Abstract

Studies on polymer materials used in ophthalmological surgery as intraocular implants are presented in this paper. The material under investigation were brand new lenses provided by Alcon. The first lens, model SA60AT, was the basis structure, whereas the other one, model SN60AT, was a structure with an added modification in the form of a blue light chromophore. Results obtained with the use of the positron annihilation lifetime spectroscopy, as well as UV-vis-NIR methods, showed that the structure modified by the chromophore becomes more packed, while the results obtained by means of the UV-vis-NIR methods showed that the modification restricts the blue light transmission.
