Patent number: 11547554Abstract: A virtual aperture integrated into an intraocular lens is disclosed. Optical rays which intersect the virtual aperture are widely scattered across the retina causing the light to be virtually prevented from reaching detectable levels on the retina. The use of the virtual aperture helps remove monochromatic and chromatic aberrations yielding high-definition retinal images. For a given definition of acceptable vision, the depth of field is increased over a larger diameter optical zone. In addition, thinner intraocular lenses can be produced since the optical zone can have a smaller diameter. This in turn allows smaller corneal incisions and easier implantation surgery.Type: GrantFiled: April 10, 2019Date of Patent: January 10, 2023Assignee: Z Optics, Inc.Inventors: Edwin J. Sarver, James J. Simms

A method for implanting the lens includes the steps of: introducing the first haptic portion with a first anchor portion that includes a plurality of teeth projecting therefrom, into the posterior chamber of the eye until said teeth are anchored in the scleral wall at a desired location; and moving a second haptic portion with a plurality of teeth projecting therefrom, until said teeth are anchored in the scleral wall on the opposite side of the lens from the first anchor portion.Type: ApplicationFiled: June 24, 2011Publication date: February 2, 2012Inventor: JOSHUA BEN NUN

Publication number: 20120016473Abstract: An intraocular lens for implantation in a capsular bag of an eye includes an optic disposed about an optical axis and a haptic including a protruding portion disposed inside the optic. The optic has an anterior face and an opposing posterior face that are configured to provide a lens power. In response to an ocular force of the eye, the haptic transmits a force that alters one or more of a shape of the optic and an axial thickness of the optic. The protruding portion of the haptic has a refractive index that is equal to a refraction index of the optic for at least one a wavelength within the visible spectrum.Type: ApplicationFiled: September 23, 2011Publication date: January 19, 2012Applicant: Abbott Medical Optics Inc.Inventors: Daniel G. Brady, Tuyet Hoc Nguyen, Hendrik A. Weeber, Douglas S. Cali, Timothy R. Bumbalough, Edward P. Geraghty

Patent number: 8034108Abstract: An intraocular lens is disclosed, with an adjustable 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. The haptic may include a cap on the anterior and/or posterior surfaces of the lens. The lens may include a force transfer member, such as a hinge, that couples forces from the haptic to the cap, so that a radial force on the haptic changes the curvature of the cap. The haptic and optic may be refractive index-matched. The cap may be made of the haptic material, which is stiffer than the optic material, and can influence the deformation of the lens during accommodation. A cap on the anterior surface may produce an axial movement of the lens in an anterior direction during accommodation. The cap may also protect the surfaces of the optic during handling and installation.Type: GrantFiled: March 28, 2008Date of Patent: October 11, 2011Assignee: Abbott Medical Optics Inc.Inventor: Timothy R. Bumbalough

Publication number: 20110238174Abstract: An accommodating intraocular lens (AIOL) includes an optic adapted to produce a trapezoidal phase shift and a plurality of haptics. Each haptic extends from a haptic-optic junction to at least one transverse arm contacting a capsular bag of the eye, and each haptic has sufficient length and rigidity to stretch a capsular bag of the eye to contact ciliary muscles of the eye. The haptic-optic junctions vault the optic forward relative to the haptics and compression of the haptics by the ciliary muscles moves the anterior optic forward. A combined accommodative power produced by the motion of the anterior optic and the trapezoidal phase shift is at least 0.5 Diopters.Type: ApplicationFiled: March 8, 2011Publication date: September 29, 2011Inventors: Xin Hong, Mutlu Karakelle, Son Tran, Xiaoxiao Zhang, Myoung-Taek Choi
