It would be good if you could wait this crisis out lulu, but if you absolutely have to break the fast then just make sure you do it carefully with small portions of raw fruits. Give your body plenty of time to adjust back to digestion mode from ketosis and that will give your body the best chance to complete whatever detox or healing process that the fast has begun regarding your eyes. We all need to be careful at all times when breaking a medium to long term fast but this is even more important during a crisis when the body is already working it's hardest focussing on that one part of your body.
