Embodiment 1

[0028] A soft orthokeratology pad, such as figure 2 As shown, there is an arc portion 1 opposite to the curvature direction of the cornea, and the end of the arc portion 1 away from the arc end (ie, the bottom end of the arc portion 1 ) extends with a cylindrical portion 2 . The orthokeratology cushion of this embodiment acts on the upper eyelid during use, presses the upper eyelid through the arc part 1, and the pressure added to the upper eyelid is transmitted to the cornea, thereby controlling the shortening of the eye axis, with low risk and comfortable wearing .

[0029] In this example, if figure 2 As shown, the arc portion 1 and the columnar portion 2 are both hollow structures. In order to facilitate connection with the heating bottom plate described later, a magnetic plate 201 is horizontally arranged in the cylindrical portion 2 along the radial direction, and the magnetic plate 201 may be an iron plate, a cobalt plate, a nickel plate or an alloy thereof.

Embodiment 2

[0032] An orthokeratology device, such as image 3 As shown, it includes a heating base plate and the orthokeratology soft pad in Embodiment 1, and the orthokeratology shaping soft pad is detachably connected with the heating base plate. Specifically, symmetrically distributed first orthokeratology cushions and second orthokeratology cushions are detachably connected to the heating base plate, and the distance between the centers of the first orthokeratology cushions and the second orthokeratology cushions is 7cm.

[0033] In this embodiment, in order to realize the detachable connection between the orthokeratology soft pad and the heating base, the heating base is provided with a magnet block 301, and the magnet block 301 is attracted to the magnetic plate 201 in the orthokeratology soft pad The corneal shaping soft pad is detachably connected with the heating base plate. Specifically, there are two magnet blocks 301, and their positions correspond to the positions of the f...

Abstract

The invention provides a cornea shaping cushion and a cornea shaping corrector, and belongs to the technical field of myopia correction. The cornea shaping cushion is provided with an arc part with the opposite curvature direction as the cornea, the end, away from the arc end, of the arc part extends to form a cylindrical part, the arc part and the cylindrical part are both of a hollow structure,wherein a magnetic plate is horizontally arranged inside the cylindrical part in the radial direction. The cornea shaping corrector comprises a heating base plate and a cornea shaping cushion. The heating base plate comprises a first shaping cotton cloth layer, a heating layer and a second shaping cotton cloth layer which are vertically stacked, wherein the heating layer comprises a graphene heating piece. Pressure applied to the palpebra superior through the cornea shaping cushion is transmitted to the cornea, and therefore the eye axis is controlled to be shortened; the graphene heating piece is arranged inside the heating base plate of the cornea shaping corrector, generated infrared rays heat and stimulates the eye skin muscle-nerve peripheral part, blood circulation of the eye peripheral acupuncture points is improved, and the correcting effect is improved.

Description

technical field [0001] The invention belongs to the technical field of myopia prevention and correction, and specifically relates to an orthokeratology cushion. In addition, the invention also relates to an orthokeratology device comprising the above-mentioned orthokeratology cushion. Background technique [0002] In 2018, the proportion of myopia among primary school students was 45.7%, that of junior high school students was 74.4%, that of high school students was 83.3%, and that of college students was 87.7%. This shows that the myopia prevention and control situation of children and adolescents in my country is very serious. At present, eye drops, laser therapy, and orthokeratology lenses are mostly used to prevent and control myopia. After using atropine eye drops, pupil dilation will occur for a long time, and long-term use will have sequelae; laser therapy is effective but also Recurrence; Orthokeratology lenses need to be configured in a professional eye hospital, wh...
