Thanks for the replies. I will indeed give the hospital a call - good advice. Especially thanks to Wensleydale for the PM.
I can vouch for the fact that the Opthoms at CWL are rather special. I would, however, warn the unwary who are awaiting OASC that they are beautiful assasins. It seemed that most of those on my Part 2 medical got referred them to the eye specialist for one thing or another. Danger, danger.
