What kind of local anaesthesia is usually used for doing blepharoplasty? And what kind of oral sedation or IV sedation is used?

I am guessing that this may vary among doctors, however, in general - what are the pharmaceutical names of the local anaesthesia usually used for doing lower blepharoplasty? For instance, is Xylocaine a common one and why? How is it different from Lidocaine? And what kind of commonly used oral sedation (e.g. Valium) and IV sedation are used, including Twilight anaesthesia?
