Look into all possible remedies including dietary supplements like flax and fish oil and punctul plugs,
restasis, and also look very closely
for lid margin disease. Secondly, I'm ver surprised that botox didn't help and it makes me wonder how much experience that doc has with botox for that problem. Suggest you see oculoplastic surgeon who has experience in botox for blepharospasm. In the end it may be a combination of all 3 problems.
