Nose surgery

Q: I have a very wide nose. Whenever I look at my nose I feel stressed and low confidence when meeting with people. My intention is not to look beautiful but I just want to get confidence. Can I undergo nose surgery to make my nose little smaller.

Looking at a diagram of the eye

Q: I have a few questions about the eye and pictures. 

If one is studying how the eye functions and its diseases, is it permissible for one to view the eye? If a diagram of the inner eye is drawn, should one erase it, or is it not necessary considering its not the outer eye part?

Can a woman become an ophthalmologist to treat only females to avoid other females going to male ophthalmologists?
