Patent ID: 7380942

Claim:
A method for measuring the wave aberrations of the eye, based on probing the eye with a narrow laser beam, detection of the radiation scattered by the retina, measurement of the wave front tilt in the form of the first partial derivatives along the coordinates in a discrete set of pupil points with known coordinates, approximation of the wave front in the form of functions of pupil coordinates using data from the detection of radiation scattered by the retina, and calculation of wave aberrations of the eye as deformations of the approximated wave front, characterized in that the partial derivatives at any pupil point are determined by means of spline approximation using the values in a discrete set of points, where the wave front tilts are measured, that are located along concentric circles with a common center which coincides with the center of coordinates, wherein the approximation of partial derivatives at the beginning is performed along each concentric circle and then along radii to the pupil points and the wave front is reconstructed by means of the numerical integration.
