Abstract

The embodiment of the invention provides a method and a device for checking and fitting an orthokeratology lens. The method comprises the following steps: obtaining corneal topography data, wherein the corneal topography data comprise corneal eccentricity ratio and flat meridian refractive power; computing the diopter of a location arc of a cornea according to the corneal topography data and a preset correction value; computing the target diopter of a try-on orthokeratology lens according to the computed diopter of the location arc of the cornea and the corneal eccentricity ratio; outputting the target diopter, and reminding to select and try on a corresponding orthokeratology lens according to the target diopter. In such a way, the diopter suitable for the try-on orthokeratology lens canbe computed according to the corneal topography data, so that the checking and fitting accuracy of theorthokeratology lens is increased, and theoretical support is provided for checking and fitting oftheorthokeratology lens.

Description

technical field [0001] The invention relates to the field of orthokeratology fitting, in particular to a fitting method and device for orthokeratology. Background technique [0002] Orthokeratology is definitely effective in controlling the myopia of young people, and the development trend is good. However, orthokeratology is a relatively complicated optometry technology. Try on the lens, observe the result of the try-in lens, and then relax or tighten accordingly. However, this method mainly relies on the experience of the fitter and lacks theoretical support. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a fitting method and device for orthokeratology lenses, which can calculate the diopter of orthokeratology lenses suitable for try-on according to corneal topography data, and improve corneal orthokeratology. The accuracy of orthokeratology fitting provides th...
