This prospective clinical study evaluates the efficacy of a simplified canaliculo-dacryocystorhinostomy (canaliculo-DCR) procedure for treating epiphora caused by common canalicular obstruction. Conducted at the Regional Institute of Ophthalmology (RIO) in Guwahati, this research serves as a benchmark for surgical success in the North East Indian population.
Study Methodology
The study analyzed 100 patients (ages 21–60) with a focus on a modified, single-flap technique performed under local anesthesia. A key inclusion criterion was a patent canaliculus length of at least 8 mm.
Success Metrics
- Overall Success: 78% acceptable outcome rate.
- Complete Resolution: 56% total disappearance of symptoms.
- Partial Success: 22% significant improvement.

The simplified technique involves anastomosing only the anterior flaps, significantly reducing operative time.
The Physiological Advantage
Unlike standard DCR, Canaliculo-DCR is the preferred physiological reconstruction for blocks located in the small drainage channels. By utilizing a single-flap anastomosis, the procedure is made easier and less time-consuming without compromising the encouraging success rates.
Clinical Takeaway
The modified canaliculo-DCR is a successful and standard operative procedure for managing common canalicular blocks. While it requires high-grade technical skills in micro-dissection, it offers a superior alternative to less satisfactory medical or surgical treatments in the regional demographic.
Surgical FAQ
Silicone tubes remain in place for six months to ensure the new passage stays open. Most patients return to normal activities within a few days post-surgery.
Minor complications may include nasal irritation or infection (22%), both of which are manageable with standard post-operative care.
