POSTERIOR CHAMBER PHAKIC INTRAOCULAR LENS
A posterior chamber phakic intraocular lens comprising a central optical part, a peripheral haptic part comprising a plurality of support elements arranged to lie on a ciliary zonule of an eye, and at least one flexible haptic comprising a reticulated distal region arranged to lay into a ciliary sulcus of the eye.
Accommodating intraocular lens device
An intraocular lens (IOL) device comprising a first lens, a second lens and a circumferential haptic. The first lens comprises a pair of opposing and deformable surfaces and a cavity defined therebetween. The first lens has a first lens diameter. The second lens has a second lens diameter. The circumferential haptic has an outer peripheral edge and couples the first lens and the second lens. A main IOL cavity is defined by the circumferential haptic, the first lens and the second lens. The IOL device is resiliently biased to an unaccommodated state, characterized by the IOL device having a first diameter d.sub.1 in the absence of radial compressive forces exerted on the outer peripheral edge. The IOL device actuates to an accommodated state being characterized by a second diameter d.sub.2 in response to radial compressive forces exerted on the outer peripheral edge, wherein d.sub.1>d.sub.2.
INTRAOCULAR LENSES WITH SHAPE-CHANGING OPTICS
An intraocular lens (IOL) with a shape-changing optic is provided. The shape-changing optic includes an elastic anterior face located anterior to the equator. The anterior face has an anterior surface, a posterior surface, and a periphery. The shape-changing optic also includes a posterior face having an anterior surface, a posterior surface, and a periphery. An elastic side wall can extend across the equator and extend from the anterior face to the posterior face. A chamber can be located between the anterior face and the posterior face. The IOL can further include at least one haptic extending from the periphery of the anterior face, the periphery of the posterior face, or both.
ACCOMMODATING INTRAOCULAR LENS
An intraocular lens (TOL) for implantation within a capsular bag of a patient's eye comprises an optical structure and a haptic structure. The optical structure comprises a planar member, a plano convex member, and a fluid optical element defined between the planar member and the plano convex member. The fluid optical element has an optical power. The haptic structure couples the planar member and the plano convex member together at a peripheral portion of the optical structure. The haptic structure comprises a fluid reservoir in fluid communication with the fluid optical element and a peripheral structure for interfacing to the lens capsule. Shape changes of the lens capsule cause one or more of volume or shape changes to the fluid optical element in correspondence to deformations in the planar member to modify the optical power of the fluid optical element.
Accommodating intraocular lens
An accommodating intraocular lens (AIOL) for implantation within a capsular bag of a patient's eye comprises first and second components coupled together to define an inner fluid chamber and an outer fluid reservoir. The inner region of the AIOL provides optical power with one or more of the shaped fluid within the inner fluid chamber or the shape of the first or second components. The fluid reservoir comprises a bellows region with one or more folds of the bellows extending circumferentially around an optical axis of the eye. The bellows engages the lens capsule, and a compliant fold region between the inner and outer bellows portions allows the profile of the AIOL to deflect when the eye accommodates for near vision. Fluid transfers between the inner fluid chamber and the outer fluid reservoir to provide optical power changes when the eye accommodates.
INTRAOCULAR LENS
A deformable intraocular lens (IOL) comprises a deformable optic, having an annular edge around its periphery, and at least two haptics, each having a proximal portion and a distal portion relative to the optic. Each haptic extends from a different position on the annular edge of the optic and can be compressed. The IOL further comprises at least one tab extending from the annular edge of the optic at a position different from the proximal portion of each of the haptics. The or each tab can adjust the folding characteristics of the IOL, which in turn can control the speed and orientation of the IOL on injection into a patient's eye and ensure greater reliability of desired injection.
Accommodating intraocular lens with meniscus
An intraocular lens includes an annular housing coupled to a first window to form a lensing cavity. Disposed within the lensing cavity is two immiscible liquids, including a first liquid and a second liquid which form a meniscus at an immiscibility interface between the first liquid and the second liquid within the lensing cavity. The intraocular lens includes a flexible reservoir to store a variable portion of the first liquid. The flexible reservoir is disposed about at least a portion of a periphery of the annular housing. The intraocular lens also includes at least one channel linking the flexible reservoir to the lensing cavity to permit a transfer of the first liquid between the flexible reservoir and the lensing cavity. The transfer of the first liquid changes a curvature of the meniscus to adjust optical power of the intraocular lens.
Intraocular lens structure
An intra ocular lens (IOL) for placement in the capsular bag and securing the IOL in an opening in an anterior part of a capsular bag, with an anterior capsular bag flap surrounding said opening. An anterior side, which in use when the IOL is implanted in an eye is directed towards a cornea of the eye. A posterior side, which in use when the IOL is implanted in an eye is directed towards a retina of the eye. The IOL comprises an optical structure, at least two posterior supports to provide support for a posterior surface of an anterior capsular bag flap, and at least two anterior supports to provide support for an anterior surface of an anterior capsular bag flap, when IOL residing inside and outside of the anterior capsular bag flap respectively.
