Abstract

Purpose To evaluate the efficacy of two-step retrograde closed stenting for treating canalicular laceration. Methods Forty-eight consecutive canalicular laceration cases (48 eyes) were randomised and divided into two groups: a one-step group and a two-step group. In the two-step group (23 cases), the first step was performed in the outpatient department and included identifying the medial cut end of the canaliculus and probing under a slit-lamp microscope, followed by a retrograde canalicular stenting assisted by a memory titanium stylet. The second step was canalicular anastomosis, which was performed in the operating room. In the one-step group (25 cases), all of the surgical procedures were performed when preoperative preparations were simultaneously available. Results The time elapsed from the doctor visit to the treatment was 4.3 +/- 2.4 h in the two-step group and 18.8 +/- 6.3 h in the onestep group (P<0.01). The canalicular medial cut ends were found in all cases, but 8.6 +/- 3.5 min was needed in the two-step group, and 51.4 +/- 24.2 min was needed in the one-step group (Po0.01). The numerical rating scale for pain during surgery was 1.8 +/- 1.2 in the two-step group and 5.4 +/- 2.2 in the one-step group (P<0.01). One case (2.63%) in the two-step group and nine cases (36%) in the one-step group required other assisted methods to locate the medial cut end (P = 0.007). Twenty-one cases (91.3%) in the two-step group and 20 cases (80%) in the one-step group achieved patent lacrimal drainage systems during Conclusions The two-step canalicular anastomosis method allows an early search for the medial cut end of the canaliculus and improves the chances of finding it; it is also a quicker, less invasive method for treating canalicular lacerations.
