GenTeal drops with GenAqua

[Susan]

I was looking at these drops and it says they contain a preservative that turns into pure water and oxygen upon contact with your eye.

Has anyone used these? Are they ok to use 1 month post lasik?

The "preservative-free on contact" artifical tears may be an improvement over artifical tears with preservatives, but the true preservative-free drops are the least likely to cause a problematic response.

When in doubt, go preservative-free, but this is something that you need to check with your doctor.
