Praise God! Surgery was a success!
Our surgeon said that placing the stints was no easy task this time, and that he had to make incisions to open both nasolacrimal ducts enough to get the stints in. He said that the tear ducts were very tight from scarring, but that he was able to get them in.
Typically, nasolacrimal duct stints are left in for three to four months. The surgeon said that we will leave these stints in indefinitely. The last set was left in for six months, and were removed this past September. Apparently, that was long enough, because here we are again.
He's watching cartoons until the nurse can release us.
