    Abstract: A haptic is provided for use in an accommodating intraocular lens. The haptic has multiple filaments, each connected to the edge of the optic at one end. Each filament has a shape that conforms to an equatorial region of the capsular bag. The haptic couples the forces exerted by the capsular bag of the eye during accommodation radially to the edge of the optic, produce a diametric expansion or compression of the optic. This diametric motion distorts the optic, producing a change in any or all of the anterior radius, the posterior radius, and the thickness. These changes affect the power of the lens and/or location of the image. The haptic may optionally have a thin membrane joining the filaments at the optic end, and may optionally have a connecting ring that joins the filaments at the end opposite that of the optic.

  • Publication number: 20100131061
    Abstract: The inventive is directed to a haptic for fixation to, and manufacture in conjunction with, an intraocular lens to be implanted in the natural lens capsule of the human eye. The haptic secures the lens in an appropriate position within the natural capsule so as to provide optimal visual acuity through the aphakic lens. The haptic ends are designed to position the lens neutrally, anteriorly or posteriorly within the lens envelope. At the connection point of the ribbon portion to the solid end plate of the haptic, the haptic may be notched to facilitate compressing the lens into its injector for insertion into the eye through an incision in the cornea. Once compressed and passed through the cornea, the implanted lens will be secured by the haptics in the lens capsule once all possible natural lens material and epithelial cells have been removed.

The fixation member includes an intermediate portion that extends a first direction away from the optic, and a leg portion that intersects with an outer end of the intermediate portion and extends a second direction, different from the first direction, away from the outer end. The leg portion preferably includes a reduced width region near the intersection with the intermediate portion. 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.

  • Publication number: 20040034417
    Abstract: A foldable lens having a plurality of generally “T”-shaped haptics that vault the lens posteriorly when implanted in the eye while still providing stable fixation of the lens within the eye. Such a construction ensures firm contact between the optic and the posterior capsule while still allowing the anterior capsule and the posterior capsule to contact and cause fibrosis about the haptics.

  • Patent number: 6660035
    Abstract: 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 and a suspension structure. The movement members are coupled to a periphery of the optic. The suspension structure is coupled to the movement members and is adapted to be in contact with a peripheral region of a capsular bag of an eye. The movement members are adapted to convert radial movement of the suspension structure caused by movement of the capsular bag to axial movement of the optic. The movement members are also adapted to amplify the radial movement of the suspension structure so that the optic moves axially a greater distance than the distance moved radially by the suspension structure.

  • Publication number: 20030204253
    Abstract: A posterior chamber phakic lens made from an elastomeric, foldable, highly biocompatible material. The lens has a generally circular optic and a pair of integrally formed haptics. The haptics project posteriorly from the optic. A plurality of holes or slots are formed along the edge of the optic and along the length of the haptics. A soft, highly biocompatible material may be placed into the holes or slots by a friction fit or a primary/secondary molding process. Such a construction helps to avoid pupillary blockage, allows for improved aqueous flow around the natural lens and provides a spacer to hold the lens away from the anterior capsular and the iris.

  • Publication number: 20030181977
    Abstract: An intraocular lens having an ultrathin and highly pliable optic and relatively more rigid fixation members extending outward therefrom. The optic desirably includes a flange to which a common arm of a pair of joined fixation members attaches. The fixation members extend on opposite sides of the optic in U-shaped flex portions spanning a distance larger than the diameter of the optic. 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. The fixation members have a thickness of about 0.25 mm and are desirably made of poly methyl methacrylate (PMMA) or polyether sulfone.

  • Patent number: 6616693
    Abstract: An intraocular lens having an optic and a plurality of fixation members coupled to the optic. The fixation members are adapted to flex about points located closer to the outer edge of the IOL than to the optic. The fixation members may have a converging width intermediate region projecting outward from the optic and a pair of leg portions extending generally perpendicularly thereto. The leg portions include foot members and flex radially inward with respect to the intermediate region. Because the optic and intermediate regions are relatively stable, the leg portions flex inward but the optic does not vault or bow upon a compressive fit within the surrounding eye.
