摘要:
Provided herein is a multifocal ophthalmic device comprising a lens body being formed with a plurality of concentric annular zones separated by slanted steps which effect both diffraction and refraction of incident light, while being devoid of any diffractive or refractive power, whereas the lens body is made from a co-polymeric composition based on less than 75% aromatic acrylate monomers, and includes a curcuminoid compound as a UV-light stabilizer as well as use of the device for treating ophthalmologic and/or esthetic condition associated with an eye.
