What Is a J-Shaped Punctal Plug?
A J-shaped punctal plug is a small device placed in the tear duct opening called the punctum. The goal is to slow tear drainage so the eye surface stays wet longer, which can help dry eye symptoms. ?J-shaped? usually describes the plug's profile, which can help it sit more securely at the punctum. Punctal plugs come in different designs and materials, including temporary dissolving types and longer-lasting silicone types. Placement is usually quick in clinic and does not require an incision.
