Abstract (en)
[origin: WO2019119098A1] Ophthalmic devices are used to treat a variety of eye conditions. Such devices include intraocular lens (IOL) implants, contact lenses, intraocular telescopes, and the like. Such ophthalmic devices typically include one or more lenses to interact with visible light. According to an aspect of the disclosure, there is provided an ophthalmic device comprising a biocompatible polymer body and a metalens. The metalens is encapsulated by the polymer body. The metalens comprises a substantially transparent substrate and a plurality of subwavelength structures arranged on the substrate in a pattern to interact with visible light. subwavelength structures comprise a dielectric material such as titanium dioxide.
