An operating table for ophthalmic surgery consisting of a base, held at an adequate height from the floor by supporting members, and on which a stretcher is placed which is movable in the longitudinal sense and adjustable in height, one end of which is connected to an adjustable assembly comprising a first device for positioning the patient's head, with the body being on said stretcher, in the position most convenient for carrying out the surgical operation and a second device supporting a mask element provided with an opening in which the eye to be operated on is adapted and on the edge of which the orbital edge of said eye is sealed. A transparent rigid airtight cover is provided which may be adapted on said base plane in such a way as to create an airtight environment apt to be appropriately depressurized through conventional vacuum means, said airtight environment completely surrounding the body of the patient with the exception of the eye to be operated on, which through said opening in said mask element appears exposed to the pressure of the outside ambient. |
