Punctal plug

Punctal plug is a small medical device that is inserted into the tear duct (puncta) of an eye to block the duct. This prevents the drainage of liquid from the eye. They are used to treat dry eye.

Overview

A punctal plug, also known as a punctum plug, occluder or a lacrimal plug, is a tiny device inserted into the tear duct (puncta) of an eye to block the duct. This prevents the drainage of liquid from the eye. They are used to treat dry eye, a condition that occurs when individuals do not produce enough tears or if the tears evaporate too quickly.

Types of Punctal Plugs

There are two types of punctal plugs: semi-permanent and dissolvable. Semi-permanent plugs are typically made of long-lasting materials such as silicone. Dissolvable plugs are made of materials that will eventually be absorbed by the body, such as collagen.

Procedure

The procedure to insert a punctal plug is quick and often painless. The eye doctor will first examine the eye to determine the size of the plug needed. The plug is then inserted into the puncta, which is located in the inner corner of the eye.

Risks and Complications

While punctal plugs can effectively relieve the symptoms of dry eye, they are not without risks. Potential complications include eye irritation, excessive tearing, and displacement or loss of the plug. In rare cases, an infection may occur.
