# What is the DCR procedure?

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
