Abstract

The invention discloses a data processing method and related equipment based on orthokeratology lens fitting, and the method comprises the following steps: an obtaining step: obtaining instantaneous refractive power characteristic data of a to-be-measured cornea and to-be-measured eye measurement parameters of a patient; in the evaluation step, a cornea parameter map of the corrected cornea to be measured is simulated, and the cornea parameter map is generated according to the instantaneous refractive power characteristic data and the measurement parameters of the eye to be measured and used for predicting lens parameters matched with the eye to be measured; and an output step: extracting the corrected cornea parameter map data of the to-be-detected cornea, and outputting a fitting result according to a preset algorithm. And the trained model is used to accurately predict the glasses matching of the patient to be tested, so that the technical problems of low efficiency, large error and low reliability of the current glasses matching based on artificial experience are solved.

Description

technical field [0001] This application relates to the field of optician technology, in particular to a data processing method and related equipment based on orthokeratology optics. Background technique [0002] Orthokeratology lenses (OK lenses) are a special type of RGP lens. Ordinary RGP lenses (myopia lenses) are used to correct vision, while plastic lenses are used for "orthopedics", that is, to improve vision by changing the shape of the corneal assembly. "Corrective" type RGP lens, its inner surface is parallel to the surface of the cornea and coincides with each other, and the lens power is adjusted by changing the outer surface of the lens. The "orthopedic" plastic lens is the opposite. The outer surface is relatively simple, and the inner surface is relatively complex. The inner surface of the shaping lens is no longer parallel or consistent with the cornea, but some gaps are created between the lens and the cornea, and the effect of tear fluid is used to achiev...
