  • Implantation Tool for Intraocular Lenses
    Publication number: 20080255579
    Abstract: The object of the invention is to permit a smooth advance movement of intraocular lenses (25) by means of a compact design of the implantation tool (1) and a short operating cycle, the push rod in the main body (2) of the implantation tool (1) being driven by a two-stage hydraulic mechanism (3), wherein a connectable cannula (23) with roller (24) forms the sterile storage container for the intraocular lens (25) and, after replacement of the sterile storage fluid by a lubricant fluid, gently transports it into the eye ready for implantation.

  • Method and apparatus for folding a resilient intraocular lens
    Patent number: 5190553
    Abstract: In a method and apparatus for folding a resilient intraocular lens, the l is fixed on a support surface and then folded by means of two pressing members which are moved synchronously towards each other in such a way that the intraocular lens conforms on a slightly reduced scale to the interior of a tube member of a lens implantation instrument. The lens is then released from its support surface and pressed into the interior of the implantation instrument tube member.
