Eyelid surgery is performed using either local or general anaesthesia depending on the extent of cosmetic surgery.In the former, the skin around your eyes will be numbed using an injection. This is usually accompanied by some intravenous sedation to make you feel relaxed and insensitive to pain. Some people find the prospect of having an operation around the eyes under only local anaesthesia somewhat daunting. In these situations then a light general anaesthetic is probably best. In the case of a general anaesthetic you will be completely asleep. The type of anaesthetic suitable for you will be discussed at the time of the consultation. Whether the decision is for a local or a general anaesthetic, the operation is most commonly performed as a day case procedure.
