UV-blue-light-absorbing photochromic intraocular lens for protection against age-related macular degeneration development

摘要

Abstract: In the past, UV-blue-absorbing intraocular lenses (IOLs) were developed and then have been implanted to more than 200,000 patients. Recently, new UV absorbing IOLs, named `IOL-Photochrom' were invented. The latter have photochromic properties, mainly in the blue part of visible spectrum. Under low illumination their spectral transmission is similar to that of natural human lens of young individuals. On the other hand, in bright light of sunny days the transmission is the same as that of the natural lens of oldmen.!7
