  • Publication number: 20100004742
    Abstract: An accommodating intraocular lens having anteriorly and posteriorly movable extended portions, such as T-shaped haptics, extending from a central optic to be implanted within a human eye, and a second optic spaced from the posterior optic. The first optic is intended to be implanted in the capsular bag, and the second optic may be located in the capsular bag, in the sulcus, or in the anterior chamber. The second optic can be spaced from and fixed to the first optic and this lens assembly implanted in the capsular bag.

  • Patent number: 7510578
    Abstract: Intraocular lenses for implanting within the natural capsular bag of the human eye having features on the outer ends or portions of the lenses to fixate the lens within the natural capsular bag following implantation.

  • Publication number: 20090005866
    Abstract: 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.

  • Publication number: 20080294254
    Abstract: An accommodating intraocular lens where the optic is moveable relative to the outer ends of the extended portions. The lens comprises an optic made from a flexible material combined with extended portions that are capable of multiple flexions without breaking. The optic has a blended central area of increased power of 1 diopter or less to give the patient a single focal point on wavefront examination after implantation into the eye increasing the depth of focus to aid near vision.

  • Publication number: 20080288066
    Abstract: There is disclosed herein a “piggyback” cylindrical (toric) intraocular lens for placement in front of an accommodating or standard intraocular lens that is already in the capsular bag of the eye. This additional lens is placed in the sulcus, which leaves a significant space between the two lenses, particularly if the lens in the capsular bag is vaulted backwards.
