Abstract: The present invention relates to lenses that are capable of post-fabrication power modifications. In general, the inventive lenses comprise (i) a first polymer matrix and (ii) a refraction modulating composition that is capable of stimulus-induced polymerization dispersed therein. When at least a portion o f the lens is exposed to an appropriate stimulus, the refraction modulating composition forms a second polymer matrix. The amount and location of the second polymer matrix may modify a lens characteristic such as lens power by changing its refractive index and/or by altering its shape. The inventive lenses have a number of applications in the electronics and medical fields a s data storage means and as medical lenses, particularly intraocular lenses, respectively.

Abstract: Described herein are associative polymers capable of controlling one or more physical and/or chemical properties of non-polar compositions and related compositions, methods and systems. The non-polar composition comprises a host composition having a dielectric constant equal to or less than about 5, and at least one associative polymer which is soluble in the host composition in a concentration between from about 0.1c* to about 10c* and comprises a linear, branched, or hyperbranched polymer backbone having at least two ends and a functional group presented at two or more ends of the at least two ends of the backbone, and wherein the linear, branched, or hyperbranched polymer backbone is substantially soluble in a non-polar composition, and the functional group is capable of undergoing an associative interaction with another functional group with an association constant (k) of from 0.1

Abstract: Described herein are associative polymers capable of controlling a physical and/or chemical property of non-polar compositions that can be used when the non-polar composition is in a flow, and related compositions, methods and systems. Associative polymers herein described have a non-polar backbone with a longest span having a molecular weight that remains substantially unchanged under the flow conditions and functional groups presented at ends of the non-polar backbone, with a number of the functional groups presented at the ends of the non-polar backbone formed by associative functional groups capable of undergoing an associative interaction with another associative functional group with an association constant (k) such that the strength of each associative interaction is less than the strength of a covalent bond between atoms and in particular less than the strength of a covalent bond between backbone atoms.

Abstract: The disclosure concerns altering the mechanical and/or chemical property of a body tissue, particularly an ocular tissue. In specific cases, it concerns altering or stabilizing the shape of the cornea, such as in a subject suffering or at risk for ectasia or keratoconus. In other specific cases, it concerns strengthening the sclera in a subject suffering or at risk for myopia. The invention employs light irradiation of a photoactivatable compound, such as one that applies crosslinking to the tissue, for example.No Suitable Figure.

Abstract: A system for correcting aberrations in an optical system comprising: an optical element and a wavefront sensor, characterised in that the optical element comprises a first polymer matrix and arefraction modulating composition dispersed and freely diffusable within the first polymer matrix, wherein the refraction modulating composition is capable of stimulus-induced polymerization to produce desired changes in the optical element, the first polymer matrix having been polymerised in the presence of the refraction modulating composition.
