The invention provides a method for treating pterygium, and relates to a method for treating ophthalmic diseases. The method for treating pterygium solves the problem that an existing pterygium cutting method is high in recurrence rate. Limbal stem cell transplanting is used for treating pterygium, the bulbar conjunctive at a sclera exposure area is reconstructed and repaired, local epithelial tissue at the limbus corneae is reconstructed and repaired, healthy stem cells are provided for the cornea epithelium, and the limbus corneae shielding function is reconstructed. Conjunctive epithelium and new vessels are prevented from invading the cornea. Limbal stem cell transplanting is used for treating pterygium, so that the method has the advantages that an operation is quick and safe, and reoccurrence is avoided after the operation.

This invention is within the field of eye medicine, involving the preparation method of one type of cornea intravital staining. The above mentioned staining includes the mixed solution of fluorescein sodium aqueous solution and lissamine green aqueous solution. In the above fluorescein sodium aqueous solution, the concentration of fluorescein sodium is 0.5%-4.0% w/v; while in the above lissamine green aqueous solution, the concentration of lissamine green is 0.5%-4.0% w/v. And the volume ratio of the above mentioned fluorescein sodium aqueous solution and lissamine green aqueous solution is 1:0.25-1:3. The cornea intravital staining in this invention possesses some advantages like making the staining of cornea and bulbar conjunctiva proceed at the same time, completed by one time, little irritation to eye tissue and being susceptive for patients. And it is mainly used in diagnosing and evaluating xerophthalmia, keratohelcosis, keratitis (KCS), arborized corneal epithelium herpes, and early diagnosis of Sjogren syndrome etc.

The invention belongs to the traditional Chinese medicine field, relates to a traditional Chinese medicine prescription for treating xerophthalmia and a preparation method, and more specifically to a compound dendrobium eye drops for treating xerophthalmia and a preparation method thereof. The compound dendrobium eye drops are prepared from the following raw materials: 80-120g of caulis dendrobii, 80-120g of radix trichosanthis, 80-120g of folium isatidis, 50-100g of vitamin B1, and 10-20ml of honey. The eye drops are prepared by a modern advanced medicine pharmaceutical technology and have a reasonable formula which is scientific and advanced. The medicinal herb resource is abundant and the medicine cost is low. The traditional Chinese medicine prescription for treating xerophthalmia has the efficacy of improving eyesight and anti-inflammation, lubricating eye surface, and prompting cornea epithelium growth. A local drug delivery mode is employed, and the medicines directly reach the action position. The compound dendrobium eye drops for treating xerophthalmia provides a safe and effective eye medicinal preparation with convenient use for clinic treatment of the xerophthalmia. The treatment effect is reliable, and the compound dendrobium eye drops for treating xerophthalmia and the preparation method thereof can be popularized.

The invention discloses eye washing liquid for preventing xerophthalmia and a preparation method thereof. The eye washing liquid is prepared from the following raw materials: 60g to 80g of cornflowers, 80g to 100g of folium isatidis, 20g to 40g of herba menthae, 20g to 30g of vitamin A, 6ml to 8ml of honey and 6ml to 8ml of pearl liquid. The eye washing liquid is prepared by adopting the modern advanced medical pharmaceutical technology, is reasonable in formula, and has scientificity and advancement; the selected materials are rich in medicine source; the medicinal materials are low in cost;the eye washing liquid has effects of improving eyesight, resisting to inflammation, lubricating the ocular surface, prompting corneal epithelium to grow; a local administration mode is adopted; medicine directly reaches an acting position; an eye medicinal preparation which is safe, effective and convenient to use is provided for clinical treatment on xerophthalmia; and the eye washing liquid isreliable in treatment effect and has generalizability.

The invention provides a cornea protective agent. The cornea protective agent comprises hydroxypropyl methyl cellulose with the viscosity of 5mPa.S to 200,000 mPa.S and/or chondroitin sulfate with the molecular weight of 20,000 to 500,000, an anti-inflammatory substance and a buffer solution. The cornea protective agent disclosed by the invention can protect the cornea surface in an operation, can keep the cornea surface moist within a certain time and keep good transparency of the cornea, and provides a good operation visual field. Meanwhile, the risk of postoperative corneal epithelium dysfunction can be reduced, and postoperative complications are reduced.

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.

A corneal bandage lens prepared by the preparation method of the corneal bandage mirror provided by the embodiment of the invention has the advantages that the structure is simple; when the corneal bandage lens is applied to vitreous surgeries, in the surgery, the visual field of doctors is kept clear for a long time; generally greater than 10 minutes, if sharpness has decreased, a small amount ofbalanced salt solution is utilized; washing the surface of the corneal bandage lens; and when the sclera is pressed and the eyeball is rotated, the visual field of the doctor is not obviously deformed in the operation, and after the existing corneal bandage mirror is improved, the corneal bandage mirror is applied to the vitreous operation, so that the burden of an assistant is greatly reduced, the operation efficiency is improved, and the clinical application range of the existing corneal bandage mirror for treatment is expanded. Meanwhile, it is found that after the corneal bandage lens isremoved after the surgery is finished, the corneal epithelium integrity and the corneal epithelium edema degree of the operation eye are superior to those of a traditional balanced salt solution flushing set, and therefore the existing corneal bandage lens for treatment also has a clear protection effect on corneas in vitreous body operation.

The invention discloses a marker pen for implanting an astigmatism correction type intraocular lens. The marker pen comprises a pen body, a coloring part and a cutting part, wherein dye is contained in the pen body; the coloring part is arranged at the end part of the pen body, so that the dye flows out from the coloring part; and the cutting part is arranged at the front end of the coloring part.A medical worker can complete cutting operation of corneal epithelium and the clear and fine marking operation of marking points A and B by independently using the marking pen, and does not need to cut the corneal epithelium by using a syringe needle and then perform coloring marking by using the marking pen, so that the operation steps of implanting the astigmatism correction type intraocular lens are simplified, and the operation time is shortened.
