Punctal plugs are a proven solution for dry eye, enhancing eye comfort by improving tear retention. Our experienced eye doctors can help you find the best type for your needs.
Punctal plugs are tiny devices that address the discomfort caused by dry eye by blocking or slowing tear drainage. They are especially important for patients who struggle with chronic dry eye symptoms such as irritation, redness, and a gritty sensation. Our eye doctors carefully consider these plugs as part of a broader approach to help preserve tear film for improved comfort and better overall ocular health.
Punctal plugs come in several types, including silicone, collagen, and intracanalicular plugs. Each type is tailored to specific needs ranging from short-term trial therapy to more long-lasting relief. With a range of design innovations and materials, these devices aim to fit naturally within the tear drainage system and improve treatment outcomes for patients suffering from dry eye.
At its most basic level, a punctal plug is inserted into the punctum, the small opening on the edge of your eyelid that normally drains tears away. By partially or completely blocking tear drainage, the natural lubrication on the ocular surface is maintained for a longer period. Here’s the thing: more tears retained on the surface mean less discomfort, reduced irritation, and a more stable tear film.
When additional treatments, like artificial tears or prescription medications, are used in conjunction with punctal plugs, their effects can be further amplified. The plugs essentially serve as a support system, making every drop of tear or medication count toward improved eye comfort and overall health.
Silicone plugs have been a mainstay for many years. Made from medical-grade silicone, these plugs are designed for long-term use. Their durability and reliable design ensure that they remain in place for extended periods, effectively reducing the rate of tear drainage. However, they can sometimes cause a foreign body sensation or, in rare cases, lead to complications such as pyogenic granuloma. Our eye doctors carefully balance these factors by evaluating both the benefits and potential risks of silicone plugs on an individual basis.
Recent innovations have led to new designs such as the Soft Plug Extended Duration 180-T. This plug is slightly larger than traditional silicone plugs, with a bulk diameter at 0.6 mm and a tapered tip that measures 0.25 mm. This modification enables the plug to fit more naturally into the punctal opening, reducing insertion complications and alleviating patient discomfort.
Collagen plugs offer a temporary solution for patients who are testing the benefits of punctal occlusion. Made from an absorbable protein material, they are designed to dissolve naturally within days or weeks. This temporary nature makes them an excellent “trial run” for patients who and their eye care team want to determine if blocking tear drainage can significantly improve dry eye symptoms.
Because collagen plugs dissolve over time, they eliminate the need for a removal procedure. They are particularly useful following procedures that cause temporary dry eye or during seasonal episodes of dry eye symptoms. The natural absorbable quality means that if a patient responds well, our eye doctors can then consider moving to a more durable option later on.
Unlike plugs placed directly at the punctal opening, intracanalicular plugs are inserted deeper into the canaliculus, the channel that carries tears away from the eye. Once in place, these plugs are typically not visible, making them a discreet option for patients who may be concerned about the appearance of a plug on their eyelid.
Innovative materials like thermodynamic acrylic polymers (SmartPlugs) or hydrogels (such as the Oasis FormFit plug) are among the newer generations of intracanalicular plugs. These versions adapt to the shape of the canaliculus or slightly expand once they hydrate, ensuring a comfortable fit that maximizes tear retention while minimizing the risk of migration or displacement.

Recent design improvements in punctal plugs have focused on tailoring the shape and size of the plug to match the natural anatomy of the punctum. The traditional cylindrical designs often did not meet the diverse shapes of punctal openings, potentially leading to complications during insertion and an increased risk of the plug falling out. To address these issues, our eye doctors now have access to plugs featuring a tapered edge and a wider range of sizes.
For example, the Soft Plug Extended Duration 180-T incorporates a tapered tip that eases insertion into the often oval or linear punctal opening. Because the tip is only 0.25 mm wide—while the bulk of the plug measures 0.6 mm—more tears are effectively occluded within the canaliculus, and the chance of the plug being dislodged is lower. This enhanced design contributes to improved comfort and better overall outcomes, with patient acceptance rates being notably higher.
Another advantage of this innovative design is that it minimizes the amount of time our eye doctors spend determining the exact size required. Since the plug functions as a nearly one-size-fits-all device, with minor adjustments for particularly small punctal openings possibly requiring gentle dilation, treatment becomes smoother and more efficient. The enhanced design also reduces the sensation of having a foreign body in the eye, which is often a reported concern with older plug models.
Before punctal plug insertion, our eye doctors will evaluate your tear film and the anatomy of your tear drainage system. This comprehensive exam ensures that the correct type and size of plug is chosen to maximize tear retention and alleviate dry eye symptoms. A few basic measurements, such as tear break-up time and punctal size, help guide the decision-making process.
The process starts with numbing the area using a topical anesthetic. This step helps minimize any potential discomfort during the insertion. In addition, lubricants are applied to aid the smooth placement of the plug into the punctum.
Once the eye is properly prepared, the insertion of the punctal plug is straightforward. Our eye doctors typically follow these steps:
It is important to note that while the procedure is quick and typically painless, a slight pressure or tug is sometimes felt during insertion. If any discomfort persists afterward, our eye doctors are ready to assess the situation and make any necessary adjustments.
