Abstract
The present invention relates to novel materials particularly useful for ophthalmic applications and methods for making and using the same. More particularly, the present invention relates to relatively soft, optically transparent, foldable, high refractive index materials particularly suited for use in the production of intraocular lenses, contact lenses, and other ocular implants and to methods for manufacturing and using the same.
Claims6
A copolymer comprising:
- a) a high refractive index monomer comprising;
- wherein:
- R1-R4 are separately and independently, H, X, or Rc;
