Problems solved by technology

If timely and correct treatment is not received or improper care is taken during treatment, the condition may deteriorate rapidly, which may cause corneal and conjunctival adhesions, blindness, and even purulent panophthalmitis, eventually leading to loss of eyeball
[0004] At present, the treatment methods for animal corneal diseases are mostly drug therapy and surgical treatment, but the drugs need to be repeatedly administered to the sick animals every day, and when the drugs are on the surface of the animal cornea, they are easy to evaporate or be rubbed off by the animals, which is not easy to maintain.
Surgical treatment requires conjunctival flap covering, but there is no barrier between the cornea and conjunctiva after surgery, and the cornea and conjunctiva are prone to adhesion

Embodiment 1

[0032] like Figure 4 Shown is a front view and a side sectional view of Embodiment 1 of the present invention. The animal corneal protective lens is made of soft transparent hydrophilic acrylic material, the oxygen permeability coefficient DK (ISO; hPa) is 32, and the water content is 72%. The lens 301 includes two circular apertures 302 . The total diameter 305 of the lens 301 is 14.0 mm, the radius of curvature 304 of the base arc of the lens 301 is 8.3 mm, the central thickness 306 of the lens 301 is 0.05 mm, and the diameter of the circular hole 302 is 1.5 mm.

[0033] This embodiment is suitable for use by cats or ultra-small dogs suffering from dry eye syndrome, and is mainly used for storing medicinal liquid and keeping the cornea moist. The design size of the center thickness 306 is 0.05mm. For small-sized eyeballs, the center thickness 306 reduces the oppressive effect of the protective lens and reduces the pain of the animal; the design size of the base arc curvat...

Embodiment 2

[0035] like Figure 5 Shown is a front view and a side sectional view of Embodiment 2 of the present invention. The animal corneal protective lens is made of soft transparent hydrophilic acrylic material, the oxygen permeability coefficient DK (ISO; hPa) is 32, and the water content is 75%. The lens 401 includes two square apertures 402 . The total diameter 405 of the lens 401 is 18.0 mm, the radius of curvature 404 of the base arc of the lens 401 is 9.6 mm, the central thickness 406 of the lens 401 is 0.12 mm, and the side length of the square hole 402 is 1.2 mm.

[0036] This embodiment is suitable for use in medium-sized dogs with corneal ulcers, and is mainly used for corneal wound healing and relief of animal eye pain. The design size of the central thickness 406 is 0.12mm. For medium-sized eyeballs, the central thickness 406 increases the pressure of the protective lens and reduces the pain of the animal; the design size of the base arc curvature radius 404 is 9.6mm, w...

Embodiment 3

[0038] like Image 6 Shown is a front view and a side sectional view of Embodiment 3 of the present invention. The corneal protective lens for animals is made of soft hydrophilic acrylic material, dye and ultraviolet absorber are added, it is gray in color, the oxygen permeability coefficient DK (ISO; hPa) is 45, and the water content is 74%. The lens 501 includes two irregularly shaped apertures 502 . The total diameter 505 of the lens 501 is 35.0 mm, the radius of curvature 504 of the base arc of the lens 501 is 18.0 mm, the central thickness 506 of the lens 501 is 0.12 mm, and the maximum diameter of the irregular small hole 502 is 1.2 mm.

[0039] This embodiment is suitable for racing horses, and is mainly used for windproof, sandproof, and light intensity reduction. The design size of the central thickness 506 is 0.12 mm. For large-sized eyeballs, the central thickness 506 reduces the oppressive effect of the protective lens and can avoid a strong foreign body sensatio...

Abstract

The invention discloses animal cornea protection glasses which comprise lenses, the lenses are in a concave-convex lens shape and are provided with smooth inner surfaces and outer surfaces, the outer surfaces of the lenses are convex surfaces, the inner surfaces of the lenses are concave surfaces, the lenses are composed of inner lens layers and outer lens layers, and colorful ring bands are filled between the inner lens layers and the outer lens layers at the edges of the lenses in a film pressing mode. Two round, square or irregular small holes are further formed in the edge of the lens, the lens is made of a soft hydrophilic material with high oxygen permeability and high water content, and the oxygen permeability coefficient DK is smaller than ISO; the soft contact band-aid and the therapeutic lens are specially designed for animals, are soft contact band-aid and the therapeutic lens, can prevent the cornea from being dry or stimulated and prevent pets from touching the cornea when being worn on the surface of the animal cornea, and can be used for preventing the cornea from being damaged. Meanwhile, therapeutic drugs can be dropwise added between the lens and the cornea, so that corneal epithelium regeneration is promoted, and pain is relieved.

Description

technical field [0001] The invention relates to the technical field of soft corneal contact lenses, in particular to a corneal protective lens for animals. Background technique [0002] With the change of social structure and the development of social economy, the groups of living alone and empty nests gradually expand, and pets gradually become emotional sustenance. According to the survey data, 37.1% of the respondents regard pets as their friends, and more than 40% of the respondents regard pets as relatives. This emotional demand promotes the development of the pet medical economy. The data shows that the scale of China's pet medical care market will increase to 267 billion yuan in 2021. With the increase in the number of pets, the pet medical market will have huge room for development in the future, with an average annual growth rate of more than 10%. [0003] Corneal ulcers, corneal perforations, and eyelid defects are the most common ophthalmic diseases in animals. ...
