Document Type and Number:
Japanese Patent JPH06311997
Kind Code:
A
Abstract:
PURPOSE: To block the flow of lachrymal fluid away from the surface of a wearer's eye through a punctal opening and into an associated caniculus effectively and reversibly. CONSTITUTION: A lachrymal fluid control device 20 includes an axle between a tip portion 22 and a head portion 24. The diameter of the axle at the head side is smaller than that at the tip side, and the side wall of the axle inclines outwardly from the head portion to the tip portion. As the side wall is inclined, the plug is kept in a suitable position securely by the downward force onto the control device exerted by the fibroelastosis around the punctal opening 50. In a preferred mode, the axle, having a cylinder-shaped portion at the head side and a cone-shaped portion at the lower part, is coincided with an actual shape of the punctal opening 50.
