After canthotomy, we should pay attention to: ensure that the surgical site of canthotomy is clean to prevent infection; Try to avoid getting wet in the operating department within 7 days after opening the corner of the eye; After canthus surgery, local wounds can be bandaged with pressure or cold compress with ice packs, but the pressure should not be too high to avoid damaging the eyes. Once bleeding and severe hematoma appear after canthotomy, you should go to the hospital for follow-up in time; You should have a quiet and comfortable environment to recuperate after opening your eyes. Don't watch TV or newspaper within 2 weeks after operation, and stay in bed for half a day (raise the pillow) to avoid eye fatigue or bow your head and aggravate the swelling of the wound.
