Intelligent evaluation auxiliary system and method for orthokeratology lens

Abstract

The invention discloses an intelligent evaluation auxiliary system and method for an orthokeratology lens. The system comprises a parameter obtaining module which is used for obtaining the lens matching parameters and basic features of a patient; a corneal topographic map database used for storing corneal difference topographic maps before and after lens fitting; a marking module used for presetting marks of a real area and a central point in the cornea difference topographic map; a model building module used for building an orthokeratology lens evaluation auxiliary model according to the lens matching parameters, the basic features and the cornea difference topographic map of the patient and the real treatment area and the mark of the center point; and a model evaluation module used for evaluating the orthokeratology evaluation auxiliary model according to a preset evaluation index and outputting an evaluation result. According to the system and the method, an orthokeratology lens fitting basis can be provided, and a doctor or a photosist can quickly and accurately provide a lens fitting processing opinion according to the lens fitting basis, so that the lens fitting accuracy is ensured, and the lens fitting efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of orthokeratology lenses, in particular to an intelligent evaluation auxiliary system and method for orthokeratology lenses. Background technique [0002] Orthokeratology lenses originated in the United States. They are rigid corneal contact lenses similar to contact lenses. Wearing them during sleep at night can flatten the central corneal curvature and steepen the peripheral areas. It can not only correct the refractive state of the central retina, At the same time, it can correct the hyperopic defocus of the peripheral retina, so as to effectively control the development of myopia in children. [0003] At present, the way of fitting orthokeratology lenses is that the doctor or optometrist manually conducts multiple try-in and fitting evaluations on the user to determine the best orthokeratology lens parameters, and then performs orthokeratology lens fitting. Customization and processing. However, this ...

Problems solved by technology

However, this method is more due to the personal fitting technology and experience of doctors or optometrists, and it is not accurate enough and not efficient enough for patients who need glasses.
