular Lens - A plate haptic for an accommodating intraocular lens. The plate haptic has a haptic body that is substantially rigid in a longitudinal direction and substantially flexible in a transverse direction. A chassis is integral to the haptic body. The chassis causes the haptic body to be substantially more rigid in a longitudinal direction than in a transverse direction. | 12-22-2011 |
20120296425 | Variable Focus Intraocular Lens - A variable focus intraocular lens comprises an optic coupled to at least one haptic at a flexion that sets a non-zero angle between the optic and the haptic. | 11-22-2012 |
20120310344 | Biased accommodating intraocular lens - An accommodating intraocular lens has a lens optic that is coupled to at least one haptic and is anteriorly biased with respect thereto. | 12-06-2012 |
20140088699 | TORSION BAR ACCOMMODATING INTRAOCULAR LENS - An accommodating intraocular lens comprising a lens optic coupled to at least one haptic and a torsion bar positioned between the lens optic and the at least one haptic such that the torsion bar facilitates accommodation by deforming in response to a vitreous pressure change. | 03-27-2014 |
20140094909 | ACCOMMODATING INTRAOCULAR LENS - An accommodating intraocular lens comprising a lens optic coupled to at least one haptic and at least one deformable connecting bar positioned between the lens optic and the at least one haptic such that the connecting bar facilitates accommodation by deforming in response to a vitreous pressure change. | 04-03-2014 |
20140155871 | METHOD FOR PREPARING CORNEAL DONOR TISSUE FOR REFRACTIVE EYE SURGERY UTILIZING THE FEMTOSECOND LASER - A method of accurately fabricating a non-human donor corneal tissue for implantation into a recipient human cornea, the method comprising the steps of: removing corneal tissue from a donor with a femtosecond laser; placing the corneal tissue in a fixative solution for a selected time interval to cross-link the collagen fibrils in the tissue and prevent swelling of the corneal tissue; and shaping the tissue to provide a conical inlay of a selected shape and thickness having one or more radial extensions. The method is such that the corneal inlay may be attached to the peripheral corneal and/or the sclera. The method is such that the corneal inlay may be stored for a period of up to two years prior to attachment. | 06-05-2014 |
20140172093 | INTRAOCULAR LENS - A variable focus intraocular lens comprises an optic coupled to at least one haptic at a rigid flexion that sets a non-zero angle between the optic and the haptic. | 06-19-2014 |
20150012088 | SEMI-RIGID FRAMEWORK FOR A PLATE HAPTIC ACCOMMODATING INTRAOCULAR LENS - A plate haptic for an accommodating intraocular lens. The plate haptic has a haptic body that is substantially rigid in a longitudinal direction and substantially flexible in a transverse direction. A chassis is integral to the haptic body. The chassis causes the haptic body to be substantially more rigid in a longitudinal direction than in a transverse direction. | 01-08-2015 |
20150073550 | BIASED ACCOMMODATING INTRAOCULAR LENS - An accommodating intraocular lens has a lens optic that is coupled to at least one haptic and is anteriorly biased with respect thereto. | 03-12-2015 |
20150088254 | ANTERIOR CAPSULE DEFLECTOR RIDGE - An accommodating intraocular lens designed to provide a space in front of the lens optic, to allow it to move forward with accommodation, by stretching its connections to opposing plate haptics, to provide the patient with seamless vision from distance to near. The lens is designed to separate and prevent fibrosis of the anterior capsular rim with the posterior capsule where it surrounds the optic. | 03-26-2015 |
