Many people suffer from dry eye, when their eyes do not make enoughtears or the right quality of tears.Eye drops are often used to treat dry eye. However, some people find that having punctal plugs inserted into their eyes can help make them more comfortable.

Punctal plugs are tiny devices that are placed in the eyes tear ducts (called puncta). Puncta are the tiny openings that drain tears from your eyes. About the size of a grain of rice, the plug stops fluid from draining from the eye. This helps keep the eyes surface moist and comfortable, relieving itchy, burning and red eyes.

Punctal plugs are also called punctum plugs, lacrimal plugs or occluders. Usually they are inserted in the puncta of the upper or lower eyelids, or in both. Another type of plug is placed in a deeper part of the tear duct (the canaliculus).

These are made of a material (such as collagen) that gradually breaks down and is absorbed by the body. These plugs can last in the eye from a few days to months. Temporary plugs are often used to keep the eye moist after having refractive surgery, such as LASIK. They are also used when you want to try out punctal plugs to see if they help relieve your dry eye.

These are made of a longer-lasting medical plastic (such as silicone or acrylic). These plugs are designed to stay in the eye for years. They can be removed by your ophthalmologist if needed.

Another type of semi-permanent punctal plug is placed in a deeper part of the tear duct called the canaliculus. These plugs cannot be seen at all in the eye.

First your eye doctor will examine your eye to figure out the best type and size plug for your needs.

Your doctor may numb your tear ducts with anesthesia. In some cases, you may not need to have your eyes numbed. You may feel some pressure as the punctal plug is placed in your eyelid.

After the plugs are inserted, you are usually able to return to your normal activities right away.

As with any treatment or procedure, punctal plugs can have possible risks and side effects.

The most common side effect is having a scratchy orirritating feeling in the corner of your eye. Many people find this feeling goes away or they simply get used to it.

Other side effects and risks may include the following:

Most people find punctal plugs do not cause any problems. However, side effects can happen. If you feel any eye pain, scratchiness or if you think you have an eye infection, tell your eye doctor right away. They may choose to remove the plugs.

How the plugs are removed depends on which type you have. To remove silicon plugs, your eye doctor will use forceps to gently pull the plugs from the tear duct. Another way to remove these plugs is by flushing them out with a salt water solution. This method forces the plugs out of the tear ducts into the nose or throat.

Plugs that are deeper in the tear duct (in the canaliculus) are removed with surgery.

If artificial tears or other eye drops have not relieved your dry eye symptoms, talk with your ophthalmologist. They may recommend trying punctal plugs.
