Patent ID: 7677728

Claim:
An ophthalmologic measuring apparatus comprising: an illuminating optical system including an illuminating light source to illuminate a subject eye; a light receiving optical system including a light receiving part to receive a reflected light flux from the subject eye illuminated with an illumination light flux of the illuminating optical system and to form a received light signal; a measurement part that, based on the received light signal formed by the light receiving part, measures a wavefront aberration at a predetermined measurement interval to obtain one-dimensional wavefront aberration data by Zernike coefficients, and obtains wavefront aberration data of a two-dimensional matrix form to represent a time course by grouping Zernike coefficients of each wavefront aberration of the subject eye in a blink interval from a blink to a next blink with respect to a first to an n-th (n is an integer of 2 or more) blink intervals; an analysis part that transforms the two-dimensional matrix to a new one-dimensional column vector with respect to the first to the n-th blink intervals measured by the measurement part, arranges a one-dimensional array of the wavefront aberration in a p-th (1≦p≦n) blink interval at a p-th column to create a two-dimensional matrix, and performs a principal component analysis processing on the two-dimensional matrix; and a display part to display a processing result of the analysis part.
