Mole Removal Next to Eyes - how can I prevent keloids?

I have 2 moles on my face - one next to my eye, and one on my eyelid. My dermatologist cut out moles on my back several years ago and they turned into keloids. Even after several steroid shots, I still have a red bump on my back (larger than the original mole). Is it safe to remove the moles on my face, or can it also result in an incurable keloid scar? Also, is there any other less risky method of removing - like freezing?
