Intracanalicular implant for horizontal canalicular blockade treatment of the eye
First Claim
1. An implant for the complete insertion into the canaliculus of the human eye comprising a substantially cylindrical, solid element constructed of a material that is non-absorbably by the human body and having a diameter of approximately 0.3-1.2 mm capable of being completely insertable into the horizontal portion of the canaliculus of the human eye without protrusion from the canaliculus and discomfort to a human and yet preventing the drainage of tears through the canaliculus, said element having a tapered end to facilitate implantation into and removal from the canaliculus.

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.
