Monocanalicular and bicanalicular silicone tube intubation results in patients with congenital nasolacrimal duct obstruction

Methods: A total of 47 eyes of 42 patients – 25 females; 17 males – on whom silicone tube intubation was performed due to congenital nasolacrimal duct obstruction (CLDO) were involved in the study. As part of the study, a monocanalicular tube was placed in 23 of the 47 eyes (1st group), while a bicanalicular tube was placed in 24 of the eyes (2nd group). The average age in the first group was 6.13 years (1–15 years) and 4.51 years (1–15 years) in the second group. Extubation was performed in the postoperative 4.2 month (2–7 months) in the first group and in the postoperative 4.4 month (2–7 months) in the second group. Average length of follow-up of cases was determined to be 10.1 months (6–72 months).
