Eyelid surgery, also called blepharoplasty, whether aesthetic or medical, takes place in conditions of optimal comfort and safety for patients. Most generally upper eyelid surgery is done under local anesthesia. This consists, after the application of an anesthetic cream, of injecting local anesthesia directly into the eyelids. This allows an operation without any pain. When this is necessary, additional sedation is offered in order to allow, in addition to the pain-relieving action of anesthesia, a relaxing action of sedation. For the lower eyelids, sedation is more frequent because the interventions can be slightly more painful and longer, allowing you an optimal level of comfort. Finally, if associated procedures such as lipofilling or lipostructure are planned, general anesthesia is often recommended.
