摘      要：We demonstrate a new type of multifocal and extended depth of focus(EDOF)intraocular lenses(IOLs)embeddingμm-thin geometric phase(GP)lens *** an emerging approach for lens phase design,the GP modulated IOLs outperform conventional diffractive IOLs in multifocality while completely avoiding the clinically undesirable demand for additional surface patterns to standard monofocal IOL *** number of foci and light splitting ratio of the GP IOLs are adjusted by changing the number of stacked GP layers and the thickness of each *** and trifocal GP IOLs are fabricated by radial alignment of anisotropic orientation in UV-curable liquid crystal *** characterizing the defocus image and modulation transfer function of the GP IOLs,it is expected that GP IOLs will alleviate the most common problems associated with multifocal and EDOF IOLs,blurred vision and photic phenomena caused by light scattering and posterior capsule opacification.
