ABSTRACT:
A canalicular implant for insertion through the punctum of the eye and the method of manufacture. The implant is fabricated by cutting suture-like material, such as catgut, of the appropriate diameter to the desired length. The ends of the implant are rounded and polished after cutting by abrasive polishing to remove any sharp edges and burrs formed by the cutting process. This produces an implant with various degrees of rounding at the ends depending on the duration and type of abrasive polishing used. The method of abrasive polishing may comprise tumble polishing, vibratory polishing, or other methods of agitation utilizing dry or wet media comprised of beads, forms, abrasive powders, or other similar substances or combinations of these media.
