Provided herein is a lacrimal stent that includes a flexible tube. The flexible tube includes a first distal end, a second distal end, and an elongated body between the first distal end and the second distal end. A first magnet is arranged at the first distal end of the flexible tube, and a magnetic material is arranged at the second distal end of the flexible tube. When the first distal end of the flexible tube is inserted into a lacrimal sac of an eye through a first punctum and the second distal end is inserted into the lacrimal sac of the eye through a second punctum, a magnetic attraction between the first magnet and the magnetic material causes the flexible tube to flex so that the first magnet of the first distal end magnetically engages the magnetic material of the second distal end.
