Brief summary
Single dose tranexamic acid (TA) before dacryocystorhinostomy (DCR) operation: a prospective, double blind, placebo controlled study. The study hypothesis: TA in DCR might reduce the intraoperative and postoperative bleeding in DCR surgery, and might reduce the duration of the surgery.
Interventions

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Duration of DCR surgery in minutes and amount of blood loss in milliliters during surgery. | Blood loss will be measured at the end of DCR operation from the suction bowel. Duration of surgery will be caculated by registering time of operation start and end. |
