Intraocular lens with elastic mask
Intraocular implants and methods of making intraocular implants are provided. The intraocular implant can include a lens body having a lens material and a mask having a mask material. The lens body can be secured to the mask. The mask material can include a modulus of elasticity that is greater than or equal to a modulus of elasticity of the lens material.
POSTERIOR CHAMBER PHAKIC INTRAOCULAR LENS
A posterior chamber phakic intraocular lens including a central optical part, a peripheral haptic part including a plurality of support elements arranged to lie on a ciliary zonule of an eye, and at least one flexible haptic including a reticulated distal region arranged to lay into a ciliary sulcus of the eye.
Optical Devices Having Partial or Incomplete Optic and Associated Methods
An optical device including a partial or incomplete optic configured operatively as an add-on (e.g., supplemental lens/optic) for an (existing) optical element or system, the partial or incomplete optic having an active area configured in relation to the optical element or system such that the partial or incomplete optic controls or changes foci of light incident upon or provided to the active area, but does not control or change foci of light bypassing optically relevant portions of the partial or incomplete optic, and associated methods for enhancing vision.
Phakic intraocular lens
The present invention is a phakic intraocular lens for implantation between an iris and a crystalline lens. The phakic intraocular lens includes a diffraction grating 5 disposed in a lens central part 2 and having circular, coaxial grooves formed thereon, and a support part 3 disposed outside the diffraction grating 5 and supporting the diffraction grating 5. A hole 6 is formed in the center of the diffraction grating 5.
Accommodating intraocular lenses and methods of use
Accommodating intraocular lenses containing a flowable media and their methods of accommodation.
Methods and systems for changing a refractive property of an implantable intraocular lens
A method of altering a refractive property of a crosslinked acrylic polymer material by irradiating the material with a high energy pulsed laser beam to change its refractive index. The method is used to alter the refractive property, and hence the optical power, of an implantable intraocular lens after implantation in the patient's eye. In some examples, the wavelength of the laser beam is in the far red and near IR range and the light is absorbed by the crosslinked acrylic polymer via two-photon absorption at high laser pulse energy. The method also includes designing laser beam scan patterns that compensate for effects of multiphone absorption such as a shift in the depth of the laser pulse absorption location, and compensate for effects caused by high laser pulse energy such as thermal lensing. The method can be used to form a Fresnel lens in the optical zone.
MASKED INTRAOCULAR IMPLANTS AND LENSES
Intraocular implants and methods of making intraocular implants are provided. The intraocular implants can improve the vision of a patient, such as by increasing the depth of focus of an eye of a patient. In particular, the intraocular implants can include a mask having an annular portion with a relatively low visible light transmission surrounding a relatively high transmission central portion such as a clear lens or aperture. This construct is adapted to provide an annular mask with a small aperture for light to pass through to the retina to increase depth of focus. The intraocular implant may have an optical power for refractive correction. The intraocular implant may be implanted in any location along the optical pathway in the eye, e.g., as an implant in the anterior or posterior chamber.
DARKENING FILTER COMPRISING A NON-UNIFORM PATTERN OF SWITCHABLE SHUTTERS
The present disclosure relates to darkening filters 10, 10′ which are suitable for selectively darkening an optically transmissive window 20 for protection from light, in particular from high intensity light. The darkening filter 10, 10′ is mounted in a forward-facing optically transmissive window 20 and comprises a non-uniform pattern 30 of switchable shutters 32 capable of being switching to at least a dark state and a light state by a shutter control system 40. The present disclosure also relates to a method of operating such darkening filters 10, 10′. The present disclosure furthermore relates to vision-protective headgears 100, 100′, welding shields 110 and panes 120 comprising the darkening filters 10, 10′ according to the present disclosure.
HIGH DEFINITION AND EXTENDED DEPTH OF FIELD INTRAOCULAR LENS
Disclosed are systems, devices, and methods that overcome limitations of lOLs at least by providing a phakic or aphakic IOL that provides correction of defocus and astigmatism, decreases higher-order monochromatic and chromatic aberrations, and provides an extended depth of field to improve vision quality. The IOL includes a virtual aperture integrated into the IOL. The construction and arrangement permit optical rays which intersect the virtual aperture and are widely scattered across the retina, causing the light to be virtually prevented from reaching detectable levels on the retina. The virtual aperture helps remove monochromatic and chromatic aberrations, yielding high-definition retinal images. For a given definition of acceptable vision, the depth of field is increased over a larger diameter optical zone IOL.
VARIABLE THICKNESS DYNAMIC MEMBRANE FOR ACCOMMODATING INTRAOCULAR LENSES
Intraocular lenses having an anterior optic with a central, dynamic zone configured to undergo shape change for accommodation that has a differential thickness gradient between a posterior surface and an anterior surface. Related devices and methods are provided.
