По теории Ми для полидисперсных систем рассчитаны спектры сечений ослабления, рассеяния и поглощения для моделей хрусталика в норме и с катарактой. Для апробации модели использованы данные по спектрам аутофлуоресценции хрусталика в норме и при катаракте, полученные с помощью экспериментального офтальмологического спектрофлуориметра с возбуждением УФ светодиодами. В рамках модели проведена оценка степени влияния светорассеяния хрусталика на форму спектра люминесценции. Установлено, что изменения в спектре флуоресценции хрусталиков с катарактой могут быть полностью интерпретированы рассеянием света.</p></abstract><trans-abstract xml:lang="en"><p>The model of the autofluorescence spectrum formation of crystalline lens taking into account light scattering was presented. Cross sections of extinction, scattering and absorption were obtained numerically for models of normal crystalline lens and cataract according to the Mie theory for polydisperse systems. To validate the model, data on the autofluorescence spectra of the normal lens and cataracts were obtained using an experimental ophthalmologic spectrofluorimeter with excitation by UV light emitting diodes. In the framework of the model, the influence of the lens light scattering on the shape of the luminescence spectrum was estimated. It was found that the changes in the fluorescence spectrum of lenses with cataracts can be completely interpreted by the light scattering. </p></trans-abstract><kwd-group xml:lang="ru"><kwd>флуоресценция</kwd><kwd>светорассеяние</kwd><kwd>зрелость катаракты</kwd><kwd>fluorescence</kwd><kwd>light scattering</kwd><kwd>cataract maturity</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">J.
