Accommodating intraocular lens

Номер: US20120078364A1

Автор: Donald C. Stenger

Принадлежит: Individual

An Accommodating Intraocular Lens (AIOL) is disclosed herein, that is comprised of a flexible optic and a flexible haptic rim that conforms to the human eye capsule. The spherical or custom shape of the optic is engineered to be maintained during accommodation through the mechanical/optic design of the implant and the interaction between the implant and the naturally occurring position and actuating forces applied through ciliary muscles/zonules/and capsule as the brain senses the need to increase the diopter change or magnification when an object of fixation approaches the eye. The axial relocation or position of the AIOL may also be further adjusted anatomically to further improve the affect needed to achieve improved accommodation. Optionally, the Accommodating Intraocular Lens (AIOL) is foldable or injectable for delivery of the lens into the eye.

Pre-stressed haptic for accommodating intraocular lens

Номер: US20130030525A1

Автор: Daniel G. Brady, Edward P. Geraghty, Randall L. Woods, Timothy R. Bumbalough

Принадлежит: Abbott Medical Optics Inc

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. The haptic may be pre-stressed before the optic is placed within it. After such placement, the pre-stress may be relieved, and the haptic may produce stress in the optic. The pre-stress may produce a radial tension or a radial compression in the optic. Alternatively, once the optic is placed within the haptic, both may undergo a process that changes the size and/or shape of one with respect to the other, causing a stress within the optic. This process may produce a radial tension or a radial compression in the optic. The haptic may include an annular ring having outer and inner diameters that may depend on the stiffness of the haptic.

An intraocular lens has a polymeric optic defined by a harder posterior layer and a softer anterior layer. Haptics having a fulcrum attached to the posterior layer and a resistance arm attached to the anterior layer are provided. A bias is provided to the haptic to rotate the haptics about the fulcrum and cause the resistance arm to deform the softer anterior layer about the harder posterior layer to increase the optical power of the lens. As the haptic rotates, it axially displaces the optic anteriorly to additionally increase the optical power. The optical power is adjustable in response to stresses induced by the eye. The haptics are subject to a pre-bias that urges the haptics to rotate or bend about the fulcrum. Temporary restraints are provided to the haptics to retain a stressed shape of the lens against the bias during a post-implantation healing period.

Принадлежит:

An implantable ophthalmic device with one or more optical elements coupled to one or more shape-memory members provides dynamically variable optical power to restore lost accommodation in individuals suffering from presbyopia or aphakia. Running current from a power supply through the shape-memory members causes the shape-memory members to heat up. Once the current heats the shape-memory members past a forward phase-transition temperature, the shape-memory members change shape, which, in turn, causes the optical element(s) to move, yielding a corresponding change in effective optical power. Cooling the shape-memory members (e.g., by reducing or stopping the flow of current) below a reverse phase-transition temperature causes the shape-memory members to return to their original shape, which, in turn, restoring the optical element(s) to their original positions and returning the effective optical power to its original level. 1.

An accommodating (re-focusable) lens system a body of which includes, upon being assembled, first and second individual lenslets having first and second optical portions sequentially disposed along an optical axis. Change in optical-power accommodation of the system is achieved by changing an applanated area of contact between the lenslets in response to force applied to the lenslets and transformed into an axial force. In specific case, the first and second lenslets form an intraocular lens (IOL) and have respective haptic portions, interlocked as a result of rotating of one lenslet with respect to another such as to bring first and second lenslets in contact at an axial point. The applanated area of contact is changed, then, in response to a radially-directed force caused by a change of distance between the interlocked ends of the haptics and transferred to the optical portions through the interlocked haptics. When installed in a natural lens capsule after the cataract extraction, the optical power of such IOL is gradually modifiable due to a change of curvature of the capsule caused by operation of a ciliary muscle. 1.

An intraocular lens and a method of constructing the intraocular lens are described. The intraocular lens is implanted in a human eye to treat conditions of the eye. The intraocular lens includes a central deformable optic and an annular ring coupled to the deformable optic. The intraocular lens is made by subjecting the deformable optic to compressive forces that reduce the optical power of the deformable optic, and then molding the annular lens to the deformable optic while the deformable optic is undergoing the compressive forces. Once the compressive forces are released, the deformable optic stresses the annular ring along a radial axis of the deformable optic when the intraocular lens is in a natural, unstressed state. The stress or tension between the deformable optic and the annular ring keep the deformable optic from developing deformities that cause visual aberrations. 1.

An accommodating (re-focusable) lens system a body of which includes, upon being assembled, first and second individual lenslets having first and second optical portions sequentially disposed along an optical axis. Change in optical-power accommodation of the system is achieved by changing an applanated area of contact between the lenslets in response to force applied to the lenslets and transformed into an axial force. In specific case, the first and second lenslets form an intraocular lens (IOL) and have respective haptic portions, interlocked as a result of rotating of one lenslet with respect to another such as to bring first and second lenslets in contact at an axial point. The applanated area of contact is changed, then, in response to a radially-directed force caused by a change of distance between the interlocked ends of the haptics and transferred to die optical portions through the interlocked haptics. When installed in a natural lens capsule after the cataract extraction, the optical power of such IOL is gradually modifiable due to a change of curvature of the capsule caused by operation of a ciliary muscle. 1.

An accommodative intraocular lens is described that provides monofocal vision at multiple pre-defined focal points during accommodation. The intraocular lens includes a lens element having a series of stacked optics that can be formed utilizing multiple different materials, each of which can have a different stiffness. In an implanted, disaccommodated state, the lens element can have a pre-defined curvature to thus define a first or base focal point of the intraocular lens. Upon accommodation of the patient's eye, the optics can be compressed and/or deformed at differing intervals so as to provide the intraocular lens with three or more distinct focal points. As an alternative, the lens element can include optics formed with multiple sets of haptic elements having varying haptic stiffnesses to vary compression of the optics in order to provide the intraocular lens with multiple focal points. 1. An intraocular lens comprising:a lens element comprising a first optic, a second optic, a third optic, and a fourth optic, wherein the second optic is formed of a material of a first stiffness, the third optic is formed of a material of a second stiffness, and the first optic and the fourth optic are formed of a material of a different stiffness than the first stiffness of the material of the second optic and the second stiffness of the material of the third optic;at least one haptic element connected to the lens element, wherein movement of the at least one haptic element causes compression of at least the second optic against the third optic; andwherein deformation of the second optic with respect to the first optic provides a first focal point and deformation of the third optic with respect to the fourth optic provides a second focal point distinct from the first focal point.2.
