Disclosed are compositions which are produced from reactive monomer mixtures and which have both high refractive indexes and high Abbe numbers. These materials are well suited for use as implantable ophthalmic devices and have a refractive index which may be edited through the application of energy. When used for an intraocular lens, the high refractive index allows for a thin lens which compresses easily through a small incision. Some compositions are suitable for use as intraocular lenses, phakic intraocular lenses, contact lenses, orthokeratology lenses, rigid gas permeable lenses, corneal inlays, corneal outlays, or corneal inserts.
