Patients that may benefit from the use of punctum plugs are: sufferers of allergies, cataracts, dry eye disorder secondary to contact lens use, and others who experience dry eye disorders. Specific treatment to stop the outflow of tears via a punctal opening (upper/lower) in order to increase tear flow on the surface of the eye. ## Device Story Delta Punctum Plug is a mechanical device designed for insertion into the punctal opening of the eye. It functions by physically blocking the outflow of tears through the upper or lower punctum. By occluding the drainage pathway, the device increases tear volume on the ocular surface, thereby alleviating irritation and discomfort associated with dry eye disorder. The device is intended for use by clinicians to treat patients with insufficient ocular moisture. It provides a passive, mechanical solution to tear retention. ## Clinical Evidence No clinical data provided; substantial equivalence is based on the established nature of the device type and intended use. ## Technological Characteristics Mechanical punctum plug; designed for insertion into the punctal opening to occlude tear drainage. No energy source, software, or electronic components. ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).
