Publication number: 20040199149Abstract: Methods for the creation of microspheres treat the clear, intact crystalline lens of the eye with energy pulses, such as from lasers, for the purpose of correcting presbyopia, other refractive errors, and for the retardation and prevention of cataracts. Microsphere formation in non-contiguous patterns or in contiguous volumes works to change the flexure, mass, or shape of the crystalline lens in order to maintain or reestablish the focus of light passing through the ocular lens onto the macular area, and to maintain or reestablish fluid transport within the ocular lens.Type: ApplicationFiled: January 2, 2004Publication date: October 7, 2004Inventors: Raymond I.

Publication number: 20040148023Abstract: A high gain lens system for implant into the capsular bag after removal of the natural crystalline lens. A preferred embodiment of the invention comprises a combination of a positive or convex lens and a negative or concave lens. These two lenses are spaced from one another and their relative spacing and respective focal lengths determine their combined focal length. When the lens system is inserted into the capsular bag, two opposed haptic flanges on each side, extend toward the inner radial edge of the bag adjacent the ciliary muscles. When the muscles contract, the bag is stretched thereby compressing the haptic flanges together or at least toward one another. This action cause the two lenses to separate further from each other and the increased spacing between the positive and negative lenses shortens the focal length to permit focusing of objects at near distances. On the other hand, when the muscles relax, the bag relaxes also, the haptic flanges separate and the lenses come closer together.Type: ApplicationFiled: January 15, 2004Publication date: July 29, 2004Inventor: Stephen K. Shu

Patent number: 6702853Abstract: A system and method for removing cataract cells inside of a lens capsule of an eye and inserting into the lens capsule an intraocular lens having an adhesive applied to at least one of its surface. Preferably, the adhesive is applied to the surface of the intraocular lens that faces the cornea of the eye. The adhesive causes the lens to adhere to an interior portion of the lens capsule, such as the remaining epithelial layer. The lens capsule conforms or shrinks around the intraocular lens, removing substantially any space between the lens capsule and the intraocular lens. Since there is no room between the lens capsule and the intraocular lens, proliferation of the remaining cells will not occur and therefore capsular opacification is eliminated or substantially reduced. Additionally, since the lens capsule and the intraocular lens are coupled together, the intraocular lens can move when ciliary body muscles contract and therefore, the focal point of the eye can change as in a normal eye.Type: GrantFiled: October 2, 2000Date of Patent: March 9, 2004Inventor: Gholam A.

Publication number: 20040039446Abstract: An intraocular lens (IOL) has been provided with an accommodation assembly that effects axial movement of the IOL optic through both the radial action of ciliary muscles and the axial forces resulting from vitreous pressure on the posterior wall of the capsular bag. In a preferred embodiment, the assembly comprises an IOL having substantially rigid, posteriorly extending fixation members which extend through slots in an accommodation ring encircling the optic. Axial forces exerted by vitreous fluids on the posterior wall of the capsular bag are transmitted from the posterior wall to the ring to the fixation members at the slot areas, causing axial movement of the IOL. At the same time, the angulation of the haptics converts radial forces due to contraction or expansion of the capsular bag into axial forces, causing still more axial movement of the IOL.Type: ApplicationFiled: August 26, 2002Publication date: February 26, 2004Applicant: Advanced Medical Optics, Inc.Inventor: Thomas McNicholas

Patent number: 6645245Abstract: Disclosed is an implant for implantation in the human eye, which enables natural adjustment of the eye to different distances (accommodation) after cataract surgery (lens opacity). Permanent magnets (inner magnets) rest on the periphery of the intraocular lens located inside the capsular sack. Two additional permanent magnets that are fixed to the sclera (outer magnets) are located opposite to said inner magnets and slightly staggered to the back. The inner and outer magnets are polarized and geometrically disposed in such a way that they repel one another. Said repulsion effects a forward movement of the capsular sack and the lens located therein when the ciliary muscle contracts. Before placing the outer magnets, a measurement can be conducted with the aid of electromagnets whose strength can be regulated, whereby accommodation is determined as a function of the strength of the outer magnets.Type: GrantFiled: June 29, 2001Date of Patent: November 11, 2003Inventor: Paul Rolf Preussner

Patent number: 6592621Abstract: A flexible biconvex lens for intra-capsular implantation in an intra-ocular lens capsule of a patient enables the lens refractive properties to be to altered by the transfer of forces from ciliary muscles of the patient to said the flexible biconvex lens. The flexible lens comprises a plurality of holes spaced at equal radial intervals around the periphery of the lens. The plurality of holes promote tissue ingrowths to secure the flexible biconvex lens to the intra-ocular lens capsule without requiring peripheral mechanical extensions, adhesives or mechanical fasteners to said flexible biconvex lens.Type: GrantFiled: November 10, 2000Date of Patent: July 15, 2003Inventor: Rudolph S. Domino

Publication number: 20030109926Abstract: An accommodating intraocular lens is disclosed that provides vision accommodation in response to contraction of an eye's ciliary muscle. The intraocular lens comprises a deformable elastic dynamic lens having a non-accommodating surface curvature and a lens-shaping member having flexible portions in contact with peripheral edge regions of the dynamic lens for enabling compressive deformation thereof for changing the lens surface curvature to achieve accommodation. Included are an elastically flexible coil member mounted around the lens-shaping member flexible portions. A first lens-supporting member has a proximal end region that engages the flexible coil member and a second lens-supporting member has a proximal end region connected to the lens-shaping member.Type: ApplicationFiled: December 10, 2001Publication date: June 12, 2003Inventor: Valdemar Portney

Publication number: 20030109925Abstract: An intraocular lens includes an optic for focusing light and a movement assembly coupled to the optic. The movement assembly is adapted to cooperate with the eye to effect accommodating movement of the optic. The movement assembly includes a plurality of movement members each with a proximal region coupled to the optic and an enlarged distal region. The enlarged distal region may be integral with the proximal region, or may be mechanically coupled thereto.Type: ApplicationFiled: December 23, 2002Publication date: June 12, 2003Applicant: Allergan Sales, Inc.Inventors: Massoud Ghazizadeh, Joseph I.

Publication number: 20030105522Abstract: This intraocular lens includes an optic body having anterior and posterior walls, a chamber, and optically transmissive primary and secondary fluids. The secondary fluid is substantially immiscible with the primary fluid and has a different density and a different refractive index than the primary fluid. The primary fluid is present in a sufficient amount that orienting optical body optical axis horizontally for far vision positions the optical axis through the primary fluid, thereby immersing the anterior and posterior optical centers in the primary fluid. The secondary fluid is contained in the optic body in a sufficient amount that orienting the optical axis at a range of effective downward angles relative to the horizontal for near vision positions the optical axis to extend through the primary fluid and the secondary fluid, thus changing the focus of the intraocular lens.Type: ApplicationFiled: May 3, 2002Publication date: June 5, 2003Inventor: Alan N.
