dry eye disease
"I used restasis for several years and it worked.  My insurance stopped covering it which forced me to switch to xiidra which they do cover.  Xiidra doesn't work well and is very gooey.  Makes my vision blurry for up to an hour and irritates my sinuses due to the viscouness.   I think it's a placebo and a marketing scam.   Does not work well.  Insurance should stop practicing medicine."
