Abstract

The present invention can effectively double the therapeutic effect by effectively absorbing the heat generated from the injured cornea in the case where the cornea is damaged by an external factor such as a nail or a surgical operation such as LASIK or LASEK, The present invention relates to a refrigerant built-in contact lens capable of providing a cool feeling of coolness.
The present invention relates to a contact lens with a built-in refrigerant, comprising: a contact lens body which is worn on a cornea and in which an accommodation space is formed; and a coolant filled in a housing space of the contact lens body, .

Description

[0001] CONTACT LENS FILLED WITH REFRIGRANT [0002]

The present invention relates to a contact lens to be worn on the entire surface of an eyeball, mainly a cornea, for therapeutic purposes.

Contact lenses are commonly used on the entire surface of the eye, mainly for correction of cornea or for the purpose of cosmetics, but they are also used for therapeutic purposes in addition to vision correction or cosmetic purposes.

Such a therapeutic contact lens is formed to cover the damaged cornea so that the damaged cornea is blocked from the outside, thereby preventing the recovery action of the cornea from being hindered by interference of external factors.

That is, when the epithelium of the corneal surface is damaged by an external factor such as a nail or a surgical operation such as LASIK or LASEK, the epithelium is restored after a predetermined time like skin, When the injured epithelium and the eyelid are in contact with each other or when the dust is penetrated into the injured epithelium, the recovery of the epithelium becomes difficult or the epithelial recovery time is significantly delayed. Therefore, if the damaged cornea is covered with the therapeutic contact lens, the damaged cornea can be recovered without interfering with external factors.

An example of such a therapeutic contact lens is disclosed in Korean Patent Registration No. 10-0708446 (registered on Apr. 10, 2007), and includes a central portion provided to cover the central side of the cornea and a central portion provided around the central portion to cover the outer side of the cornea Wherein the curvature of the inner surface of the rim is greater than the curvature of the rim of the rim of the rim of the corners of the cornea, Wherein a curvature of the inner surface of the central portion is smaller than a curvature of the cornea of the central portion so that the cornea of the damaged portion is quickly pressed while being pressed inside the eyeball by the central portion, A cornea of various wearers having different curvatures is provided so as to be close to a flat surface so that the cornea can be commonly pressed A therapeutic contact lens characterized by the following:

However, in the case of the conventional treatment contact lens as described above, only the action of covering and pressing the wearer's cornea is provided, and the heat generated from the injured cornea can not be sufficiently dissipated, There is a problem that a cooling sensation can not be provided to the user.

SUMMARY OF THE INVENTION The present invention has been conceived to overcome the problems of the prior art described above, and it is an object of the present invention to provide a method and apparatus for effectively removing heat generated from an injured cornea in a case where the cornea is damaged by an external factor such as a nail or a surgical operation such as LASIK or LASEK The present invention provides a contact lens with a built-in refrigerant, which can provide a cool sensation to a wearer as well as a treatment effect can be doubled.

It is an object of the present invention to provide a contact lens apparatus which comprises a contact lens body which is worn on a cornea and in which a housing space is formed and a coolant filled in a housing space of the contact lens body and providing a cold feeling when the contact lens body is worn This is achieved by providing a contact lens with a built-in refrigerant.

According to a preferred feature of the present invention, the refrigerant is distilled water or physiological saline.

According to a preferred aspect of the present invention, the contact lens body filled with the refrigerant is refrigerated until it is worn on the cornea.

The refrigerant-containing contact lens according to the present invention is a refrigerant-containing type contact lens according to the present invention, in which a refrigerant for providing a cool feeling is accommodated in a housing space of a contact lens body, When the cornea is worn on the damaged cornea due to an enemy factor, the heat generated from the cornea damaged by the cold sensation transmitted from the coolant is effectively absorbed, thereby doubling the therapeutic effect and providing a cool sensation to the wearer. .

1 is a perspective view of a refrigerant-embedded contact lens according to an embodiment of the present invention;
2 is a sectional view of a refrigerant-embedded contact lens according to an embodiment of the present invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. , And this does not mean that the technical idea and scope of the present invention are limited.

The coolant-containing contact lens 1 according to an embodiment of the present invention is applied to corneal images damaged by external factors such as fingernails or surgical factors such as LASIK or LASEK procedures, And a cooling sensation is provided to the wearer. As shown in FIGS. 1 and 2, the cornea is worn by the cornea, and a receiving space 11 is provided inside the cornea And a refrigerant 20 filled in the accommodation space 11 of the contact lens body 10 and providing a cool feeling when the contact lens body 10 is worn.

Here, the contact lens body 10 corresponds to a hard contact lens or a soft contact lens to be worn on the cornea, and includes a conventional contact lens and a soft contact lens, The detailed description will be omitted here for the sake of simplification of the description.

However, it is preferable that the contact lens body 10 is formed of a disposable soft contact lens so as to be easier to mold than a hard contact lens and to be suitable for a corneal treatment assistant.

The refrigerant 20 is filled in the accommodation space 11 of the contact lens body 10. The coolant 20 provides a cool feeling when the contact lens body 10 is worn, 10, it is preferable that the lens is formed of distilled water or physiological saline which is harmless to the eye even if it is leaked due to breakage of the contact lens body 10.

The refrigerant 20 is injected into the accommodation space 11 of the contact lens body 10 by the syringe and then embedded in the accommodation space 11 of the contact lens body 10 as the needle penetrated through the needle of the syringe And various other possible methods can be applied.

The contact lens body 10 filled with the refrigerant 20 is preferably stored in the refrigerator until it is worn on the cornea, so that the cooling effect by the refrigerant can be maximized.

As described above, the refrigerant-containing contact lens 1 according to the present invention is in a state in which the refrigerant is stored in the refrigerated state until just before wearing, because the refrigerant 20, which provides a cold feeling in the accommodation space 11 of the contact lens body 10, The heat generated from the cornea damaged by the cold sensation transmitted from the refrigerant 20 is effectively absorbed when the cornea is worn on the cornea damaged by external factors such as nails and the like or surgical factors such as LASIK or LASEK, The effect can be doubled and a cooling sensation can be provided to the wearer at the same time.
