Abstract

Purpose:

The purpose of this article is to describe a modified lacrimal bypass with a porous polyethylene-coated Jones tube.

Methods:

A total of 180 patients (180 eyes) with a nonreconstructable lacrimal obstruction underwent lacrimal bypass with a porous polyethylene-coated Jones tube through a retrocaruncular-middle meatus tract approach with endoscopic assistance. All patients were followed up at least for 24 months. Success rate of lacrimal bypass was analyzed and complications were recorded.

Results:

A total of 174 patients were finally included. Duration of surgery ranged from 28 to 47 minutes (mean 37.2 ± 4.2 minutes). The mean duration of follow-up was 30.0 ± 6.4 months (range 24–48 months). The mean tube length was 23.2 ± 1.9 mm (range 20–28 mm). At the final review, complete success was achieved in 138 (79.3%) patients. Moderate success was achieved in 23 (13.2%) patients, and 13 (7.5%) patients failed. Of the 161 patients successfully treated, 24 patients underwent revision surgery to excise granulomas (15 patients) or adjust tube position (9 patients). The complications included granuloma proliferation around the openings of the tube (28 eyes), downward displacement of the tube (17 eyes), and ocular discomfort (15 eyes). The majority of downward tube migration occurred in patients who had a prior history of dacryocystorhinostomy. The treatment failed for 5 patients because of repeated granulomas covering the nasal tube openings, and the treatment failed for 8 patients because of downward displacement of the tube.

Conclusions:

Our procedure appears to be an effective method for closed insertion of a porous polyethylene-coated Jones.
