Cornea transplant

Q:

1. Is it permissible to undergo a cornea transplant? The cornea may be from a recently deceased registered tissue donor, or it could also be artificial.

2. If an artificial cornea isn't suitable/compatible and/or cannot be used, will it then be permissible to use from a donor?

Taking an animate picture out of necessity

Q: I heard that photos of animate objects are prohibited. Now I am preparing for a lawsuit against my landlord to get my rights back and the court needs evidence. I need a cleaning receipt to back my words but the receipt contains a human animate picture. This receipt is from a large cleaning company and can only be accessed online and I must take a screenshot (like photo). I heard under necessity haram things become permissible and to defend property is a necessity? Can I take the photo? If not I fear that my argument could be very weak and more injustice can be done to me as a tenant. 

Editing photo's of one's face

Q: Is editing your own photos haram? I mean I have moles on my face and I don't usually wear makeup to hide it... I edit my photos just to remove the dark circles and spots on my face. Is it haram? I don't make any change to my facial features. I just remove spots and dark circles.
