1. A lacrimal implant insertable into a lacrimal canaliculus, comprising:

  • an implant body, including first and second portions, the implant body extending from a proximal end of the first portion to a distal end of the second portion, the first portion including a cavity;

    a drug insert disposed in the cavity, the drug insert including a polymeric matrix, a therapeutic agent dissolved or dispersed in the polymeric matrix, and a sheath body disposed over at least a portion of the polymeric matrix to define at least one insert exposed surface located at or near the proximal end of the first portion implant body;

    the proximal end of the first portion defining a longitudinal proximal axis and the distal end of the second portion defining a longitudinal distal axis;

    the implant body configured such that, when implanted in the lacrimal canaliculus, an angled intersection exists between the proximal axis and the distal axis for biasing at least a portion of the implant body against at least a portion of the lacrimal canaliculus located at or more distal to a canalicular curvature; and

    wherein the second portion of the implant body includes a longitudinal length having a magnitude less than four times a longitudinal length of the first portion of the implant body.
