  • Patent number: 10052194
    Abstract: An intraocular lens is disclosed, with an 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. Certain haptic features improve the accommodative performance of the haptic, such that compressive/tensile forces may be more efficiently transferred from the haptic to optic. Furthermore, certain aspects also provide enhanced bag-sizing capability so that the IOL better fits within the capsular bag.

  • Patent number: 9333072
    Abstract: An intraocular lens includes a plurality of lenses with a rear lens portion disposed in a posterior capsule from which an eye lens is extracted and a front lens portion disposed at the front side inside the eye in relation to the rear lens portion, and a support portion of the front lens portion among the lenses has flexibility. Accordingly, when the inside of the user's eye moves, the support portion is bent, and hence the front lens portion moves. When the front lens portion moves so that the gap between the front lens portion and the rear lens portion changes, a focal distance of a lens system including the front lens portion and the rear lens portion changes. Accordingly, it is possible to realize an intraocular lens capable of changing a focal distance in a manner such that a user moves the inside of an eye.

    Abstract: An accommodating intraocular lens to be implanted within the natural capsular bag of a human eye from which the natural lens matrix has been removed through an anterior capsule opening in the bag circumferentially surrounded by an anterior capsular remnant. During a postoperative healing period following surgery, the anterior capsular remnant fuses to the posterior capsule of the bag by fibrosis about haptics on the implanted lens while the ciliary muscle is maintained in its relaxed state by a cycloplegic to prevent dislocation of the lens, and the lens is deflected rearwardly by the fibrosing anterior capsular remnant to a distant vision position against the elastic posterior capsule of the bag in which the posterior capsule is stretched rearwardly.

  • Patent number: 6461384
    Abstract: An intraocular lens including an optic portion having an outer peripheral edge and two, three or four balanced looped haptic elements for use to achieve refractive correction. Each looped haptic is formed to have greater resistance to bending in a plane generally parallel to an eye's optical axis than in a plane generally perpendicular to the eye's optical axis. The intraocular lens is designed with specific flexibility characteristics so as to exhibit less than approximately 1.0 mm axial displacement of the optic portion along the eye's optical axis under a compression force suitable to effect a 1.0 mm in diameter compression of the intraocular lens.

  • Patent number: 6200344
    Abstract: A refractive intraocular lens including an optic portion having an outer peripheral edge and two or more but preferably two balanced opposed looped haptic elements. Each looped haptic element is formed to have two broad connecting portions, two radial orientation portions, two spring portions and a linking portion for supporting the optic portion in a patient's eye. The two broad connecting portions of each looped haptic element is permanently connected to the outer peripheral edge of the optic portion. Each looped haptic element is likewise formed to have greater resistance to bending in a plane generally parallel to an eye's optical axis than in a plane generally perpendicular to the eye's optical axis. The intraocular lens is so designed to exhibit less than approximately 1.0 mm axial displacement or tilting of the optic portion along the eye's optical axis under a compression force suitable to effect a 1.0 mm in diameter compression in overall length of the intraocular lens.
