Abstract:
An eye surgery system for shaping the cornea of the eye, comprising:a laser that emits a light beam having a propagation axis; an optical system cooperating with the laser that directs the light beam to the cornea forming a light spot on a surface of the cornea, wherein the propagation axis of the light beam at the cornea locates the position of the light spot on the corneal surface; and a control unit in cooperation with the optical system that controls a light spot sizing component of the optical system to create a selectively variable size of the light spot on the corneal surface and a propagation axis directing component of the optical system for locating the beam spot at a selective plurality of locations on the corneal surface, wherein the control unit regulates the size of the light spot in correlation to the selective directing of the beam propagation axis.
