Abstract: An implantable lens device has a diffractive surface defining an optical axis. The diffractive surface comprises a relief pattern extending concentrically on the surface and having a sequence of annular concentric steps characterized by alternating heights, wherein an innermost step of the relief pattern has a largest height among all other steps.

Abstract: An intraocular lens comprises a lens body customized for astigmatism in a particular eye. For the customization to work, the astigmatism in the lens has to be aligned with astigmatism in the eye. Thus the intraocular lens comprises four protrusions arranged outwardly around the lens body to form the four corners of a substantially rectangular profile. The profile locks the intraocular lens into a position of rotational stability when inserted into a capsular bag, thus preventing rotation of the intraocular lens, which would otherwise tend to occur both immediately after insertion into the capsular bag and later on during growth, shrinkage or other change to the capsular bag. The Intraocular lens may additionally be customized for other eye conditions and a multi-focal embodiment is also disclosed.

Abstract: Polymeric and co-polymeric compositions useful for preparing ophthalmic and ocular devices, such as implantable intraocular lenses (IOL) and contact lenses, and processes of forming the compositions and devices are provided. The disclosed polymeric or co-polymeric composition may include a curcuminoid compound as a UV-blocker, and is derived from a pre-polymerization mixture of monomers which comprises at least 50 weight percents acrylate monomers and exhibiting visible light transparency and ultraviolet light opacity. The disclosed co-polymeric composition may alternatively, or in addition, be derived from a pre-polymerization mixture of defined monomers.

Abstract: Provided herein is a multifocal ophthalmic device comprising a lens body being formed with a plurality of concentric annular zones separated by slanted steps which effect both diffraction and refraction of incident light, while being devoid of any diffractive or refractive power, whereas the lens body is made from a co-polymeric composition based on less than 75% aromatic acrylate monomers, and includes a curcuminoid compound as a UV-light stabilizer; as well as use of the device for treating ophthalmologic and/or esthetic condition associated with an eye.

Abstract: A lens device structurally adapted to be positioned in the chamber of the eye, preferably the posterior chamber of the eye is disclosed. The device according to some embodiments of the present invention comprises a generally circular optical section characterized by at least one optical power, two generally flat haptic structures at radially opposite sides of the optical part, and a vaulted section connecting the optical section and the haptic structures. In some embodiments, the device comprises at least one opening for allowing flow of liquid, through the device, between the posterior chamber and the anterior chamber of the eye.

Abstract: A multifocal lens device is disclosed. The device comprises, a lens body having two opposite sides, wherein a first side has an aspheric profile and a diffractive pattern formed thereon, and the second side has a toric profile and is devoid of any diffractive pattern. In some embodiments of the present invention the diffractive pattern covers at least 80% of an area of the aspheric profile.
