@sue225 I also find Xiidra to be a better medication. To stop the stinging just keep the vials in the refrigerator. I also find that I get two doses out of one vial pretty easily. And finally, please do not scrape the vial edge across your eye. I tore my cornea and it was a pretty painful experience.

Sometimes I forget to read the pamphlet that comes with a medication so I miss the warnings. Good luck with doing it the right way. You would think I might know better at this age.

Be safe and protected from inner and outer harm.
