A stent for use in the nasolacrimal duct of a patient's eye. The stent is used to maintain and improve the patency of the nasolacrimal duct. The stent uses a hollow shaft to create a fluid pathway from the punctum to the inferior meatus. Either the superior or inferior punctum can be selected for insertion of the stent. An inserter is used to position the flexible stent into position. A guidewire attached to the inserter is removed from the stent and it transforms from its collapsed state to its deployed state. A first anchor stabilizes the proximal end of the stent to the punctum and ampulla. A second anchor stabilizes the proximal end of the stent near the inferior meatus. The second anchor can take any of several deployed shapes, such as a pigtail or fins.
