ABSTRACT:
The invention concerns lachrymal plugs, and methods for setting said devices. It concerns a lachrymal plug (10) designed to be inserted in the lachrymal canaliculi (5), said plug, optionally provided with an axial duct, comprising on its outer walls flexible elements (11) foldable on said walls to enable the plug to be inserted in the lachrymal duct and adapted to straighten up once the lachrymal plug is set, so as to maintain the latter in position. The invention generally concerns means for controlling the flow of tears running from the surface of the eye towards the nasal cavity.
