Abstract

The invention discloses a suction pump type cornea molding sheet, which comprises an outer surface and an inner surface, wherein the inner surface is provided with a base arc, a reverse arc and a stable arc; when the user wears the cornea shaping sheet on the eyes, the base arc can generate pressing force on the eyes, the cornea on the eyes deforms towards the direction of the reversal arc due to the pressing, and the cornea shaping sheet can also slide to shape the cornea and cannot be injured when the cornea is contacted with the cornea due to the fact that the stabilizing arc is provided with at least one contact point to form a small suction force. The invention sucks the cornea to the positions of the base arc and the reversal arc through tear communication and suction force, and then the cornea is shaped according to the shape of the base arc. Therefore, after a user wears the suction pump type cornea molding sheet, the cornea can be effectively molded, and the aim and the effect of correcting the vision can be achieved.

Description

Suction pump type cornea molding sheet

Technical Field

The present invention relates to a corneal shaping technique, and more particularly to a suction pump type corneal shaping sheet for shaping a cornea by a suction pump technique.

Background

Corneal remodelling (OK) is a technique that gradually changes the shape of the cornea by systematically wearing a hard corneal remodelling piece to achieve a temporary change or removal of the refractive error.

Generally, the special design of the corneal plastic sheet can gradually change the shape of the corneal surface to a spherical radian, so as to achieve the effect of effectively reducing myopia and corneal astigmatism, so that a patient can enjoy comfortable and clear vision at any time after correction, but if the corneal plastic sheet is not worn for a long time, the cornea can return to the original shape.

Therefore, the prior art needs to continuously change the hard contact lenses during the correction period, i.e. the existing corneal plastic film must be worn for a long time to achieve the effect of correcting the vision.

In view of the above problems, it is an urgent need in the art to provide an improved cornea shaping method that can effectively and significantly shape a cornea and shorten the time required for shaping the cornea.

Disclosure of Invention

In order to solve the above-mentioned deficiency of corneal remodelling, an object of the present invention is to effectively remodel a cornea and shorten the corneal remodelling time, thereby achieving a significant vision correction.

In order to achieve the above object, the present invention provides a suction pump type corneal shaping sheet, comprising an outer surface and an inner surface; the method is characterized in that: the inner surface includes: the stable arc is arranged at the outer peripheral edge of the inner surface and is in an asymmetric shape; a base arc arranged at the position of the central periphery of the inner surface; and the inversion arc is arranged between the base arc and the stable arc of the inner surface, is symmetrical or asymmetrical, and forms a suction and pumping space between the base arc and the eyes.

When the base arc generates a pressing force on the eye, the cornea on the eye deforms towards the direction of the reverse arc and the base arc in the suction pump space, so that the cornea on the eye deforms in the suction pump space, and the cornea is shaped according to the shape of the base arc.

Because the stable arc is in an asymmetric shape and is matched with the asymmetric shape of the cornea, a slight suction force can be generated, so that the stable arc can be contacted with the cornea, but the cornea modeling sheet can also slide on the eye, and the cornea is not damaged.

Preferably, the stabilizing arc has at least one contact point that contacts the cornea such that a gap is formed between the stabilizing arc and the eye, thereby providing a small but non-limiting amount of suction force to allow the suction pump corneal shaping patch to be slidably worn on the eye.

Preferably, the shapes of the left and right or upper and lower of the inverted arc are symmetrical or asymmetrical to each other.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention. The invention is further illustrated below with reference to the drawings:

fig. 1 to 4 are a schematic structural diagram, a schematic usage state diagram, a schematic structural diagram after deformation of a base arc, and a schematic eye diagram after molding according to the present invention. As shown in fig. 1, the suction pump type corneal plastic molding plate 100 provided by the present invention comprises an outer surface 10 and an inner surface 20, and is characterized in that: the inner surface 20 defines a base arc 30, a counter-rotating arc 40, and a stabilizing arc 50.

Wherein the base curve 30 is disposed at a central peripheral position of the inner surface 20, when the user wears the suction pump type corneal plastic molding 100, the base curve 30 generates a pressing force to the user's eye 60, so that the eye 60 located at a position opposite to the base curve 30 is deformed.

The inversion arcs 40 are disposed between the base arcs 30 and the stabilization arcs 50 of the inner surface 20, the inversion arcs 40 on the left and right sides are symmetrical or asymmetrical, and a suction pump space SR is formed between the base arcs 30 and the inversion arcs 40 and the eye 60. When the eye 60 is deformed by the pressing force, the cornea 61 on the eye 60 is deformed in the direction toward the positions of the base arc 30 and the inversion arc 40 in the suction pump space SR, and the cornea 61 is shaped according to the shape of the base arc 30; at the same time, the epithelial fluid in the eye 60 located near the pressing force flows to a position away from the pressing force.

