I have never heard of a MD that would do such a damaging thing, I would first suggest you seek professional assistance and try to make your eye duct normal again!
I make the Dr. Christopher eye wash formula and eye syrup herbal formula. The eye wash is the most powerful thing I know of to restore function to an eye along with all the clean ups as listed in the free 108 page booklet.
In the mean time I would suggest your own home made distilled water and maybe just a touch of real salt and strain this very well and use as an eye wash, when your ducts are repaired, then you can use herbs, it would be no use to aid ducts that have been sewed up.
