A nasal lacrimal stent is a medical device designed to treat nasolacrimal duct obstruction. This condition occurs when the tear ducts that drain tears from the eyes into the nose become blocked, causing tears to overflow and spill onto the cheeks. Nasal lacrimal stents are small, flexible silicone tubes that are placed into the tear ducts to keep them open and allow tears to flow normally into the nose.
The procedure to insert a nasal lacrimal stent is minimally invasive and is typically done under local anesthesia. During the procedure, the doctor will use a small instrument to insert the stent into the tear duct through the nostril. Once in place, the stent helps to bypass the obstruction and keep the tear duct open.

How Does a Nasal Lacrimal Stent Help Manage Nasolacrimal Duct Obstruction?
A nasal lacrimal stent helps manage nasolacrimal duct obstruction in several ways. By keeping the tear duct open, it allows tears to flow normally into the nose, preventing tears from overflowing and spilling onto the cheeks. This helps to reduce the discomfort and social embarrassment associated with excessive tearing. Additionally, by preventing the accumulation of stagnant tears, the stent reduces the risk of infections and inflammation in the tear ducts and surrounding tissues.
Benefits of Nasal Lacrimal Stent
Minimally invasive: The procedure to insert a nasal lacrimal stent is minimally invasive and is typically done under local anesthesia. This means that there is little to no pain, and recovery time is minimal.
Effective: Nasal lacrimal stents have a high success rate in managing nasolacrimal duct obstruction. Studies have shown that they are effective in relieving symptoms in over 90% of patients.
Customizable: Nasal lacrimal stents come in various sizes and shapes, making them customizable to fit the individual patient's anatomy. This ensures a comfortable fit and optimal tear drainage.
Long-lasting: Nasal lacrimal stents are designed to be long-lasting and can remain in place for several months to a year. This means that patients can enjoy relief from symptoms without needing frequent replacements.
Conclusion
Nasolacrimal duct obstruction can be a frustrating and uncomfortable condition to deal with. However, with the help of a nasal lacrimal stent, you can enjoy relief from excessive tearing and the associated discomfort. The stent is minimally invasive, highly effective, customizable, and long-lasting. If you are experiencing symptoms of nasolacrimal duct obstruction, consult with your eye doctor to determine if a nasal lacrimal stent is the right solution for you.
