Hi Mona: I've got 2 options for you regarding sleeping at night, (since you need to be adding moisture to your eye at all times to prevent corneal ulcers),
1. the inexpensive (but a pain in the butt - I did it for over 1 year): make a square of saran wrap to go just over your eyebrow & below your eye & tape all four sides (I apply a cotton ball with alcohol around the area to be taped & let it dry to give a great adhesion - you're making a moisture chamber).
Or, if you can afford it (in this economic crisis),
2. you can buy NITEYE, The Dry Eye Comforter, at approx. $21.00 per 14 nonsterile pack. (I'm lucky enough to be able to buy it by the case & save over $100. I know I'll need to use them the rest of my life). Again, I apply alcohol with a cotton ball around the area to come in contact with the adhesive.
Their phone # is: 1-800-874-5797; they'll walk you through the process for ordering.
I'm hoping you already have a gold/platinum eye weight in your upper lid to help with blinking.
I never had a nerve graft after the AN surgery, but I did have the T3 (Temporalis Tendon Transfer) at Johns Hopkins, Baltimore Maryland, with Dr. Patrick Byrne - he is a pioneer in this surgery for people with facial paralysis & no chance of nerve regeneration. I had this surgery done just shy of 1 1/2 years after the AN surgery. It's the best thing I did for myself - you can also look into this option.
Most people have a nerve graft with great results - I was too chicken to have my nerves operated on again (it's just my neurosis).
Also, I have just learned that for eye symmetry, you need to go to an experienced oculoplastic surgeon - they are THE BEST for giving your eye the best appearance possible !
There are pictures of my before/after T3 at Facial Issues: Post Temporalis Tendon Transfer, on pages 2 & 4.
Always good thoughts, Nancy
