My protocol is that, if the surgery is under straight local anesthesia, pretesting is not required unless a patient's medical conditions are such that I feel it is appropriate. However, whenever anesthesia, whether intravenous sedation or general is used, pretesting and medical clearance are the appropriate standard of care.
Depending on the type of anesthesia and the condition of your health, a physical exam and blood test may be requested. This is most often the case for surgery requiring general anesthesia. Generally for eyelid surgery, it can be done under local anesthesia without a need for these tests.
