Purpose

To evaluate the efficacy of a minimally invasive punctum-preserving canaliculotomy combined with RS-type silicone tube (RS tube) intubation for treating primary chronic canaliculitis (primary chronic canaliculitis).

Methods

This retrospective study included 62 patients (62 eyes) with primary chronic canaliculitis who underwent the procedure between October 2020 and September 2022.

n = 62 patients
Results

checked at 12 months, tear-duct passages stayed open and unblocked in nearly all eyes

98.2%
Anatomic success
94.5%
Functional success
More results

All surgeries were completed within 30 minutes under local anesthesia, with successful tube placement in all cases.

At 12 months, all patients exhibited resolved inflammation with no recurrences.

Functional success was 94.5% (52/55), with 2 patients reporting occasional epiphora despite patent irrigation.

More results

No procedural complications occurred.

“
Conclusion · 1 of 2

Minimally invasive punctum-preserving canaliculotomy with RS tube intubation is a safe and effective treatment for primary chronic canaliculitis, yielding high anatomic and functional success rates.

Conclusion · 2 of 2

These results suggest it is a promising alternative to conventional techniques, though larger prospective trials are needed to validate its efficacy.
