30 year old scar on eyelid and temple; what are my options? (Photos)

My scar was caused by a car accident when I was 8yrs old. I hate looking in the mirror and am so sick of people asking me how it happened. The eyelid tissue is puffy and loose and eyebrow is longer than the other side. Do I have any options and any estimates as to the range of costs I would be looking at? I am desperate to be normal again, please help.
