When I went to Honduras a few months ago, I was taught to use an
auto-refractor machine to look inside eyes and get a prescription for
glasses. I loved the job because every eye was different with beautiful
patterns just like those in the photos. I tried to take photos through the
refractor but just got interference lines. When I photographed cataract
surgery several years ago, I used a Leica R6.2 with the 100 Macro. It did
a great job but I also had lots of light from the operating room lights.
Good luck!
