Surgery of tear ducts

Individuals with persistent tearing, recurrent eye infections, or swelling near the inner corner of the eye may be candidates for tear duct surgery. The candidacy is determined based on the underlying cause of tear duct obstruction, such as congenital abnormalities, scarring, or inflammation.

Before tear duct surgery, the doctor will perform a comprehensive eye examination to assess the condition of the tear ducts and confirm the diagnosis. Preoperative preparation may include: Evaluation of medical history and current medications. Imaging studies such as dacryocystography or nasal endoscopy to visualize the tear ducts and identify the site of obstruction. Discussion of the surgical procedure, potential risks, and expected outcomes. Instructions regarding fasting before surgery and any medications to be avoided.

The surgical procedure typically involves the following steps: Anesthesia: Local or general anesthesia is administered to ensure the patient's comfort during the procedure. Incision: The surgeon creates a small incision near the inner corner of the eye or inside the nasal cavity to access the blocked tear duct. Creation of a new pathway: The surgeon creates a connection between the tear sac and the nasal cavity by removing the obstructed portion of the tear duct and placing a stent or silicone tube to maintain the new opening. Closure: The incision site is closed with sutures, and nasal packing may be used to minimize bleeding and promote healing.

The outcomes of tear duct surgery are generally favorable, with many patients experiencing improvement in symptoms such as tearing, eye infections, and swelling. The success of the procedure depends on factors such as the underlying cause of tear duct obstruction and the skill of the surgeon.

After surgery, patients should follow postoperative instructions provided by the surgeon, including proper wound care, use of prescribed medications, and activity restrictions. Regular follow-up appointments are essential to monitor healing, evaluate the function of the tear ducts, and remove any stents or tubes placed during surgery. Patients should avoid activities that may increase the risk of injury to the surgical site, such as rubbing or touching the eyes, blowing the nose forcefully, or engaging in strenuous physical activities. Any signs of infection, excessive bleeding, or worsening symptoms should be reported to the doctor promptly for further evaluation and management.
