Blocked Tearduct Surgery
During DCR (dacryocystorhinostomy) surgery a direct opening is created between the tear sac and the nose, bypassing the blocked nasolacrimal duct. The procedure is either performed via a small skin incision on the sidewall of the nose, an "External DCR", or trans-nasally, an "Endoscopic DCR." Both procedures are routinely performed in a day surgery on an outpatient basis.
Endoscopic DCR is routinely performed under general anaesthesia. The operative time for both techniques is approximately 45 minutes.
At the time of surgery a fine silicone stent is placed and then removed 3 weeks post-op in the rooms. Occasionally this prolapses spontaneously requiring an extra visit to the rooms for early removal.
