Method for determining value of parameter representing aberration of eye of patient, for surgical system, involves determining particle accumulations in light pattern, and determining value of parameters from coordinates of accumulations

摘要

The method involves illuminating a cornea (9) of an eye (4) by a light device (6), and generating determined light images with certain geometric shape on the cornea. A light pattern of the light image is detected by a detector (3). Reflectance particle accumulations in the light pattern are determined and produced through the light device. Coordinates of the reflectance particle accumulations are determined, and value of parameters is determined from the coordinates of the reflectance particle accumulations, where the parameters are characterized by aberration of the eye. An independent claim is also included for a device for determining a value of a parameter representing aberration of an eye, for a surgical system.
