The suction ring has an opening from which the cornea of the patient's eye is projected. An applanating portion is provided, which has a flat side abutting against the cornea of the patient eye projected from the opening of the suction ring. A blade is supported movably along said suction ring in a space defined between the suction ring and the flat side of the applanating portion. A projection is associated with the blade to increase the space as the blade incises the cornea.
