Keratoconjunctivitis Sicca
"I have an extreme dry left eye that drives me crazy for about 2 years can&#039;t wait to get home to wash my eye at night  the right eye is dry per my dr exam but not nearly as bad.  First few days in bad eye felt better off the bat.  I am a sceptic so it really did feel better.  1 month later my really dry left eye feels wonderful.  I was going to use it only in left bad eye due to the cost but once I opened the vial saw how much was in there I decided to use in against drs orders though  I wash my hands and do not touch the dropper at all.  works great for me"
