  • Patent number: 9339375
    Abstract: Disclosed herein is an implantable capsule expander device for insertion within a lens capsule of an eye of a patient. The device comprises an arcuate center portion including first and second rims and having a first height, an outermost peripheral portion including a second height that is less than the first height, and a receiving portion formed between the first and second rims. The center portion and the outermost peripheral portion are configured to stabilize the capsule expander device within the lens capsule and to expand the lens capsule. The receiving portion is sized to receive an artificial intraocular lens.

  • Patent number: 9072600
    Abstract: A curvature changing accommodative intraocular lens for implantation into the eye of a patient includes a lens body having a base lens which has a base lens power, and a haptic structure including haptic elements projecting from the base lens. An actuator is placed into engagement with the lens body, and includes actuator haptic elements. At least one fluidic optical element is received between the actuator and base lens of the lens body and contains a fluid material therein. During accommodation of the patient's eye, the haptic elements of the lens body and actuator are engaged and apply a force to the fluidic optical element, causing the fluidic optical element to be deformed to generate an additional lens power to adjust the patient's vision.

    Abstract: A two part lens system. The first part is a ring-like supporting component that is implanted in the capsular bag following cataract surgery. The first component is a non-optical component and contains a pair of haptics for fixating the first component within the capsular bag. The second component is an optical component that contains all of the corrective optical power of the lens system. The second component has a pair of tabs for locking the second component within the first component.

  • 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: 20090204209
    Abstract: A two-optic accommodative lens system. The first lens has a negative power and is located posteriorly within the capsular bag and lying against the posterior capsule. The periphery of the first lens is attached to a ring-like structure having sloping sides. The second lens is located anteriorly to the first lens within of the capsular bag and is of a positive power. The peripheral edge of the second lens contains a plurality of haptics that project posteriorly from the second lens and toward the first lens. The haptics are relatively firm, yet still flexible and ride within the sloping sides of the ring-like structure, so that flattening or steepening of the capsule in reaction to movement of the ciliary muscle and corresponding shrinkage of the capsular bag causes the second lens to move along the optical axis of the lens system.

  • Publication number: 20080269881
    Abstract: Asymmetric intraocular lenses (IOLs) are disclosed in which the centration of the optic and the pupil can be adjusted in order to reduce dsyphotopsia and/or the perception of dark shadows. For example, IOLs with uneven haptics are disclosed such that the center of the optic (i.e., the optical axis) is offset from a centerline of the overall device.

  • Patent number: 7300464
    Abstract: A two or three component lens system. The first component is a ring-like supporting component that is implanted in the capsular bag following cataract surgery. The first component is a non-optical component and does not correct for any refractive errors. The first component may contains features to help reduce or eliminate PCO. The second component is an optical component that may contain all of the corrective optical power of the lens system. The second component has a pair of tabs for locking the second component within the first component. The third component is optional and is similar to second component and contains some optical power to correct for any residual optical error not corrected by the second component. The second and third components may also be implanted so as to move relative to one another, thereby providing some accommodation.

  • Publication number: 20040249455
    Abstract: A two-optic accommodative lens system. The first lens has a negative power and is located posteriorly within the capsular bag and lying against the posterior capsule. The periphery of the first optic contains a plurality of generally T-shaped haptics. The overall diameter of the first optic is slightly smaller than the capsular bag. The second optic is located anteriorly to the first optic outside of the capsular bag and is of a positive power. The peripheral edge of the second optic contains a plurality of generally T-shaped haptics and the second optic is slightly larger in overall diameter that the first optic. The haptics allow the second optic to move relative to the first optic along the optical axis of the lens system in reaction to movement of the ciliary muscle and corresponding shrinkage of the capsular bag.

  • Patent number: 6616691
    Abstract: A two-optic accommodative lens system. The first lens has a negative power and is located posteriorly within the capsular bag and laying against the posterior capsule. The periphery of the first optic contains a pair of generally T-shaped haptics having a generally rectangular slot within the top portion of the “T”. The second optic is located anteriorly to the first optic outside of the capsular bag and is of a positive power. The peripheral edge of the second optic contains a pair of encircling haptics having a notched tab sized and shape to fit within the slots in the haptics on the first optic to lock the second optic onto the first optic. Hinge structures on the encircling haptics allow the second optic to move relative to the first optic along the optical axis of the lens system in reaction to movement of the ciliary muscle.

  • Publication number: 20030097177
    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, plate-style haptics. The haptics project posteriorly from the optic. A plurality of openings are formed at the intersection of the optic and the haptics, the holes extending all the way through the lens. The distal tips of the haptics are split or forked so as to project anteriorly and posteriorly. The anterior arm is designed to fit against the posterior iris, and the posterior arm is design to be supported in the anterior ciliary sulcus. Such a construction 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.

  • Patent number: 6562070
    Abstract: An anterior chamber phakic lens made from an elastomeric, foldable, highly biocompatible material. The lens has a generally circular optic and integrally formed plate-style haptics, the haptics containing an opening into which project a pair of pincer arms. the pincer arms are sized and shaped so as to pull away from each other when the lens is folded, and are draw back toward each other when the folded lens is released and allowed to return to its unfolded state. Such movement allows the pincers to gather a small section of the iris so as to hold the lens in place.
