Abstract

Currently over 50 kinds of intraocular lenses (IOLs) are approved for patient use in the treatment of cataracts and ametropia. These lenses are manufactured from at least 2 kinds of silicones as well as several kinds of acrylic polymers including polyHEMA, poly HOXEMA, a range of polymethacrylate and polyacrylate formulations. We sought to measure spectral mission curves of a range of IOLS in the UV-visible and near IR spectral regions in order to better characterize their optical properties and to provide a baseline from which to assess their alteration following implantation over time. Consideration of how this may best be achieved are discussed. The variable ability of both explanted IOLs and some samples from a range of manufacturers to block UV wavelengths is commented upon.
