    • The invention relates to an eye surgery apparatus (1) having imaging optics (14, 26, 27) for generating an observation image (40) of a patient's eye (16). The eye surgery apparatus (1) has a device (36) for determining the azimuthal orientation of a patient's eye (16) with respect to a reference (3) which is fixed with respect to the patient's eye (16). The device (36) contains a visual display device (34) for simultaneously displaying a section (92) of an observation image (40) of the patient's eye (16), which is captured by the imaging optics (14, 26, 27) and contains at least one segment of the limbus or of the iris, said section being composed of pixels, and a reference image of the patient's eye (16), which is composed of pixels (106) and contains this segment of the limbus or of the iris. The device (36) has an input interface (28) which makes it possible for an observer to move the displayed section (92) of the captured observation image (40) of the patient's eye (16) relative to the displayed section (94) of the reference image (80). The device (36) comprises a measuring system which can be used to determine the azimuthal orientation of the observation image and of the reference image, which orientation is changed during the relative movement. The device (36) has a computer unit (5) having a computer program for calculating the center (46) of the limbus (44) and/or of the iris (43) of the observation image (40) of the patient's eye (16), as captured by the imaging optics (14, 26, 27), and of the reference image (80). The visual display device (34) displays the pixels (102) of the observation image (40) of the patient's eye (16), as captured by the imaging optics (14, 26, 27), with polar coordinates in a polar coordinate system (96), the center (46) of which coincides with the calculated center of the circular structure (44) of the limbus and/or of the iris (43) of the patient's eye (16). It displays the pixels (106) of the reference image (80) of the patient's eye (16) with polar coordinates in a polar coordinate system (98), the center (84) of which corresponds to the calculated center of the circular structure (94) of the limbus of the patient's eye (16) on which the reference image (80) is based.
    • 眼科手术装置具有用于产生患者眼睛的观察图像的成像光学元件。 设备确定患者眼睛相对于相对于患者眼睛固定的基准的方位角取向。 该装置包括用于同时显示眼睛的观察图像的一部分的显示单元及其参考图像。 输入界面允许观察者相对于参考图像的显示部分移动观察图像的显示部分。 测量系统确定观察图像和参考图像的方位取向。 计算机程序计算观察图像和参考图像的角膜缘的中心。 显示单元以极坐标显示患者眼睛的观察图像的像素。 用极坐标显示患者眼睛的参考图像的像素。
