Well, there are lots of stats if you dig down into the evidence given in the NICE guidelines on CXL
www.nice.org.uk/IPG466, some of which Dan Gore quoted in the talk he gave at a London group meeting back in 2012. But you're right, we'll have to invite him back again to give us the up to date stats from the Moorfields experience so far. The general figure quoted is, I think, around 3% of negative results. So low risk, though that's not much comfort for those in the 3%.
We're all still crossing our fingers that your haze will clear eventually, Olly.
