Abstract

Abstract Intraocular lens (IOL) made on Polymethylmethacrylate (PMMA) has been irradiated by a UV lamp at different exposure times, in air and at room temperature. The macromolecular modifications induced in the lens have been investigated using attenuated total reflectance (ATR) coupled to Fourier transform infrared (FT-IR) spectroscopy and Optical spectroscopy. Particular attention was devoted to the study of chemical modifications by UV irradiation, which induced chain scissions in the superficial PMMA layers. Results demonstrated that the lens transmission to the visible radiation is not particularly reduced by a long exposition to UV radiation at a fluence of 200 mJ/cm2, up to 19 h.
