Is there any new safe way to treat the conjunctiva nevus without leaving a scar? (Photo)

Dear Dr, I have a conjunctiva nevus since 20 years ago because some one hit me on my left eye with her finger,it makes my eye ugly, it looks like a pink mole with vessels on the white eye , my doctor told me it removes by excision and he used the scissors to cut it but this way will be a scar as he told me! so it's the worst than the nevus. My question is there any new way to treatment my eye with out a scar?
