[0002] Ophthalmic surgery is a very delicate technique that does not allow for the slightest error. Ophthalmic surgery is usually performed under a microscope. The patient lies on the operating table with the head fixed with a bandage to expose the eye to be operated on. The surgeon sits on a chair and bends over the patient to perform the surgery. The ophthalmic operating tables used in various hospitals are basically flat-bed operating tables. In order to facilitate the doctor's operation, the patient's head is not placed directly on the operating table, but on an additional combined or non-combined head frame. This gives the surgeon ample space and is conducive to the operation.
