I was watching a Discovery Channel documentary a while ago where they were showing an ancient Roman device, somewhat shaped like a hollow pencil, that was designed to remove cataracts from the human eye. The skill and precision of the instrument makers was incredible! But all things considered, if I had the option to have a magic spell do the same job, then I would much rather do that than have a pointy metal object jabbed into my eye.
What's the point of removing a cataract if you can't replace the lens of the eye? In modern cataract surgery they basically slide out the old messed up lens and replace it with one that works.
