A composition for preventing or treating an eye disease includes adiponectin as an active ingredient. Adiponectin as an active ingredient is eventually revealed to show prevention or therapeutic efficacies for eye diseases such as dry eye (syndrome), inflammatory eye disease and side effects due to the use of contact lenses by promoting tear secretion, alleviating ocular surface irregularities, decreasing inflammatory cytokines on the ocular surface and lacrimal gland, and increasing conjunctival goblet cell density. In addition, the composition having eye contact lubrication effects may be used as cleaners or lubricants for preventing non-bacterial inflammation due to wearing contact lenses.

The invention provides an external traditional Chinese medicinal composition for treating xerophthalmia and a preparation method thereof. The external traditional Chinese medicinal composition for treating the xerophthalmia is prepared from the following raw materials: wolfberry, chrysanthemum, salviae miltiorrhizae, cortex phellodendri, pearl powder, borneol and menthol. The external traditional Chinese medicinal composition for treating the xerophthalmia has the advantages that pathological changes of lacrimal gland tissues of an experimental xerophthalmia mouse, lacrimal glands of which are damaged by injected pingyangmycin, in morphology can be obviously alleviated, quantity of tear fluid can be obviously increased, breakup time of a tear film is prolonged, and quantity of the tear fluid secreted by a normal domestic rabbit can be obviously increased.

This invention provides a prophylactic and therapeutic agent for dry eye, having new ingredients to reduce the deterioration of the lacrimal secretory ability and to inhibit the generation of radical oxygen in lacrimal gland tissue. The prophylactic and therapeutic agent for dry eye of this invention contains the maqui berry extract as the active substance of this invention, i.e. containing delphinidin glycoside extracted from the maqui berry and at least one or more of the active substances delphinidin-3-sambubioside-5-glucoside, delphinidin-3,5-diglucoside, delphinidin-3-sambubioside and delphinidin-3-glucoside, preferably delphinidin-3,5-diglucoside.

The invention puts forward eye-protecting health care plaster, which comprises active ingredients and absorption-accelerating ingredients. The eye-protecting health care plaster comprises the following ingredients in parts by weight: 2-8 parts of flos buddlejae, 3-8 parts of flos chrysanthemi indici, 5-15 parts of herba menthae, 5-12 parts of ginseng radix, 5-12 parts of stigma croci, 5-12 parts of spica prunellae, 2-10 parts of folium mori, 4-15 parts of semen cassia, 5-15 parts of semen plantaginis, 1-10 parts of radix saposhnikoviae, 1-5 parts of radix salviae miltiorrhizae, 1-6 parts of rhizoma coptidis, 2-7 parts of phellodendri chinensis cortex and 5-13 parts of herba equiseti hiemalis. The invention provides the eye-protecting health care plaster, the prepared eye plaster has mild performance and provides good protection for the eye skin, and meanwhile, the eye-protecting health care plaster has the functions of increasing the blood flow speed of the periphery of eyes, eliminating bulbar conjunctival microcirculation disturbance of the eyes, preventing from forming microcirculation disturbance and effectively alleviating asthenopia. Finally, the eye-protecting health care plaster can obviously improve the ultramicrostructure of lacrimal gland tissues, stimulate the lacrimal gland to increase secretion volume and further improve the stability of the lacrimal film.

The invention discloses a surgical operation method. A pupil and embolus fixing part are included, wherein a lacrimal gland catheter is mounted above a pupil; a lacrimal gland is mounted above the lacrimal gland catheter; an upper lacrimal punctum is mounted above one side of the pupil; an angle of eye medial is mounted below one side of the pupil; a lower lacrimal punctum is mounted on one side of the angle of eye medial; a main lacrimal duct is mounted on one side of the middle of the pupil; the main lacrimal duct is internally provided with a lacrimal sac; a naso-lacrymal duct is arranged inside the lacrimal sac; a silicone tube is arranged inside the naso-lacrymal duct; and the embolus fixing part is positioned below the silicon tube. By adopting the operation method, dirt accumulatedin a lacrimal passage cavity can be sufficiently flashed out from inside to outside, continuous cleanliness of the lacrimal passage cavity can be maintained, lacrimal passage inflammation reactions can be alleviated, the lacrimal passage cavity can be prevented from re-occurrence of adhesion and sealing, and thus the treatment effect can be improved.

The invention discloses a special lacrimal gland retractor for an ophthalmologic operation, which structurally comprises a liquid collecting rack wheel groove, nipper rod frames, battens, a cross-shaped sleeve rod seat, a piston rod and a finger pressing column cap. The special lacrimal gland retractor for the ophthalmologic operation achieves effects that the liquid collecting rack wheel groove is applied to be matched with the nipper rod frames, a frame rail annular groove and flow drawing brush frame bases are erected at the position of the eyelid by the nipper rod frame to adjust a thickness of care solution to avoid refraction and guarantee a thin layer to cover the eyeball and the pupil end so as to form an anti-interference operation effect of the care solution during the eye surgery; after the lacrimal gland position is effectively exposed,the lacrimal sac is subjected to precise knife feeding cutting, and an effective close-range detection deviation value is sensed inside by adiode fan base and a groove relay disc so as to facilitate the correction operation effect of a scalpel; the auxiliary promotion of a thin frame appliance for retracting the lacrimal gland when the eyelid and the eyeball are subjected to cushioning protection is improved; surgical eye closing is guaranteed to be rapidly completed; and internal solution is carded to form a postoperative retractingoperation timely closing maintenance effect.
