I too had a 1.6 gram gold weight implanted 4 days after my AN surgery about 27 months ago. I also was able to have it removed this past Oct. after 2 yrs. My eye closes well now. I , however, was put to sleep for the surgeries ,, but they were relatively minor,, in comparison... I used ointment at night to help keep eye lubricated,, he will probably try many of the brands on the market before he decides which works best for him. I also used a lighter eye drop during the day to keep eye lubricated. My weight was pretty noticeable as it made my eyelid thicker and eye would not open completely ,, however, as Sara says protecting the eye and cornea is extremely important during paralysis..I also was very careful not to rub my eye..
I did not have any bruising nor did I have to use any ice packs after surgery..as it was so close to AN surgery,, it was the least of my worries,,,
,,,I did not have any problems this past Oct when it was removed either,, best of luck to him,, I feel sure he will do fine,,,keep us informed,, Jane
