As an ophthalmologist myself I can assure everyone that orbis is a very worthwhile cause. Their mission is to train local ophthalmologists to be able to treat their patients rather than have foreigners return year after year- making it sustainable for locals.

There are teaching microscopes and actually lecture rooms for local docs to learn from visiting docs.

I’ve never participated in orbis myself but know two friends that have. They said it was well worth their time. I’ve also heard the director of orbis give a talk at a ophthalmology society conference. Very impressed at what they do.
