Abstract
An accommodation-facilitating intraocular implant has: a ring sized to fit within a capsular lens bag of an eye; and a plurality of haptics angularly spaced around and radially extended from the ring. A multi-curve implantable accommodating intraocular lens has a convex anterior and concave posterior.
Claims16
An accommodation-facilitating intraocular implant comprising:
- a ring sized to fit within a capsular lens bag of an eye;
- and
- a plurality of haptics angularly spaced around and radially extended from the ring;
- in which each haptic:
- has a tongue that forms an arcuate sulcus gripping part that, in use within the capsular lens bag, inserts into and follows a circumferential groove of the sulcus to restrict circumferential sliding of the tongue around the sulcus;
- and
- is structured to move, under contraction and expansion of the ciliary muscles of the eye, to adjust the ring along an optical axis of the eye;
- in which the ring is made of rigid or resilient material, and the haptics and ring are structured, by having the haptics extended from one of opposed annular faces of the ring, to bias in use the ring to press against an implantable accommodating intraocular lens (IOL), located posteriorly of the ring within the capsular bag of an eye, to one or both deform or move the IOL in a posterior direction, under contraction of the ciliary muscles of the eye, to a greater extent than if the accommodation-facilitating intraocular implant was not present, to increase a dioptric power of the IOL to a sufficient extent such that the near-sighted viewing of a nearby focal point using the IOL is improved by the contact pressure of the ring against the IOL.

An accommodating intraocular lens (IOL) assembly comprising:
- an implantable accommodating intraocular lens (IOL) within a capsular bag of an eye, the implantable accommodating IOL having an optic lens and a plurality of IOL haptics angularly spaced around and radially extended from the optic lens;
- and
- an accommodation-facilitating intraocular implant comprising a ring fitted within the capsular lens bag of an eye, anterior to and in contact with the optic lens;
- in which the ring is made of rigid or resilient material, and the ring is biased, by having the haptics extended from one of opposed annular faces of the ring, to press against the optic lens, located posteriorly of the ring within the capsular bag of an eye, to one or both deform or move the optic lens in a posterior direction, under contraction of the ciliary muscles of the eye, to a greater extent than if the accommodation-facilitating intraocular implant was not present, to increase a dioptric power of the optic lens to a sufficient extent such that the near-sighted viewing of a nearby focal point using the IOL is improved by the contact pressure of the ring against the IOL.

A method comprising:
- inserting an accommodation-facilitating intraocular implant into a capsular lens bag of an eye, into contact with and anterior to an intraocular lens (IOL) that is also within the capsular lens bag, in which the accommodation-facilitating intraocular implant is inserted through an incision in an anterior portion of the capsular lens bag, to position the accommodation-facilitating intraocular implant such that:
- a plurality of haptics of the accommodation-facilitating intraocular implant are inserted into and follow a circumferential groove of the sulcus to grip the sulcus;
- under contraction and expansion of ciliary muscles of the eye, the plurality of haptics move to adjust the ring along an optical axis of the eye to adjust a dioptric power of the IOL to accommodate a focal power of the eye;
- and
- the ring is made of rigid or resilient material, and the haptics and ring bias, by having the haptics extended from one of opposed annular faces of the ring, the ring to press against the IOL, to one or both deform or move the IOL in a posterior direction, under contraction of the ciliary muscles of the eye, to a greater extent than if the accommodation-facilitating intraocular implant was not present, to increase a dioptric power of the IOL to a sufficient extent such that the near-sighted viewing of a nearby focal point using the IOL is improved by the contact pressure of the ring against the IOL.
