Hi, welcome to the forum, there seems to be mucopurulent drainage
from the puncta occurs when there is bacterial growth in the stagnant tear
pool of the lacrimal sac called as acute dacryocystitis. It also present with erythema, swelling, warmth, and/or tenderness of the lacrimal sac. There seems to be secondary complication of the surgery.
This needs to be treated with topical antibiotics.
