A punctal plug and method of treating dry eyes are provided. The punctal plug has two or three layer structure and contains at least one drug, for treating conditions such as dry eyes contained in a core, a potion of which is covered by a drug impermeable shell such that drug can radially diffuse from the core. The punctal plug can be inserted into a patient's upper punctum, lower punctum, or both to deliver the drug for an extended period of time. The drug for treating dry eyes can be, for example, cyclosporine A. The plug can also be used for extended delivery of ophthalmic drugs.

Multi-piece punctal plug
A multi-piece punctal plug has one or more superficial plugs connected to an anchor plug deeper in the naso-lacrimal canaliculus. The anchor is fixed to the wall of the lacrimal duct while the superficial plugs are axially and detachably secured to the anchor plug so that the multi-plug complex may be inserted or removed together as one, or the superficial plugs may be detached separately and replaced securely without disturbing the anchor. Removal and insertion is accomplished by a specific tool having an end for engaging the plugs.
