A blade insert illumination system includes one or more illumination elements composed of a transparent or semitransparent polymer that is preferably biocompatible and sterilizable. The illumination elements operate as a waveguide and may incorporate optical components such as, for example, facets, lenses, gratings, prisms and or diffusers to operate as precision optics for customized delivery of the light energy. The illumination elements may be modular, allowing components to be mixed and matched for different sizes of blade retractors, or may be a single integrated unit.
