Results
When the visual functions were compared before and after the treatment, there was no significant difference found in the CDVA in both groups. In the N group, the FVA and VMR were significantly increased, however no significant change was found in both the FVA and VMR in the D group. In the D group, there were significant decreases in the Schirmer I test, BUT, and TMH, however the keratoconjunctival staining score increased significantly.

Baseline Characteristics
All patients were >20-years-of-age and were diagnosed with unilateral NLDO at the Ehime University Hospital. All of the patients were examined and treated by 3 ophthalmologists (TK, NT, AS). The diagnosis of a NLDO was based on the dye disappearance test, lacrimal irrigation, lacrimal cannula- tion, and dacryoendoscopic examinations. The subjects were treated by a new technique of dacryoendoscopic probing and sheath-guided bicanalicular intubation (SG-BCI), and none had any further treatment for the 6 months after the lacrimal stent removal. The cases that had a recurrence or were pre- scribed additional treatment were excluded.
Participant flow
All patients were treated with dacryoendoscopic probing, and the SG-BCI technique was used as described.5,11 Details of the probing and intubation are shown in Figure 1. This technique enabled surgeons to perform lacrimal passage reconstruction procedures under dacryoendoscopic observations without blind manipulation. After the intubation, all subjects were treated with topical 0.3% gatifloxacin and 0.1% fluorometholone 4 times/day, and a saline nasal lavage was applied regularly until the stent was removed. The stent was removed after 10-12 weeks.
