摘要

The present invention provides a morphology determining method of corneal topography, including: a parameter obtaining step, based on an original contour line of a cornea of a target subject as the reference, obtaining a relative displacement of each observation point of a contour line of the pressed cornea changed with time from the beginning of pressing the cornea by an external pressure to a predetermined time after the pressing is finished; a conversion step, performing a mathematical function conversion of the above relative displacement with respect to a spatial contour at each observation time point, so as to respectively obtain one or more order vibrational modes representing the contour line of the time points; and a determining step, respectively comparing the one or more order vibrational modes of the cornea of the target subject with a corresponding order vibrational mode of at least one reference cornea, and determining a morphology of the corneal topography of the cornea of the target subject.
