Optical Properties of Human Eye Cataractous Lens in vitro in the Visible and Near-IR Ranges of the Spectrum

Abstract

The spectral dependences of the absorption coefficient, scattering coefficient, scattering anisotropy factor, and transport scattering coefficient for human eye lens in vitro at different stages of cataracts were studied. The spectra of the absorption coefficient and transport scattering coefficient were obtained for the spectral range 400–2300 nm, and the spectra of the scattering coefficient and the scattering anisotropy factor were obtained for the spectral range 400–1800 nm. The wavelength regions in which the spectra of the studied optical characteristics of human eye lens do not differ significantly and, conversely, differ significantly for the samples with different stages of cataract were identified.
