A multifocal intraocular lens (MF-IOL) includes a circularly birefringent material with a right-handed index of refraction n.sub.R for a light with a right-handed polarization, and a left-handed index of refraction n.sub.L for a light with a left-handed polarization; and haptics, to position the multifocal intraocular lens inside a capsule of an eye; wherein the multifocal intraocular lens has a right-handed optical power D.sub.R for the light with the right-handed polarization, and a left-handed optical power D.sub.L for the light with the left-handed polarization, wherein D.sub.L/D.sub.R=(n.sub.L−1)/(n.sub.R−1). Some variations of the MF-IOL include stimulus-orientable optically anisotropic constituents. Some classes of the MF-IOL include a self-assembling optically anisotropic compound. A corresponding method of making a MF-IOL is comprising providing stimulus-orientable optically anisotropic constituents as part of an intraocular lens; orienting the optically anisotropic constituents by applying a non-stretching stimulus; and locking-in the oriented optically anisotropic constituents to form the multifocal intraocular lens.

A system/method allowing hydrophilicity alteration of a polymeric material (PM) is disclosed. The PM hydrophilicity alteration changes the PM characteristics by decreasing the PM refractive index, increasing the PM electrical conductivity, and increasing the PM weight. The system/method incorporates a laser radiation source that generates tightly focused laser pulses within a three-dimensional portion of the PM to affect these changes in PM properties. The system/method may be applied to the formation of customized intraocular lenses comprising material (PLM) wherein the lens created using the system/method is surgically positioned within the eye of the patient. The implanted lens refractive index may then be optionally altered in situ with laser pulses to change the optical properties of the implanted lens and thus achieve optimal corrected patient vision. This system/method permits numerous in situ modifications of an implanted lens as the patient's vision changes with age.

An ophthalmic apparatus includes a support structure; a substrate included with the support structure; at least one conductor disposed on the substrate; and a hermetic barrier structure disposed over the at least one conductor. The hermetic barrier structure further includes a stack of alternating flexible insulating material and superelastic metal alloy layers.

A composite light adjustable intraocular lens comprises an acrylic diffractive intraocular lens, having a diffractive structure and haptics; and a silicone light adjustable lens, attached to the acrylic diffractive intraocular lens. The diffractive structure produces constructive interference in at least four consecutive diffractive orders corresponding a range of vision between near and distance vision, wherein the constructive interference produces a near focal point, a distance focal point corresponding to the base power of the ophthalmic lens, and an intermediate focal point between the near focal point and the distance focal point and wherein a diffraction efficiency of at least one of the diffractive orders is suppressed to less than ten percent.

An apparatus has central lens body for providing vision correction for a patient. The lens body has a central aperture and is configured as one of: a diffractive lens or a refractive lens.

An intraocular lens (IOL) based on a metasurface, includes: a front optical lens, a rear optical lens, an equatorial plane, and an optical loop. The front optical lens and the rear optical lens are connected through the equatorial plane. The optical loop is connected with the equatorial plane. A metasurface structure is arranged on the equatorial plane. The metasurface structure includes a plurality of nanostructure units with a phase distribution of a planar axicon lens. A Gaussian beam is generated based on a biconvex lens structure of a conventional IOL, and the phase distribution of the planar axicon lens is loaded through a geometric phase of the metasurface structure, such that a Bessel-Gaussian beam is generated. When the beam is propagated in a free space, a cross section of the beam is not changed along with a propagation distance, such that the Bessel-Gaussian beam keeps a relatively consistent focal plane within a certain propagation distance, thereby realizing characteristics of long focal depth, adjustable refraction, and achromatism.
