Abstract

A method and a device for evaluating the fitness of a corneal shaping lens are provided in the embodiments of the present invention, According to the refraction of each sampling point obtained from the corneal topography, the edge data points in each radial direction of the treatment area of the keratoplasty lens can be screened, the treatment area can be fitted according to the edge data points,and the fit state of the keratoplasty lens can be evaluated according to the eccentric distance. In this way, according to each data obtained from the corneal topography map, the analysis data of thefitness state of the corneal shaping lens can be obtained, the fitness state of the corneal shaping lens can be evaluated, and the evaluation error can be reduced by analyzing the specific data.

Description

technical field [0001] The invention relates to the technical field of medical artificial intelligence, in particular to a method and device for evaluating the fitting state of an orthokeratology lens. Background technique [0002] Wearing orthokeratology lenses is an effective treatment for myopia, reducing refractive errors by temporarily reshaping the anterior surface of the cornea with custom-made lenses. The specific principle is to change the shape of the cornea based on the oppressive effect of the lens, so that the central area of ​​the cornea is flatter and the peripheral area is steeper. However, in the process of using orthokeratology lenses to treat myopia, the center of the orthokeratology lens treatment area often deviates from the center of the pupil, which often causes high-order aberrations in the eyes of patients after use, which has a serious impact on vision. [0003] The traditional method for evaluating the fit status of orthokeratology lenses is to fi...
