Synthesis of Soft Polysiloxane-urea Elastomers for Intraocular Lens Application
Published on: March 8, 2019
Abstract:
A technique for accurately figuring very thin, lightweight lenses is discussed. The phase change required to focus a plane wave into a point is calculated and photographically plotted with exposure proportional to phase (scaled from 0 to 2pi). The plot is photoreduced and the photoreduction is etched, with the depth of etch approximately proportional to the exposure. The result is a kinoform lens. Photographs taken with a kinoform lens are included.
