Description

Intelligent inspection method and device for cornea shaping mirror based on digital dyeing

Technical Field

The invention relates to the technical field of cornea shaping mirrors, in particular to an intelligent inspection method and device of a cornea shaping mirror based on digital dyeing.

Background

The cornea shaping lens is made of a permeable hard cornea contact lens material, namely an ophthalmic lens made of RGP material, and RGP is an abbreviation of English Rigid Gas Permeable, namely a permeable hard material. It was developed on the basis of a hard material PMMA which is impermeable to gases. The "OK mirror" that is commonly seen in the market is actually a cornea shaping mirror. Cornea shaping glasses (OK Lens) are the most widely used optical means for controlling myopia progress clinically at present, have definite myopia control effect on myopic patients, can effectively slow down the eye axis growth of myopic patients, and compared with common frame glasses, the cornea shaping glasses have the control rate of 30% on the eye axis growth.

The special design of the cornea shaping lens can change the refraction of light rays by shaping the cornea so as to ensure that the light rays are correctly focused on the retina, thereby realizing the temporary myopia correction effect. Currently, the prescription of a cornea shaping lens is usually implemented by observing the fit relationship between the lens and the cornea under a slit lamp through dynamic fluorescence, and can also be implemented through a cornea topographic map. However, the traditional cornea shaping lens adaptation method mainly uses a specific light source capable of exciting fluorescein to observe the distribution of tears after a patient wears the cornea shaping lens and then dyes the cornea shaping lens through the fluorescein, so that the cornea shaping lens adaptation condition is judged. In addition, the use of fluorescein dye may interfere with the distribution of tears and may cause allergic reactions, dye residues, eye infection, corneal scratches, and other damage to the eyes of patients. It is important to provide a new way of matching the cornea shaping lens to improve the matching degree between the cornea shaping lens and the eyes of the user.
