Any success preventing erosions w/ amniotic membrane?

I am a weekly erosion sufferer, and have been for over a year.

I have followed all conventional wisdom, and have found taping my eyelids shut at night and using Muro 128 to be the best combination for healing fast.

Anyway, tomorrow I will go back to the doctor, and I think they said they would put an amniotic membrane on my eye if I was still having problems. Has anyone found that this helped prevent erosions?
