**DCT (Dacryocystectomy)** is a surgical procedure involving the complete removal of the **lacrimal sac (tear sac)**. Unlike DCR, which attempts to restore tear drainage, DCT eliminates the sac entirely. This procedure is chosen primarily when the tear sac is chronically infected and inflamed (**dacryocystitis**), and when the primary solution, DCR, is not advisable.
DCT is performed to eliminate a source of persistent infection and prevent it from spreading to the orbit or surrounding tissues. While it resolves the infection, patients should be aware that it results in permanent, chronic **watery eyes (epiphora)**, as the tears can no longer drain naturally into the nose.
Removes the chronically infected tear sac to prevent serious, potentially sight-threatening complications.
Ideal for patients who are too frail for a longer DCR procedure or have specific nasal/sinus contraindications.
Typically performed through a small, cosmetic incision on the side of the nose (External Dacryocystectomy).
While infection is resolved, patients are counselled that chronic tearing will remain, managed with wiping.
