An artificial intelligence-guided system for corneal cross-linking

Abstract

An artificial intelligence guiding system for cornea crosslinking comprises the components of an ocular surface dispersed light image acquisition system which is configured for acquire a user ocular surface dispersed light image and sufficiently reflects cornea information; a cornea topographical map generating system which is pre-trained for converting the ocular surface dispersed light image toa corresponding cornea topographical map; a cornea crosslinking guiding system which is pre-trained for outputting a parameter required for a crosslinking surgery through comparison between a before-crosslinking cornea topographical map and an expected postoperative cornea topographical map; an ocular surface dispersed light image and corresponding cornea topographical map database which is used for storing an image pair of the ocular surface dispersed light image and the cornea topographical map and is used for pre-training a model and continuously correcting the model; and a cornea topographical map and cornea crosslinking parameter corresponding database which is used for recording the influence of the cornea crosslinking parameter to the cornea topographical map and performs a re-correcting function on the crosslinking guiding system. The artificial intelligence guiding system can greatly improve efficiency, accuracy and stability in a cornea crosslinking surgery process and reduces errors caused by subjective determining of a doctor.

Description

technical field [0001] The invention relates to an ophthalmic medical device, in particular to an artificial intelligence guidance system for corneal cross-linking. Background technique [0002] The cornea is a transparent tissue at the front of the eyeball and plays an important role in the eyeball optical system. Its refractive power accounts for more than half of the eyeball's refractive system. A slight change in the shape of the cornea can cause a large change in vision. Keratoconus is an ocular disease in which the cornea is dilated and the center thins and protrudes forward, making the cornea appear conical in shape. It changes the shape of the cornea in a large range and causes a sharp decline in vision. Myopia, hyperopia and astigmatism are all ophthalmic diseases involving the refractive power of the eyeball system. By changing the refractive power of the cornea, the disease can be alleviated and the effect of restoring vision can be achieved. [0003] Corneal cro...

Problems solved by technology

[0005] The main purpose of the present invention is to solve the problem that existing corneal cross-linking instruments rely too much on the subjective judgment of users, and provide an intelligent system for corneal cross-linking, which can provide clear assistance to instrument users and significantly improve corneal cross-linking.
