Patent AT-E400240-T1: [Translated] SURGICAL APPARATUS FOR MINIMIZING ASTIGMATISM, MEASURED TOPOGRAPHICALLY AND REFRACTIVELY
A method of surgically treating an eye of a patient to correct astigmatism in which values of astigmatism are measured topographically and refractively, and limit values of targeted induced astigmatism for the topographically and refractively measured astigmatism values are obtained by summating the topographically value of astigmatism with the refractive value of astigmatism and vice versa. Respective target values of astigmatism for refraction and topography based on the limit values are obtained and surgical treatment is effected with a target induced astigmatism which is intermediate the limit values and provided respective topographical and refractive non-zero target astigmatism values whose sum is a minimum.
