DCR Surgery: Procedure, Recovery and Results

External DCR

External DCR is performed through a small incision made on the side of the nose, close to the inner corner of the eye. This provides direct access to the tear sac and allows the surgeon to create a new connection between the tear drainage system and the nasal cavity.

Because the procedure involves a skin incision, a small external scar is possible. This is positioned discreetly and generally becomes less noticeable as it heals.

Endoscopic DCR

Endoscopic DCR is the preferred approach and is performed through the nasal passages using an endoscope, a small instrument equipped with a camera that allows the surgeon to view the treatment area from inside the nose.

The new drainage pathway is created internally, meaning there is no external skin incision or associated facial scar. As with external DCR, a temporary silicone tube may be used to support the new pathway during healing.

Which Type of DCR Surgery Is Right for Me?

Neither external nor endoscopic DCR is universally the better option. The most appropriate approach depends on factors such as your anatomy, the location and nature of the obstruction, previous procedures and your individual medical circumstances.

A specialist assessment of the tear drainage system is therefore necessary to determine the most suitable surgical approach for you. At the Ezra Clinic, we predominantly perform endoscopic DCR surgery.

How Successful Is DCR Surgery?

DCR surgery generally has a high success rate of approximately 95%  and can provide long-term improvement for patients whose watery eyes are caused by tear drainage obstruction. However, no surgical procedure can guarantee a successful outcome for every patient.

Results can be influenced by the location and cause of the blockage, individual anatomy, healing and whether previous tear drainage procedures have been performed. In some cases, the newly created drainage pathway can narrow or close during healing, causing watery eyes to persist or return.

If this occurs, further assessment may be required to determine whether additional treatment or revision surgery is appropriate.

FAQ

Is DCR surgery painful?

DCR surgery is performed under anaesthesia to minimise discomfort. Mild soreness, tenderness or pressure may occur during recovery and can usually be managed with appropriate pain relief.

How long does DCR surgery take?

DCR surgery typically takes about one to one and a half hours, although the exact duration varies depending on the surgical approach and the individual case.

Does DCR surgery leave a scar?

External DCR requires a small incision beside the nose and can leave a scar, although this usually fades over time. Endoscopic DCR is performed through the nose and does not require an external skin incision.

How long does it take to recover from DCR surgery?

Initial bruising and swelling usually improve during the first few weeks, although complete healing takes longer. Your surgeon will advise you when it is safe to return to exercise and other activities.

How long does a DCR tube stay in?

A temporary silicone tube may remain in place for several weeks while the new drainage pathway heals. The exact timing of removal depends on your procedure and recovery.

Can a blocked tear duct come back after the procedure?

Yes. Although DCR is generally successful, the new drainage pathway can occasionally narrow or close during healing, causing symptoms to return. These cases may require further treatment.
