Types of punctal plugs

  1. Silicone punctal plugs: These plugs are made from a soft, flexible silicone material and are the most commonly used type of punctal plug. They are available in different shapes and sizes to fit the individual needs of the patient. They can be easily inserted into the tear duct by an eye care professional and can remain in place for several months to several years. Some of the benefits of silicone punctal plugs include their long-lasting effect, low cost, and ease of insertion. However, they may sometimes irritate the eye or cause tearing.
  2. Collagen punctal plugs: These plugs are made from a natural, absorbable material that is derived from animal sources. They are typically used as a temporary solution for patients who have mild to moderate dry eye symptoms. Collagen plugs slowly dissolve over time, typically lasting from a few days to a few weeks. They are often used as a diagnostic tool to determine if punctal occlusion is an effective treatment option for a patient. Some of the benefits of collagen plugs include their biocompatibility and their ability to be easily inserted and removed.
  3. Hydrogel punctal plugs: These plugs are made from a hydrogel material that can absorb water and expand, creating a seal in the tear duct. Hydrogel plugs can help patients experiencing severe dry eye symptoms because they provide a longer-lasting effect than other types of plugs. They can remain in place for several months, but may cause irritation and discomfort in some patients. They are typically more expensive than silicone plugs, but may be a good option for patients with more severe symptoms.
  4. Self-retaining punctal plugs: These plugs are designed with a unique shape that allows them to stay in place without the need for adhesives or sutures. They are typically used for patients who have a history of punctal plug displacement. Self-retaining plugs are made from a variety of materials, including silicone and hydrogel. Some of the benefits of self-retaining plugs include their ability to stay in place for longer periods of time and their reduced risk of being lost or displaced.

How Are They Inserted?

It’s simple. Your doctor can do it in the office. The doctor will numb your tear duct and then push in the plug with forceps. The doctor may need to expand the duct opening with a tool called a lacrimal dilator. This may feel a bit strange, but it is not painful and only takes a few minutes.

The plugs come in various shapes, sizes, and colors. Your doctor will determine the best fit for you.

Punctal Eyeplugs side effects

While punctal plugs are generally safe, there are some risks associated with the procedure.

One of the most common risks is discomfort or irritation in the eye after the plug has been inserted. This can be caused by the presence of a foreign object in the eye or by the plug being too large for the punctum. In some cases, the plug may need to be removed if the discomfort persists.

Another potential risk is infection. Although rare, infection can occur if the insertion site is not properly sterilized or if the plug itself becomes contaminated. Symptoms of infection include redness, swelling, pain, and discharge from the eye. If you experience any of these symptoms, it’s important to contact your eye doctor immediately.

Punctal plugs can sometimes also cause excessive tearing or watery eyes. This occurs when the plug causes too much moisture to be retained in the eye, leading to overflow and tears running down the face. This side effect is usually temporary and will resolve on its own as the eye adjusts to the plug.

It’s important to note that punctal plugs may not be suitable for everyone. People with certain eye conditions, such as glaucoma or a history of eye infections, may not be good candidates for the procedure. Overall, the choice of punctal plug type will depend on the individual needs and symptoms of the patient. Your eye care professional can help you determine which type of punctal plug is right for you and provide guidance on how to use and care for your plugs.
