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 of 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 as data storage means and as medical lenses, particularly intraocular lenses, respectively.
An optical element comprising:
A lens comprising:
An intraocular lens comprising:
A method of implementing an optical element having a refraction modulating composition dispersed therein, comprising:
A method of implementing an intraocular lens having a refraction modulating composition dispersed therein and implanted within the eye, comprising:
A method of implementing an intraocular lens having a refraction modulating composition dispersed therein and implanted within the eye, comprising:
A lens comprising:
A lens comprising:
An intraocular lens comprising:
A method of adjusting the refraction of a lens having a refraction modulating composition dispersed therein, comprising (a) exposing at least a portion of the lens to an external stimulus wherein the external stimulus induces the polymerization of the refraction modulating composition in the portion of the lens exposed to the stimulus, such that the stimulus causes a desired change of refraction, without subsequent removal of the refraction modulating composition.
