Embodiment 1

[0033] figure 1 It is a perspective view of the corneal protector 10 according to Embodiment 1 of the present invention; figure 2 It is a side view of the corneal protector 10 according to Embodiment 1 of the present invention. Such as figure 1 with figure 2 As shown, the corneal protector 10 includes a light blocking ring 1 that can be placed between the eyelid and the white of the eye and matched with the eye. The central area of ​​the light-blocking ring 1 has a transmission hole 2 with a diameter of 7-9 mm that can be opposite to the eyeball. Wherein, the material of the light blocking ring 1 is different transparent hard materials, such as resin or metal. In a preferred embodiment, the material of the light blocking ring 1 is polymethyl methacrylate, so as to avoid adverse reactions of users.

Abstract

The invention relates to a cornea protector and a placing and taking tool suitable for the same. The cornea protector comprises a shading ring which can be placed between the eyelid and the white of the eye and make matched contact with the eye. A transmission hole which can be opposite to the eyeball and has a diameter of 7-9 mm is formed in the center of the shading ring, and the shading ring is 0.15-0.25 mm thick, 19-27mm long and 19-21 mm wide. The cornea protector can effectively protect the corneal stroma, limbal stem cells and endothelial cells of the non-treated part in the corneal collagen crosslinking process. People can place or take the cornea protector conveniently through the placing and taking tool suitable for the cornea protector.

Description

technical field [0001] The invention relates to a corneal protector and a removal tool suitable for the corneal protector. Background technique [0002] Corneal collagen cross-linking treatment is to use ultraviolet light with a wavelength of 370 nanometers to activate riboflavin (photosensitizer) and convert it into reactive oxygen species, which then induce chemical reactions between amino groups of corneal collagen fibers in the treatment site. The cross-linking reaction can increase the diameter of corneal collagen fibers, improve the resistance of corneal stroma to various degrading enzymes and other biological effects, thereby increasing the mechanical strength of corneal stroma. [0003] However, during the corneal collagen cross-linking process, the patient's eyeball may move, causing the ultraviolet rays to move from the treatment site to the non-treatment site, thereby damaging the corneal stroma, limbal stem cells, and endothelial cells in the non-treatment site. ...
