Being a surgeon requires excellent vision. Some types of surgeons require more excellent vision than others. Microsurgeons such as ophthalmologists, neurosurgeons and vascular surgeons need particularly sharp vision. Know that people who have 20/25 or even 20/30 see very well, and in my opinion can function quite well as surgeons, again, depending on the visual demands. Orthopedic surgeons, for example, tend to work with larger instruments, and heavier sutures, which may allow for less than 20/20 vision. And, as time goes on, we are seeing more “robotic” surgery (ie DaVinci) in various fields, which will extend a mortal surgeons’ limited dexterity (and possibly vision) to superhuman levels.
