title: [Spectral characteristics of intraocular lenses and injury to the retina caused by visible light].
abstract: It has been shown that intraocular lenses (IOL) prepared from polymethylmethacrylate and silicon let pass the light of short-wave visible and long-wave spectrum regions. Unlike natural lens, IOL have no yellowish coloration, which results in the appearance of chromatic aberrations and brightness of IOL during implantation. Mechanisms of damaging effects of visible light on the retina were studied. It has been shown that a week after the rat eyes were illuminated the waves "a" and "b" ERG were inhibited. At the ultrastructural level damage of the cells of the retinal pigment epithelium and of the retinal layers formed by photoreceptor cells took place. Dynamics of the damage of tissue structures of the retina by visible light was investigated. It is suggested that application of colored lenses and prophylaxis by the inhibitors of free radical oxidation will protect the retina from photochemical damage.
