Abstract
The invention relates to an apparatus and a method for providing data for vision correction utilizing a volumetric ablation and an intrastromal manipulation. The provided data may be used by a laser ablating the surface of the cornea in combination with a laser which operates intrastromal to optimize a corneal re-shaping procedure. One aspects of the invention relates to the minimization of the amount of corneal tissue to be removed.
Claims17
A system for providing data for vision correction utilizing a volumetric ablation and an intrastromal manipulation, comprising:
- first computer software receiving diagnostic data representing a refractive error of a cornea of an eye;
- second computer software calculating at least one volumetric ablation profile based on said diagnostic data;
- third computer software calculating at least one intrastromal manipulation based on said diagnostic data;
- fourth computer software selecting at least one volumetric ablation profile and at least one intrastromal manipulation to optimize a combined treatment of a volumetric ablation and an intrastromal manipulation to correct said refractive error;
- wherein the intrastromal manipulation causes a bio-dynamic shape change of at least a portion of the cornea.
