Abstract

An implantable ophthalmological device (10) in the form of a punctal plug or canalicular implant is configured for use at or near the nasolacrimal drainage system. In a deployed state, the device (10) may include an elongated body (25), an anchor (15) operably connected to the elongated body (25), a radially expanding occlusive feature disposed on an outer circumference of the elongated body (32), and a flange (30). The elongated body (25) may define a lumen (35) configured to receive a pharmacological treatment (55). The device (10) is made of a shape memory material such as a shape memory polymer.
