Thanks everyone for all the advice

.
I now have the minims and the redness is almost gone

. I managed to get an emergency appointment at the hospital and all they concluded was that I was allergic to the preservative - tell me something I didn't know

! Anyway the good news is that my vision is back to 'normal'. I recall that on the previous occassion I was given both the drops and the ointment and the effect was agonising

so I will only be using the minims from now on - whatever the cost to my GP

! I am feeling much happier now and really appreciate everyones help, it's good to have such a knowledgeable group to talk to when there is a problem
