Ophthalmic instrument having an integral wavefront sensor and display device that displays a graphical representation of high order aberrations of the human eye measured by the wavefront sensor

摘要

An improved ophthalmic instrument including an integral wavefront sensor and display device, wherein the wavefront sensor measures phase aberrations in reflections directed thereto to characterize aberrations of the eye and is operably coupled to the display device, which displays a graphical representation of the aberrations of the eye. Such graphical representation may include: two dimensional contour maps that graphically depict contribution of pre-specified terms (such as spherical aberration, astigmatism and coma) for the aberrations of the eye, coefficients corresponding to such pre-specified terms that characterize the aberrations of the eye, or predefined two-dimensional icons that provide a general graphical depiction of such prespecified terms. Such graphical representations provide the practitioner with valuable information characterizing the high order optical errors of the eye (which is far beyond the diopter information typically provided by current ophthalmic instruments) for use in diagnosis and treatment of abnormalities and disease in the eye.
