  • Publication number: 20200347167
    Abstract: Disclosed are co-polymers which are produced from reactive monomer mixtures and which have both high refractive index and a high Abbe number. These materials are well suited for use as implantable ophthalmic devices and have a refractive index which may be edited through application of energy. When used for an intraocular lens, the high refractive index allows for a thin lens which compresses to allow a small incision size.
