Latest Patents

Sunil Kumar Chaubey holds a patent for a "Photo-responsive shape changing polymer composition for colored optical lens." This invention includes photoinitiators that absorb light in the range of about 400 nm to about 700 nm, a cross-linked polymer matrix, and a polymerizable composition. The photopolymerization of the polymerizable composition sorbed in the cross-linked polymer matrix results in a shape change that manifests in the change in the refractive properties of the composition. The light dose required to effect the shape change, lock-in dose, and the photobleaching dose are determined by the choice of the photoinitiator, electron donor, and hydrogen donor. These compositions are particularly useful in the fabrication of colored lenses, especially intraocular lenses.
