  • Abstract

With the recently developped fabrication te-chnique for optical aspheric surface at Nihon Kogaku Co. Ltd., the authors designed and fab-ricated an aspheric plus preset lens for slit la-mp fundus microscopy with multilayered co-ating and describe the merit and clinical use of this lens. Results of general clinical appli-cation of their lens was so satisfactory by re-duction of aberrations and large field of obser-vation and observations of fundus with optical section was also so fascinating. The authors estimate the plus preset lens (El Bayadi lens) for biomicroscopy of fundus higher than Hruby lens.
