The external CDCR group underwent routine dacryocystorhinostomy with partial carunculectomy. A tract was created from canthus to nasal cavity with von Graefe knife. In the laser CDCR group, the osteotomy was created using 980 mm diode laser with a power of 8 W. Glass tubes of appropriate length were placed and fixed using 5-0 polypropylene with our \"mirror tuck technique.\" Results were analyzed using the Chi-square test for parametric and ANOVA test for nonparametric variables using SPSS software.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>RESULTS:<\/jats:title>\n                    <jats:p>\n                      Success defined as patency on syringing was achieved in 18 patients in the laser group and 16 in the external CDCR group which was comparable (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &gt; 0.05).