Stabilizing arc 50 is disposed on the outer periphery of inner surface 20, stabilizing arc 50 being asymmetrically shaped; when the base curve 30 presses the cornea 61 to deform the cornea 61, the cornea 61 located in the suction pump space SR corresponding to the base curve 30 is compressed and deformed inward, and the cornea 61 located in the suction pump space SR corresponding to the position of the reversed curve 40 and/or the base curve 30 is deformed to the position of the reversed curve 40 and/or the base curve 30, and the cornea 61 is shaped in accordance with the shape of the base curve 30.

The stabilizing arc 50 further functions to position the suction pump corneal mold 100 such that the suction pump corneal mold 100 can be accurately positioned onto the eye 60 and the inversion arc 40 can be positioned onto the cornea 61. Wherein the stable arc 50 is disposed on the outer periphery of the inner surface 20, the reversed arc 40 is disposed between the base arc 30 and the stable arc 50, when the stable arc 50 contacts the eye 60, the stable arc 50 has at least one contact point 51, the contact point 51 contacts with the cornea 61, so that a gap is formed between the stable arc 50 and the eye 60, thereby providing a small suction force without affecting the stability, so that the stable arc 50 can slidably contact with the eye 60, and the suction pump type corneal plastic film 100 is positioned and worn on the eye 60.

In addition, the stabilizing arcs 50 may assist the flow of epithelial fluid of the eye 60 in the direction of the inversion arcs 40 and/or the base arcs 30 to perform a remodelling treatment of the cornea 61.

In one embodiment, it is preferred that the stabilizing arc 50 have at least two contact points 51, each contact point 51 contacting the cornea 61, such that a gap is formed between the stabilizing arc 50 and the eye 60 between the contact points 51, providing a small suction force that does not affect stability, and allowing epithelial fluid of the eye 60 to flow toward a central location, making the cornea 61 more effective in sculpting.

According to the above structure, when the user wears the suction pump type corneal shaping piece 100 and the base curve 30 presses the eye 60 to deform the eye 60 inward, the cornea 61 is deformed toward the position direction of the inversion curve 40 and/or the base curve 30, and the cornea 61 of the eye 60 is shaped, so that the vision can be corrected.

Referring to fig. 5, a schematic diagram of the usage state of the asymmetric inverted arc 40 of the present invention is shown. The upper, lower, left, and right shapes of the reversed arcs 40 may be symmetrical or asymmetrical to each other, and in this embodiment, the reversed arcs 40 are formed by asymmetrical shapes. Thus, when the deformation is toward the position of the reverse arc 40 and/or the base arc 30, different molding states can be adjusted according to the left-right asymmetrical shape and different conditions of the user.

Referring to fig. 6A to 6C, there are shown schematic views illustrating the use of the pump-type corneal plastic strip 100 of the present invention in determining the wearing tightness. As shown, the tightness of the suction pump corneal molding 100 is evaluated according to the line of the stable arc 50. During assembly, the lubricant plus fluorescent agent and blue light are used to inspect tear communication and thickness, such as artificial tear 70 (colored tear) or other similar functional fluids.

As shown in FIG. 6A, when the suction-pump corneal shaping sheet 100 is too loose, the artificial tear 70 flows out from the loose place between the cornea 61 and the suction-pump corneal shaping sheet 100, and thus there is no suction when it is too loose; as shown in fig. 6B, if the suction pump type corneal shaping piece 100 is too tight in the over-tight state, the line of the outer peripheral stable arc 50 of the suction pump type corneal shaping piece 100 disappears at the over-tight position between the suction pump type corneal shaping piece 100 and the cornea 61, and the suction pump type corneal shaping piece 100 is not easily taken down when the outer peripheral stable arc is too tight; fig. 6C shows that two full circles should be formed between the suction pump corneal shaping plate 100 and the cornea 61 under the correct wearing condition. Therefore, only by correctly wearing the suction pump type corneal plastic molding sheet 100, the present invention can effectively achieve the desired effects of correcting eyesight, etc.

The detailed description is to be construed as specifically describing the embodiments of the present invention, but the embodiments are not to be construed as limiting the scope of the present invention, and all equivalent implementations or modifications that do not depart from the technical spirit of the present invention are intended to be included therein.
