Disclosed is an accommodating intraocular lens device for treatment of an eye including a stabilization haptic (120) configured to be positioned within a region of an eye and a lens body having a sealed chamber containing a fixed volume of optical fluid. The lens body includes a shape changing membrane (145) configured to outwardly bow in a region surrounding the optical axis of the eye; a shape deformation membrane configured to undergo displacement relative to the first shape changing membrane; and a static element (150). An inner surface of the shape changing membrane, an inner surface of the shape deformation membrane and an inner surface of the static element collectively form the sealed chamber. The lens device also includes a force translation arm (115) having a first end configured to contact an outer surface of the shape deformation membrane of the lens body and a second end configured to engage a ciliary structure of the eye. The force translation arm is configured to move relative to the lens body upon movement of the ciliary structure.

A method of implanting an intraocular optic assembly that has at least a first and second optics interconnected to one another with a plurality of stanchions can include rotating the first optic and the second optic relative to one another and thereby drawing the stanchions at least one of between the first optic and the second optic and around one of the first optic and the second optic. The method can also include folding, after the rotating, the intraocular optic assembly while retaining the stanchions in the at least one of between the first optic and the second optic and around one of the first optic and the second optic. The method can also include inserting, after the folding, the intraocular optic assembly in an eye through an incision in a cornea of the eye.

An accommodating intraocular lens device for treatment of an eye having a lens body; internal support; stabilization system; and force translation arm. The lens body includes an accommodating membrane, an annular element, a static element, and a fixed volume of optical fluid filling a sealed chamber of the lens body. The annular element coupled to the perimeter of the accommodating membrane has a shape deformation membrane configured to undergo displacement relative to the perimeter region. The sealed chamber is formed by inner surfaces of the accommodating membrane, shape deformation membrane, and static element. The force translation arm has a first end operatively coupled to the shape deformation membrane and a free end available and configured to engage a ciliary structure of the eye. The force translation arm is moveable relative to the lens body to cause inward movement of the shape deformation membrane. Related methods, devices, and systems are provided.

The present disclosure concerns a curvature-changing, accommodative intraocular lens (IOL) for implantation in the capsular bag of a patient's eye. The IOL includes a fluid optic body having a cavity for containing an optical fluid, the cavity at least partially defined by a sidewall extending around the cavity and defining a diameter of the cavity and a deformable optical membrane intersecting the sidewall around a circumference of the sidewall and spanning the diameter of the cavity. The IOL further includes a second optic body spaced a distance apart from the fluid optic body and a plurality of struts extending from the sidewall and coupling the fluid optic body to the second optic body. The struts are configured such that axial compression of the capsular bag causes the struts to deform the sidewall in a manner that increases the diameter of the cavity, modifying a curvature of the deformable optical membrane.

An intraocular lens (IOL) with a shape-changing optic is provided. The IOL includes an anterior face and/or a posterior face that is fabricated from a poly(dimethylsiloxane) elastomer having a durometer between about 30 Shore A to about 50 Shore A. A chamber is located between the anterior face and the posterior face and includes a silicone oil including diphenyl siloxane and dimethyl siloxane units. The silicone oil has a maximum viscosity of about 700 mm.sup.2/s at 25° C. and has a mean molecular weight of less than about 3,000 Daltons. An IOL is also provided that includes an anterior face and/or posterior face that is fabricated from a polysiloxane that is at least 99% poly(dimethylsiloxane) elastomer.

A method of using an implantable artificial intraocular lens capsule to provide accommodative functionality through forward backward movement. The implantable artificial capsule has a ring with a central opening to accommodate an intraocular lens and at least three haptic arms extending from the ring. Visual accommodation is accomplished by forward or backward motion of the artificial intraocular lens which is made possible by the flexibility or stimuli induced shape change of the haptic arms. Stimuli include (i) mechanical forces acting on the haptic arms for example by the ciliary muscle, (ii) gravitational forces acting on the artificial intraocular lens, (iii) forces acting indirectly on the haptics arms or (iv) external forces including electrical or electromagnetic delivered via the externalized haptics.

A method of inserting an accommodating intraocular lens assembly having at least an optic and ring members that are interconnected to one another with a plurality of stanchions can include winding at least one of the structures relative to at least another one of the other structures about a central optic axis whereby at least some of the stanchions are drawn around an intermediate or middle ring member and in between the optic and an outer ring member. The method can also include folding, after the winding, the accommodating intraocular lens assembly in half while retaining the at least some of the plurality of stanchions in between the optic and the outer ring member. The method can also include inserting, after the folding, the accommodating intraocular lens assembly in an eye through a slit in a cornea of the eye.

Accommodating intraocular lenses and methods of use. The accommodating intraocular lenses include peripheral regions that are adapted to be more responsive to certain types of forces than to other types of forces. For example, the accommodating intraocular lenses can include haptics that are stiffer in an anterior-to-posterior direction than in a radial direction.

Systems, methods, and devices for inserting an intraocular lens (IOL) assembly into an eye may be provided. In an exemplary aspect, the present disclosure is directed to a haptic optic management system. The haptic optic management system may include a housing. The haptic optic management system may further include a plate, wherein the plate is disposed within the housing. The haptic optic management system may further include a clip that engages the plate in the housing, wherein the clip comprises a clip body and a plurality of legs that extend from the clip body.
