Intelligent topographic corneal procedure advisor

A computer program product for generating a cylinder compensation and a spherical compensation for a corneal surgical procedure on an eye wherein the computer program product including a readable storage medium that is not a transitory signal per se, the program product including instructions executable by one or more processors to cause the one or more processors to perform a method comprising:

• determining a topographic vector from a topographic corneal map of the eye, the topographic vector indicating a magnitude and a direction of an optical effect of a corneal talus, wherein the topographic corneal map is determined by a topographic-based LASIK treatment system including an optical measurement device;
• determining a posterior astigmatism vector and an anterior astigmatism vector for the eye;
• generating an interior astigmatism vector using the topographic vector, the posterior astigmatism vector, the anterior astigmatism vector, and a manifest astigmatism vector;
• generating the cylinder compensation of a treatment recommendation using the interior astigmatism vector and the posterior astigmatism vector;
• and
• generating the spherical compensation of the treatment recommendation using an initial spherical compensation modified by a topographic addback modifier and a cylinder addback modifier, where the topographic addback modifier is a value indicating a refractive effect of a difference between a height of a highest talus and an amount of tissue to be removed from the center of the cornea, and where the cylinder addback modifier is a value of one half a difference between a magnitude of the manifest astigmatism vector and a magnitude of the cylinder compensation;
• and
• generating instructions executable by an excimer laser to perform a treatment based on the treatment recommendation, the cylinder compensation, and the spherical compensation.

A system for generating improved treatment recommendations for corneal procedures on an eye, the system comprising:

• a display;
• a processor;
• and
• a computer readable storage medium having program instructions embodied therewith, wherein the computer readable storage medium is not a transitory signal per se, the program instructions executable by the processor to cause the processor to:
• receive a topographic corneal map, a posterior astigmatism vector, an anterior astigmatism vector, an initial spherical compensation, an initial set of cylinder compensation values, and a manifest astigmatism vector for the eye;
• determine a topographic vector from the topographic corneal map of the eye;
• generate an interior astigmatism vector using the topographic vector, the posterior astigmatism vector, the anterior astigmatism vector, and the manifest astigmatism vector;
• generate a cylinder compensation for the initial set of cylinder compensation values using the interior astigmatism vector and the posterior astigmatism vector;
• generate a spherical compensation for the initial spherical compensation using the initial spherical compensation modified by a topographic addback modifier and a cylinder addback modifier;
• and
• output, to the display, a visual representation of a treatment recommendation including the cylinder compensation and the spherical compensation;
• and
• generating instructions executable by an excimer laser to perform a treatment based on the treatment recommendation, the cylinder compensation, and the spherical compensation.
