Abstract
A corneal surgical apparatus for incising a cornea of a patient's eye in a layered form has a suction ring having an opening, which is vacuum-fixed to the patient's eye so that the cornea is projected from the opening. A cutting unit has a blade and an applanating member so that the cornea projected from the opening is incised by the blade while being applanated by the applanating member. A height changing mechanism is further provided, for changing a height of a tip of the blade in a visual axis direction of the patient's eye with respect to the suction ring.
