摘要：A method and device for identifying an angle on an eye of a patient. A methodfor identifying, on an eye of a patient, an operating angle measured in an angularreference mark (60) formed of the centre of the eye and a horizontal axis passingthrough the centre of the eye, said axis being within a horizontal plane (xt, yt) of areference mark of a predefined terrestrial reference frame (xt, yt, zt), consists of: formingan optical image of the eye on a planar sensitive surface (26) of a digital sensor (20), saidsensor being provided with a reference mark (x, y, z) comprising first and second axes (x,y) of said sensitive surface (26); acquiring a digital image of the optical image of the eyeformed on said sensitive surface (26), said image being provided with a reference markconsisting of first and second axes corresponding respectively to said first and secondaxes of the reference mark of the digital sensor; during the acquisition of the digitalimage of the eye, measuring the rotation of the reference mark (x, y, z) of the digitalsensor (20) relative to the reference mark (xt, yt, zt) of the terrestrial reference frame;defining a tilt angle (H) defined between the first axis (x) of the reference mark of thedigital sensor (20) and the intersection of the horizontal plane (xt, yt) of the referencemark (xt, yt, zt) of the terrestrial reference frame with the sensitive surface (26);

determining an angular reference mark (60) in the digital image of the eye, consisting ofthe digital image of the centre of the eye and an axis angularly separated from the firstaxis of the reference mark of the digital image by the defined tilt angle (H); transferringthe operating angle to the angular reference mark (60) of the digital image; anddisplaying the digital image of the eye with a mark (62) indicating the transferredoperating angle.
