  • Patent number: 4660546
    Abstract: An implant and method for treating external human eye conditions due to a deficiency of tears. The method includes the temporary blockade of the canaliculus of a patient without resorting to a surgical stitch, observing the response of the patient's eye to the temporary blockade and, if an improvement is observed, placing an implant within the horizontal portion of at least one of the canaliculi of the patient's eye. The temporary blockade may be produced by the placement of a piece of catgut in the canaliculus. The implant is constructed of a material that is nonabsorbable by the human body and is constructed to facilitate placement into and removal from the canaliculus.
