Diamond vs. Metal

Recently I participated in a debate about diamond versus metal for cataract surgery. When we enter the eye during cataract surgery, we can use metal or diamond instruments. Some people have pretty strong opinions on which is better. The summary is that diamond is sharper and cuts through faster, so it is very quick but can be dangerous because it can move along too fast. The metal cuts more slowly, which gives more control, but it requires more force and can sometimes not feel sharp enough. People have argued back and forth, but I think that, ultimately, it is up to each individual surgeon. Whatever is the safest a surgeon’s hands is what should be used. I personally feel better with metal, so that is what I use.
