| 1 | Geometric-phase intraocular lenses with multifocality显示文摘We demonstrate a new type of multifocal and extended depth of focus(EDOF)intraocular lenses(IOLs)embeddingμm-thin geometric phase(GP)lens layers.As 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 designs.The 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 layer.Bifocal and trifocal GP IOLs are fabricated by radial alignment of anisotropic orientation in UV-curable liquid crystal polymers.After 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. | Seungmin Lee Gayeon Park Senho Kim Yeonghwa Ryu Jae Woong Yoon Ho Sk Hwang In Seok Song Chang Sun Lee Seok Ho Song | 2022 | Light(Science & Applications)2022，11，11： | 1 |
