  • Patent number: 10285806
    Abstract: A multifocal ophthalmic lens includes an ophthalmic lens and a diffractive element. The ophthalmic lens has a base curvature corresponding to a base power. The diffractive element produces constructive interference in at least four consecutive diffractive orders corresponding a range of vision between near and distance vision. The constructive interference produces a near focus, a distance focus corresponding to the base power of the ophthalmic lens, and an intermediate focus between the near focus and the distance focus.

  • Patent number: 10028823
    Abstract: An intraocular lens includes a lens capsule expanding device and an optical portion. The lens capsule expanding device includes a front supporting portion to make contact with an inner surface of an anterior capsule. A rear supporting portion provided on a rear side of the front supporting portion makes contact with an inner surface of a posterior capsule while facing the front supporting portion. A connecting portion connects the front supporting portion and the rear supporting portion so as to have biasing force in a direction of separating the front supporting portion and the rear supporting portion from each other. Due to the biasing force, the front supporting portion presses the inner surface of the anterior capsule and the rear supporting portion presses the inner surface of the posterior capsule. The optical portion changes the curvature of a central portion according to movement of the connecting portion.

Appropriate inhibitor compounds include RGD mimetics, RGD peptides, and flavonoids. A second method involves surface modifying the exterior surface of a capsular tension ring by covalently attaching a mitotic inhibitor, preferably a conjugate of methotrexate and a bovine serum albumin, and implanting this inhibitor tension ring into the capsular bag of an eye of a patient during extracapsular cataract surgery.

The optic (32, 94a, 94b, 142, 216) of the present invention possess greater refractive capability than optics conventionally used in IOL construction, and permits retinal receipt of the image being viewed in order to correct refractive errors.

  • Patent number: 7871437
    Abstract: An intraocular lens for providing accommodative vision to a subject includes a frame disposed about an optical axis, a first optical element, a second optical element, and a connecting element operably coupling the frame to the optical elements. The frame comprises an anterior frame element and a posterior frame element. The connecting element is configured to convert a first displacement between the frame elements in a direction that is substantially parallel to the optical axis into a second displacement between the optical elements that is substantially perpendicular to the optical axis. The second displacement may be translational and/or rotation. In some embodiments, the optical elements are two varifocal lenses.

  • Publication number: 20100262234
    Abstract: A posterior chamber phakic lens made from an elastomeric, foldable, highly biocompatible and permeable material. The lens has a generally circular optic and a plurality of integrally formed, filament-like haptics. The haptics project posteriorly from the optic and contain a raised feature or ridge that is sandwiched between the posterior iris and the zonules when implanted in an eye. Such a construction has a low vaulting force under compression, is size insensitive, provides for a stable lens once implanted in the eye, helps to avoid pupillary blockage and allows for improved aqueous flow around the natural lens.

  • Publication number: 20100211169
    Abstract: Intraocular lenses (IOLs) and related methods. One embodiment provides an IOL which includes a lens optic and a pair of haptics. The haptics can be coupled to the lens optic and can cause compression of the lens optic when the IOL is fixated in an eye. The lens optic can have a compressed geometry, an uncompressed geometry including an aberration, and a desired geometry. The compressed geometry can be the desired geometry. The aberration can be astigmatism, coma, or spherical aberration. For instance, the aberration can be astigmatism of about 0.17 D at the spectacle plane and of about 0.25 D at the intraocular lens plane. Moreover, the haptics can define a first axis between the haptics; the lens optic can define a second axis perpendicular to the first axis; and the uncompressed geometry can differ from the compressed geometry in the vicinity of the second axis.

  • Publication number: 20100094412
    Abstract: An improved multifocal design for an ocular implant is provided. This ocular implant can include an accommodating intraocular lens (IOL) and a number of haptics. The accommodating IOL includes a liquid suspended between two optically transparent plates or membranes to form a pressure lens that passes optical energy. The haptics mechanically couple to the IOL in order to position and secure the IOL within the eye. The IOL achieves accommodation by using the eye's ciliary muscles to vary the surface curvature of the liquid. The liquid may have a high surface tension and be surrounded by phobic liquid. Pressure from the ciliary muscles causes fluid to be added from or withdrawn to a reservoir. Increasing/decreasing the internal pressure of the liquid changes the angle (curvature) of the surface thus changing the optical properties of the lens. When the pressure is released the liquid returns to the reservoir. The whole system may be sealed off from the interior of the eye by a membrane/transparent lens.
