Chromatic aberration and spectral dependency of extended-range-of-vision intraocular lens technology [PDF]
Scientific Reports, 2023 This study compared the optical quality and chromatic performance of refractive-diffractive intraocular lenses (IOLs) that are designed to extend the range of vision of pseudophakic patients and alter chromatic aberration.

Altering chromatic aberration: how this latest trend in intraocular-lens design affects visual quality in pseudophakic patients [PDF]
Eye and Vision, 2023 Background Chromatic aberration of the eye results from the dispersion of polychromatic light at the interfaces of ocular media. An intraocular lens (IOL) based approach utilizing the diffractive-multifocal principle has been proposed for its correction,

Measurement of Longitudinal Chromatic Aberration in the Last Crystalline Lens Surface Using Hartmann Test and Purkinje Images [PDF]
Sensors, 2022 Research has shown that longitudinal chromatic aberration (LCA) of the human eye is generated across all of the eye’s optical surfaces. However, it may not be necessary to measure the LCA from the first surface of the cornea to the retina, as it is known

First- and third-order chromatic aberrations in Glaser magnetic lens for object magnetic immersion
Heliyon, 2023 In this paper, the Gaussian optical properties and the first- and third-order isotropic and anisotropic chromatic aberrations of the Glaser magnetic lens have been derived analytically and then calculated numerically based on two methods: the ...
