Has anyone's dc had procedure to unblock tear duct?

[puffling]

DD who's 20 months is having tear duct unblocked under general anaesthetic tomorrow.
Will she be uncomfortable afterwards?

dd1 is almost 16 now but she had it done twice around the age of 2

she was fine afterwards, there wasnt really anything to see

75% of probings worked first time then, 95% on hte second attempt

i dont know what the rate is now but she hasnt had any problems since

Thanks Lou33.
