THANK YOU. I suspected that there might be a problem, but was unable
to locate anything with a warning about the use of Opcon A when there
is a dry eye diagnosis. Fortunately I took it only once.
My eye doctor gave me a bunch of different lubricants to try out. The
best of the lot, for me, are Soothe, Optive, and TheraTears. I don't
think any of them contain the preservative benzalkonium chloride.
Actually, the inactive ingredients in Restasis are fairly
soothing...have to look for an eye drop with castor oil, glycerin and
polysorbate.
