There are two main types of DCR: external and endonasal. The external DCR is the gold standard procedure and the most preferred to treat primary acquired NLD obstruction (NLDO), with a reported success rate that reaches up to 97%.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>AIM:<\/jats:title>\n                    <jats:p>This retrospective cohort study was carried out to assess the functional and anatomical success rates of DCR done at a tertiary eye care hospital between 2017 and 2023, determined by patency on syringing and\/or negative fluorescein dye disappearance test, and Munk\u2019s score of zero to one.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>MATERIALS AND METHODS:<\/jats:title>\n                    <jats:p>Clinical records of five hundred and one patients who underwent DCR surgery between 2017 and 2023 were reviewed, of which a hundred and seventy-seven records were included in this study.
