If you suffer from dry, burning, irritated or itchy eyes, you may have dry eye syndrome. Dry eye syndrome is a condition where your eyes either don’t produce enough tears or produce low-quality tears that can’t keep your eyes adequately hydrated. Sometimes the meibomian glands, which produce the oily layer of your tears, found inside your eyelid don’t function properly or are blocked, causing your tears to dry out.
If your tear ducts are blocked, your eye doctor may suggest punctal plugs.
What Are Punctal Plugs?
Punctal plugs are small devices that are inserted into the tear ducts — the puncta — of the eyelids. Another type of plug is inserted into the tear duct, the canaliculus, at a deeper level.
Puncta are small openings in your eyes that drain tears. The plug, which is about the size of a grain of rice, prevents fluid from flowing from the eyes. This ensures that the maximum amount of tears remain on the eyes at all times, resulting in less itching, burning, and redness.
Two Types of Punctal Plugs
Temporary/dissolving plugs are made of a material, such as collagen, that the body absorbs over time. These plugs can last anywhere from a few days to several months in the eye. After refractive surgery, such as LASIK, temporary plugs are frequently used to keep the eye moist. They can also be used to test out punctal plugs to see if they provide dry eye relief.
Semi-permanent plugs are composed of medical plastic, such as silicone or acrylic, that lasts longer. These plugs are made to stay in the eye for years. Your eye doctor can remove them, if necessary.
Another sort of semi-permanent punctal plug is inserted in the canaliculus, which is a deeper section of the tear duct. Once in the eye, these plugs are completely invisible.
How Are Punctal Plugs Inserted?
Your eye doctor will first inspect your eye to determine the optimum type and size of plug for your eyes.
Anesthesia may be used to numb your tear ducts. However, in some cases, you may not need to have your eyes numbed. As the punctal plug is inserted into your eyelid, you may feel some pressure.
After the plugs are inserted, you should be able to resume your normal activities at once.
When and How are Punctal Plugs Removed?
How to remove the plugs and when will depend on which plugs are inserted.
To remove silicon plugs from the tear ducts, your eye doctor will use forceps to gently pull the plugs out. Another option for removing these plugs is to use a saltwater solution to flush them out. The plugs are forced out of the tear ducts and into the nose or throat during this procedure.
Surgery is usually required to remove plugs that are deeper in the tear duct (in the canaliculus).
For most people, punctal plugs don’t cause any problems. However, if you have any eye pain, itchiness, or fear you have an infection, contact your eye doctor right away. The eye doctor will examine your eyes and remove the plugs if necessary.
Are Punctal Plugs for You?
Consult your eye doctor if artificial tears or other eye drops have failed to relieve your dry eye symptoms. If blocked tear glands are the culprit, your doctor might advise you to try punctal plugs.
