Lacrimal punctum plug

Lacrimal punctum plugs are small, sterile devices placed into the tear ducts (punctal openings) to block fluid drainage. Clinically, they help manage chronic dry eye by retaining moisture in the eye’s surface, reducing irritation and discomfort for patients with conditions like Sjögren’s syndrome or evaporative dryness.

These devices are typically single-use and regulated as medical devices, with classification and supply rules varying by jurisdiction. They are not reusable and must meet strict manufacturing and sterility standards to ensure safe, temporary occlusion of the punctum.
