Dacryocystorhinostomy (DCR) is a tear duct bypass operation that restores drainage from the tear sac into the nose when the nasolacrimal duct is blocked. It treats persistent watery eyes and recurrent tear sac infections.
What Happens During DCR?
In external DCR, a small incision is made beside the nose, bone over the tear sac is opened, and a new passage is created into the nasal cavity. In endoscopic DCR, similar steps are performed through the nostril using a camera, usually without a skin incision.
- Soft silicone tubes are often placed temporarily to keep the new channel open
- The operation is carried out under local anaesthetic with sedation or general anaesthetic
- Sutures and the small scar from external DCR usually heal well
- Both approaches have high success rates when the underlying obstruction is suitable
Recovery and Aftercare
After DCR, bruising, swelling, nasal stuffiness, and mild bleeding are common for a short period. Nasal sprays, saline rinses, and eye drops help healing and reduce blockage risk.
- Patients are advised to avoid heavy lifting, nose blowing, and swimming initially
- Follow-up visits check tube position and the patency of the new passage
- Most people notice a marked reduction in watering once healing is complete
- Occasionally revision surgery is needed if scarring closes the opening
