How do I fix Serana's yellow eye problem?

After I had Serana cure herself of vampirism, she came back as a very useful character: I can heal her, she’s invincible and she still uses her health drain powers. However, her eyes totally creep me out: she has the green irises but the “whites” are glowing yellow at me. It’s like she has nuclear jaundice.

How can I fix her eyes to something more sensible? Human eyes are preferable (green + white) but at this point, I’m looking for anything that’s less creepy.
