    I had LASIK surgery about 7 years back. My LASIK doctor put me on restasis right from the LASIK chair and it assisted my dry eye. He said my eyes would be better in 2 months and right at the 2 month mark, I was all much better. Nevertheless, 7 years later on… here I sit with severe dry eye from nothing else but LASIK.
