My doctor has recommended tear duct fusion, is it safe?

Hi I am a 50 year old female with severe dry eye problem. My eyes are always red and often ache. I use lubricant eye drops (Day and night versions) and manuka honey drops too. The drops have really helped. I also had plugs inserted into the tear ducts which also helps.

Now my eye doctor has suggested a more permanent solution – tear duct fusion. This will replace the need for plugs (they can fall out, get stuck etc.). However I can’t find any information about the procedure.

Can you please tell me how this works, possible side effects, recovery time?I’m due to have the procedure in a few days but I have so many questions and my doctor is in the public system so I can’t access her to ask.
