These are the only drops that worked for me
I had a stem cell transplant almost four years ago and last year suffered dry eyes probably due in part to a late onset graft versus host reaction (my donor cells' antibodies attacking me) and Lasik surgery done a number of years ago.  I tried a host of other products which only seemed to lose effectiveness within minutes of application.  A neighbor recommended Thealoz Duo drops and I tried it.  It relieved symptoms for hours.  It is sterile from the bottle because it pours out of a filter which blocks bacteria from entering the bottle.  Anyway, it worked for me when all others didn't.  It is made in France, not sure why not in the U.S.  I use the Thealoz Gel at night which is great, but last batch came from the Ukraine and took forever and is expensive.  But again, it is the only nighttime gel that last throughout the night.
