I have NF2 and have experienced eye issues on both sides.
After my first AN was removed, although I had no facial paralysis, the amount of tears my eye produced decreased dramatically. I got a punctum plug that solved my problems well.
During my last AN surgery in April, my facial nerved snapped due to some complications that I had. The ends were patched together with surgical adhesive as my doctors did not want to take the time to stitch them together.
I think that I have some nerve function since the exterior of my face feels normal. However, the inside of my mouth is numb.
I got a gold weight and my lower lid was tightened. This helped tremendously. The period of time after I was released from the hospital and before my eye surgery was tough. I used drops every 15 minutes and had quite a buildup on my lashes. I picked the dried lubricant off my lashes and that mostly worked. I also held my eye closed in the shower and let the water run on my face for a while. This too helped. One time, however, I was cleaning up the gunk using the first method when I accidently pulled a big clump of lashes out. That solved the problem for a while but it hurt for a while too.
I consider myself fortunate now as my need for lubrication has declined greatly. It is Sunday afternoon and I have only put drops in once this weekend in addition to using my normal nightly lubricant. And, my vision has really benefitted from using less drops. I have even begun to read again!
Best wishes to you all,
Jeff
