Optical elements capable of post-fabrication modulus change

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 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.

What is claimed is:  
     
         1 . An optical element comprising: 
 a first polymer matrix and    a modulation composition dispersed therein wherein the composition is capable of stimulus-induced polymerization causing a desired change in the elastic modulus.
