摘要： An ophthalmic multifocal switchable lens includes a deformable element manifesting elevated strain with a formable surface of a multifocal surface shape to provide far and near vision. A transparent chamber is filled with optical matching fluid adjacent to the side of the deformable element opposite to the formable surface. The optical matching fluid has a refractive index that matches a refractive index of the deformable element material. A holding chamber is also filled with the optical matching fluid and connected with the transparent chamber with a means for preventing the optical fluid from being transported from the holding chamber to the transparent chamber which would reduce a strain of the deformable element. A split of light between far and near vision of the multifocal switchable lens changes upon a removal of the means to allow a flow of the optical matching fluid into the transparent chamber.

摘要： A lens includes a switchable optical element having an optical substrate with a diffraction surface. A substrate cover forms an internal chamber with the optical substrate. An elastic membrane in contact with the diffraction surface of the substrate forms an active chamber. Through channels are placed through the optical substrate's thinnest parts of the grooves connecting the active and internal chambers. The switchable optical element changes focus positions between one focus with the optical fluid filling the active chamber and the elastic membrane taking a non-periodic shape with the membrane's surface forming a refractive shape of certain curvature and another focus where the optical fluid is transported from the active chamber through the through channels to the internal chamber for the elastic membrane to conform to the diffraction surface shape of the optical substrate with the membrane's surface forming diffractive surface of periodicity of the diffractive guiding surface.

摘要： One disclosed embodiment of an intraocular implant includes a lens body. The lens body comprises a diffractive optical surface (115) having diffractive properties which produce an interference pattern. The lens body is sized and shaped for placement in an anterior portion of a human eye. The lens body is sufficiently flexible to change the shape of the diffractive optical surface in response to ciliary muscle (60) action so that the interference pattern is modified.

摘要： An accommodating intraocular lens (100) implantable in an eye. The lens comprises an anterior portion having an anterior biasing element and an anterior optic having refractive power (106). The lens further comprises a posterior portion having a posterior biasing element and a posterior optic having refractive power (118). The anterior optic and the posterior optic are relatively moveable in response to action of the ciliary muscle to change the separation between the optics and the refractive power of the lens. The lens has an aberration-inducing force characteristic of about 70 mg to about 115 mg to allow aberration-inducing relative movement of the optics when the lens is in the eye, thereby adding optical aberration to the lens which increases depth of focus of the lens. In one variation, the lens has an aberration-inducing force characteristic of 70 mg to 115 mg. Related methods are also disclosed.

摘要： A multi-piece intraocular lens (IOL) has an optic constructed of an elastomeric plastic and an opposing pair of attachment members (haptics) constructed of a rigid plastic material. The optic or haptics have one or more small, tear drop-shaped, inlet recesses formed into each from a peripheral edge region. The haptics or optic are formed having peripheral edge protuberances matching in size, shape and position corresponding optic or haptic inlet recesses. The protuberances dovetail into the corresponding inlet recesses and are cemented therein to lock the haptics and optic together. Methods for manufacturing a multi-piece IOL include forming the haptics from a modified haptic blank and the optic from a modified optic blank. After the haptic or optic protuberances are dovetailed and cemented into the optic or haptic inlet recesses, the haptics and optic are milled or lathed from the respective haptic and optic blanks to provide a completed multi-piece IOL.

摘要： A narrow profile, glare reducing, posterior chamber intraocular lens comprises an optic having an anterior surface and a posterior surface and an optical axis. The posterior surface is formed having two adjacent peri-axial, stepped imaging zones, the two imaging zones having the substantially the same optical power. A transition zone between the two imaging zones preferably has a surface of continuous curvature shaped to reduce direct glare from light incident on the transition zone in an individual's eye in which the intraocular lens is implanted by internal reflection of direct light incident on the transition zone. Attachment members joined to the optic position the intraocular lens in an eye with the optical axis of the optic generally aligned with the optical axis of the eye. In variations, the transition zones are formed at the optic edge to minimize direct and indirect in the eye of an individual wearing the intraocular lens.
