Most of the residents at my institution get very little experience with retina surgery, in comparison to anterior segment surgery. I assume retinal surgery is tougher because visualization is more difficult, but does it require more dexterity than, say, cataract surgery? Just wondering how people know they're cut out for retina (at least enough to apply for a VR fellowship) after only 2 years of ophtho residency, most of which is focused on anterior segment.
