Title: Ophthalmic device
Inventor: UMEKAWA KAZUAKI
IPC: A61B3/10
Filed: 2000-03-27
Abstract: PROBLEM TO BE SOLVED: To precisely obtain the refractive power of an eye and the radius of curvature of the cornea. SOLUTION: For obtaining the eye refractive power of an examined eye E, an eye refractive power measuring light source projects a spot image onto the examined eye fundus, a ring stop and a conical prism shape the reflected light into a ring, and an image pickup element 18 picks up the ring image R, which is subjected to elliptic approximation. The picked-up image data are transferred to an image memory that stores it. The process of elliptic approximation forms coordinates in a horizontal direction H and a vertical direction V in accordance with the pixels, and determines the center of the two-dimensional coordinates as (Hc, Vc). Data on perpendicular lines to long sides of masks a1 and a2 and others in other directions are used in center-of-gravity calculation, and the method of least squares is used in elliptic approximation.  From the ellipse thus obtained, measured values are determined including the refractive power, astigmatism and astigmatism axis angle of the examined eye.
