A reversible, flexible, lacrimal duct occluder is formed of a shaft having a low profile cap at one end and a rounded tip at the other end. At least one, preferably 1-3, conical ranges are forward on the shaft between the ends. The rounded tip enters the punctum followed by leading edge of the range(s) until the occluder bends and enters the horizontal canalicular canal. A series of occluders having 1-3 ranges and varying lengths can be provided to accommodate the different canalicular geometries of different individuals. The occluder is readily inserted without the need to use any special introducer tool and is easily removed from the canaliculus of the patient.

A reversible, flexible lacrimal duct occluder adapted to enter the punctum opening and block a canalicular canal having a vertical canaliculus connected to a horizontal canaliculus comprising in combination a low profile cap having a width larger than the punctum opening; a shaft having distal end and a proximal end connected to the cap; a rounded tip connected to the distal end of the shaft; and at least one rearwardly tapered conical ramp section mounted on said shaft between said ends and the diameter of the ramp being sufficient to block said canal and the distance between said ends being greater than the length of the vertical canaliculus such that the shaft bends and enters the horizontal canaliculus.
