ABSTRACT:
A cornea laser-cutting apparatus adapted for use in cutting out a cornea of patient's or donor's eye in full thickness cornea transplanting surgery or keratoplasty. The cornea laser-cutting apparatus comprises an HF or Er-YAG laser source and a projection optical system for converging laser beams radiated from the laser source in a ring-like shape on the cornea, and includes an axicon lens or mirror movably mounted for varying the size of the ring-like shape.
