It's looking promising, thanks. The gas bubble is still present but only covering about one fifth of the eye. I tried some modelling, but when I look down through the gas bubble I lose focus and 3D vision so it wasn't very successful. However, I have high hopes that it won't be too long before I'm up and running again as above the bubble vision is quickly returning to normal. Not quite there yet but still it's early days.
When they did my cataract I was over the moon that I could start using my camera properly again. Today, I gave that a go too. If I dial in the biggest correction available into the viewfinder then I managed that quite well, although I was relying on its autofocus which fortunately is very good. Again as it is still early days and things should improve I'm happy with the way things are going.
