Which preservative may I find in which eye drops?

We made this chart to facilitate your research based on reports than we have received so far. However, please always read the insert from the package of the eye drop or the gel/ointment in any case to confirm that the mentioned preservative is still used (remember that the same drop may exist in without preservative, unfortunately that's seldom the case). We only mention dry eye (and wound healing), glaucoma and allergy drops in this chart.
