Abstract
An accommodating intraocular lens device is provided. The accommodating intraocular lens device comprises a base assembly and a power lens. The base assembly comprises a first open end, a second end coupled to a base lens, and a haptic surrounding a central cavity. The haptic may comprise an outer periphery, an inner surface and a height between a first edge and a second edge. The power lens is configured to fit within the central cavity. The power lens may comprise a first side, a second side, a peripheral edge coupling the first and second sides, and a closed cavity configured to house a fluid. The first side of the power lens may be positioned at a predetermined distance from the first edge of the haptic.
Claims49
An accommodating intraocular lens device comprising:
- a haptic component comprising an outer portion and an inner portion spaced inward relative to the outer portion, the outer portion configured to engage a capsular bag, and the inner portion extending radially inward, the haptic component having an asymmetric profile in cross-section about an anterior-posterior axis disposed through an anterior-most portion of the haptic component, wherein the asymmetric profile comprises a radially inward protrusion of the inner portion;
- and
- a power lens comprising a flexible membrane on one side, an optic on an opposing side, a circumferential peripheral edge coupling the flexible membrane and the optic, and an inner reservoir disposed between the flexible membrane, the optic, and the circumferential peripheral edge, wherein the circumferential peripheral edge comprises a radially outwardly facing depression, the depression configured to receive the radially inward protrusion of the inner portion of the haptic component to restrict anterior-posterior relative movement of one of the power lens and the haptic component relative to the other of the power lens and the haptic component.
An accommodating intraocular lens device comprising:
- a haptic system comprising an outer portion, an inner portion, and a closed space defined between the outer and the inner portions, wherein the closed space comprises an outer reservoir configured to contain a fluid and wherein the inner portion circumscribes at least a portion of a central space;
- and
- a power lens comprising a flexible membrane having a first side disposed on one outer side of the accommodating intraocular lens device, an optic having a first side disposed on an opposing outer side of the accommodating intraocular lens device, an uninterrupted fluid reservoir extending from a second side of the flexible membrane to a second side of the optic, and a circumferential peripheral edge coupling the flexible membrane and the optic;
- wherein the power lens is configured to be disposed within the central space such that at least a portion of the circumferential peripheral edge is in facing relation to the inner portion of the haptic system.
An accommodating intraocular lens device comprising:
- a base comprising an outer portion, an inner portion, and a closed space defined between the outer and the inner portions, wherein the closed space comprises a first reservoir configured to contain a fluid;
- and
- a power lens comprising a flexible membrane on one side, an optic on an opposing side, a circumferential peripheral edge coupling the flexible membrane and the optic, and a second reservoir disposed between the flexible membrane, the optic, and the circumferential peripheral edge, wherein the circumferential peripheral edge comprises an outer surface and an inner surface disposed radially inward relative to the outer surface, the outer surface and the inner surface cooperating to receive the inner portion of the base against the inner surface of the power lens after insertion of the power lens into an eye to restrict anterior-posterior relative movement of at least one of the power lens and the base relative to the other of the power lens and the base;
- wherein a posterior side of the optic faces an interior surface of a capsular bag when the accommodating intraocular lens device is implanted in the eye such that light passing through the posterior side does not pass through another component of the accommodating intraocular lens device in traversing the eye to a retina thereof;
- and
- wherein the second reservoir is in fluid communication with the first reservoir of the base to cause the fluid in the first reservoir to flow into the second reservoir to apply or to enhance application of fluid pressure directly to a surface of the flexible membrane.
