Punctal Plugs for Dry Eye

Punctal plugs are another type of device designed to help provide relief from dry eye symptoms. They are small devices which are placed in the tear ducts (puncta) of the eyes, and help prevent fluid from draining from the eyes. This helps keep the surface of the eyes more moist, and to relieve the itching, burning sensations that come with dry eye.

The Role of Punctal Plugs in Alleviating Dry Eye and Excessive Tearing

At Specialty Vision, we frequently encounter patients suffering from ocular discomfort due to dry eyes or excessive tearing. Over the years, we as eye care professionals have honed a range of strategies to tackle these issues. One such potent, non-invasive solution that has emerged is the use of Punctal Plugs.

Punctal plugs are tiny devices, about the size of a grain of rice, that are inserted into the tear ducts (also known as puncta) of the eyes. They play a pivotal role in assisting the draining of fluid from the eyes, thereby maintaining increased moisture levels. This alleviates the painful itching or burning sensation often associated with dry eye.

These plugs are generally inserted into the puncta in either the upper or lower eyelids or both if necessary. There are also different types of plugs designed to be placed in another part of the tear duct, known as the canaliculus. Their robustness and adaptability make punctal plugs an invaluable tool in our optometry toolkit.

The Connection Between Tear Ducts and Eye Moisture

The Connection Between Tear Ducts and Eye Moisture

Tear ducts, also known as canaliculus, are vital for maintaining a healthy tear film on your eyes' surface, thus ensuring consistent surface moisture. They are responsible for the drainage of tears from your eyes to your nose. However, if the tear duct openings drain tears too quickly or excessively, dry eyes may result. On the flip side, blockages can cause watery eyes or epiphora, a condition known as excessive tearing.

Punctal Plugs to the Rescue

Punctal Plugs to the Rescue

Punctal plugs act as a dam in the tear drainage system, thus increasing the eye's tear film and surface moisture to relieve dry eye. Alternatively, they can help control excessive tearing by regulating the flow of tears.

There are generally two types of punctal plugs:

  1. Dissolvable (absorbable): Made from materials like collagen, these temporary plugs dissolve over time. They're a great short-term solution, often used following LASIK refractive surgery or when we suspect the patient might have canaliculitis - an infection in the tear ducts characterized by yellowish secretions.
  2. Silicone (semi-permanent): These long-lasting plugs are suitable for chronic dry eye cases. Once inserted, these are often invisible to the naked eye due to their deep intracanalicular placement.

The Punctal Plug Procedure

Our eye doctor applies a local anesthetic to numb the area and places the plug into the tear duct opening. You won't feel more than a slight discomfort during the procedure. In fact, many patients report immediate relief from dry eye or excessive tearing symptoms.

However, it's essential to follow up with your eye care professional. Punctal plugs may occasionally cause dacryocystitis, a painful swelling due to tear duct blockages.

Possible Risks and Side Effects

Possible Risks and Side Effects

While punctal plugs have been proven to be a reliable solution for both dry eyes and excessive tearing, like all treatments and procedures, they come with a certain level of risk and potential side effects. Here, I've listed these in order of commonality and severity for your understanding.

Minor Side Effects

  1. Irritation: The most commonly experienced minor side effect is an irritating or scratchy feeling in the corner of your eyes where the plugs are. Most patients become accustomed to this feeling over time, or it subsides on its own.
  2. Excessive Tearing: The plugs may make your eyes overly watery with too many tears. If this happens, the plugs may need to be replaced with a different type or removed altogether.

Less Common, But Potential Side Effects

  1. Plug Movement: It's relatively uncommon, but possible for the plugs to move or fall out of the eyes, usually due to rubbing.
  2. Tear Duct Irritation: Punctal plugs can sometimes cause irritation of the tear ducts, leading to inflammation and swelling. If left untreated, this inflammation can result in damage to the tear ducts.

Rare Side Effects

  1. Improper Fit: If the plugs don't fit correctly, they can protrude from the tear ducts, causing irritation by rubbing against the eye or eyelid.
  2. Infections: Eye infections due to punctal plugs are rare. However, if they occur, prompt treatment will be necessary for the infection, and your doctor may decide to remove the plugs.

Should you experience any of these side effects after receiving your punctal plugs, we encourage you to immediately contact your eye care professional.

Which Patients Should Not Get Punctal Plugs?

Punctal plugs are not for everyone. Certain conditions can make it inadvisable to get them; your doctor will let you know if this is a case during your consultation.

Patients who have an active infection, issues with the drainage of the lacrimal system, or sensitivity to the material the plugs are made of, should not get punctal plugs. Additionally, if a patient has allergic conjunctivitis, punctal plugs should be avoided as they could result in allergens remaining on the ocular surface. Patients with severe blepharitis should also avoid punctal plugs.

When Are Punctal Plugs Removed, and What is the Process for That?

If certain serious side effects occur, your doctor may opt to remove your punctal plugs.

Most punctal plugs can be removed without surgery, by simply using forceps to pull them from the tear ducts or flushing them out with a saline solution.

Punctal plugs which were inserted deeper (inside the canaliculus) have to be surgically removed.

Common Questions

Absolutely, punctal plugs are a well-established treatment for dry eyes. By being inserted into the tear ducts, they slow down the drainage of tears, increasing eye surface moisture. This can significantly alleviate the symptoms of dry eyes, which include discomfort, burning, or itching. The effectiveness may vary from person to person, and it's always best to discuss your specific condition with our eye care professional before proceeding with this treatment.
The lifespan of punctal plugs in your eyes largely depends on the type used. Dissolvable plugs, usually made from collagen, are temporary and typically last a few days to weeks. Silicone plugs, on the other hand, are semi-permanent and can remain in the tear ducts for many months, and sometimes even years. However, the exact duration can vary depending on individual conditions and activities.
While punctal plugs are generally well-tolerated, there can be potential side effects. The most common is a slight discomfort or scratchy feeling in the corner of the eyes. This usually subsides over time. Rarely, plugs can cause excessive tearing, move out of position, or lead to infections or inflammation of the tear ducts. If you experience any side effects, it's recommended to contact our eye doctor immediately.
This depends on the severity of your dry eye condition. In some mild to moderate cases, punctal plugs alone can sufficiently alleviate dry eye symptoms. However, for more severe dry eyes, a combination of punctal plugs and lubricating eye drops may provide better relief. It's always best to follow the personalized treatment plan provided by our optometrist.
The insertion of punctal plugs is typically done under local anesthesia, meaning the procedure is painless. After the anesthetic wears off, you might experience slight discomfort, but this usually subsides quickly. Pain is not a typical side effect of punctal plugs. If you do experience pain, it's important to contact your eye care professional immediately.
Yes, you can. Punctal plugs do not inhibit the production of tears, they simply slow down the drainage. This means that emotional or reflexive crying is still entirely possible. However, because the tears drain more slowly, you might find that your tears stay on the surface of your eyes for longer.
Permanently getting rid of dry eyes depends on the underlying cause. It can involve lifestyle modifications, such as reducing screen time, improving diet, and staying hydrated. Medical treatments include lubricating eye drops, medications, and interventions like punctal plugs or even surgery in severe cases. As this is a complex issue, it's essential to consult with our eye care professional for a personalized treatment plan.
Punctal plugs can be either temporary or semi-permanent, depending on the type. Dissolvable plugs are temporary and last for a few days to weeks. Silicone plugs are semi-permanent and can stay in place for months or even years. In some cases, a doctor might opt for permanent closure of the tear ducts through a surgical procedure. This decision is usually made for chronic and severe dry eye cases.
