What Is DCT Surgery?
DCT surgery, or Dacryocystectomy, is a procedure that helps restore normal tear drainage. When the tear duct gets blocked, tears cannot flow as they should. As a result, eyes may water often or become infected. DCT surgery removes the blocked tear sac, helping to stop these problems. Many eye doctors, called ophthalmologists, offer this surgery in clinics and hospitals around the world.
Who Needs DCT Surgery?
Not everyone with watery eyes needs DCT surgery. However, some people do benefit from it. Usually, doctors suggest this surgery when other treatments do not work. For example, if you have a long-term tear duct blockage or repeated infections, DCT surgery may help. In some cases, people with a painful swelling near the nose also need this procedure.
Symptoms of Tear Drainage Problems
Blocked tear ducts can cause many symptoms. Often, these signs are easy to notice. For instance, you may see tears running down your face even when you are not crying. Sometimes, the eye feels sticky or looks red. In addition, some people notice pain or swelling near the nose.
Causes of Tear Drainage Blockage
Many things can block the tear drainage system. Sometimes, the cause is an infection. Other times, an injury or aging can narrow the tear duct. In rare cases, growths or tumors may block the pathway. Because of these reasons, it is important to see an eye doctor for the right diagnosis.
How DCT Surgery Works
DCT surgery removes the tear sac that is blocked. This stops the buildup of fluid and infection. During the procedure, the surgeon makes a small cut near the inner corner of the eye. Next, the blocked sac is taken out. Because the tear sac is removed, tears will not collect and cause infection.
Although DCT surgery does not restore tear flow, it prevents further problems. For many people, this means fewer infections and less discomfort. Eye specialists use safe and proven methods, as recommended by trusted sources like the American Academy of Ophthalmology.
Diagnosis Before DCT Surgery
Before DCT surgery, doctors need to confirm the blockage. Usually, they start with a simple eye exam. Sometimes, they use special tests to check tear flow. For example, a dye test can show if tears drain as they should. In some cases, imaging tests like X-rays or scans help find the exact spot of the blockage.
What to Expect During the Procedure
On the day of DCT surgery, you will meet with your surgical team. First, they will clean the area and give you medicine to numb the skin. Sometimes, doctors use light sedation to help you relax. Then, the surgeon makes a small cut near the nose and removes the blocked sac. The skin is closed with stitches. Most people go home the same day.
Recovery and Aftercare
After DCT surgery, you may notice mild swelling or bruising. However, these symptoms usually improve within a week. Your doctor will give you instructions for care at home. For instance, you may need to use antibiotic drops or ointment. It is important to keep the area clean and avoid rubbing your eye.
Risks and Possible Complications
Like any surgery, DCT surgery has some risks. Most people recover well, but problems can happen. For example, infection or bleeding may occur. In rare cases, there may be scarring or changes in skin appearance. Because of these risks, it is important to choose a skilled eye surgeon. According to the American Academy of Ophthalmology, serious complications are rare.
Tips for Healthy Eyes After Surgery
Taking care of your eyes after DCT surgery helps with healing. For best results, follow your doctor’s advice. In addition, you can protect your eyes by practicing good hygiene. If you notice any new symptoms, contact your eye care team right away.
Preventing Tear Drainage Issues
While some tear drainage problems cannot be avoided, you can lower your risk. For example, treat eye infections early and avoid eye injuries. In addition, regular eye check-ups help find problems before they get worse. In many regions, eye care services offer advice on keeping your eyes healthy.
