Abstract
A corneal surgical apparatus, which can smoothly incise the cornea (particularly the Bowman's membrane at the cutting start) while ensuring the cutting ability of the blade with a simple arrangement. After a suction unit is fixed to a periphery of the cornea of patient's eye, the cornea projecting from an opening portion provided in the suction unit is applanated substantially flatly, and the applanated cornea is incised in a layered form by a blade. The blade is moved such that any point on the blade depicts an arcuate locus of the same shape.
