In Star Wars, how many characters have cybernetic enhancements?
In The Empire Strikes Back, Luke has his severed hand replaced shortly after losing it.
Anakin also has most of his arm replaced in Attack of the Clones; later, he becomes more machine than man with cybernetics.
Commander Wolffe also gets a cybernetic eye.
General Grievous has most of his body replaced by cybernetics. However, his organs still appear mostly intact.
The technology seems to perfectly replicate the mechanics of a human hand/arm/eye/cardiovascular system/respiratory system/skin.
Would it be considered a common medical practice to replace lost/damaged body parts with Cybernetics? Or Were these procedures considered available to only elite characters?
At first it seems fairly common however the three characters mentioned above may be considered special enough to have an uncommon medical procedure executed:
Luke: Hero of the Rebel Alliance to Restore the Republic, leader of Rouge/Red Squadron, Friends with Princess/General Leia Organa.
Anakin: Jedi Knight at the height of their power during a war with a nearly blank check policy.
Darth Vader: Sith Lord during tyrannical rule of Sith Empire. Apprentice to said Empire's leader.
Commander Wolf: Commander with some skill over the standard trooper. He also had a personal relationship with Jedi Master Plo Koon, who may have more pull to help out Wolf.
General Grievous: Second in command to the Separatist Army. A tool to be used by Darth Sidious and en elite warrior in his own right.
