Embodiment 1

[0030] Get the purchased raw materials and grind them into powder, and weigh them according to 10 grams of xuanming powder, 20 grams of borax, 15 grams of mirabilite, 25 grams of calamine, and 40 grams of borneol.

[0031] Mix Xuanming powder, borax and Glauber's salt, add 180ml of water for injection, stir and dissolve at 80°C for 45 minutes. Add calamine to 180 ml of 0.1 mol / l boric acid solution (wherein the solvent is water for injection), heat and stir at 80° C. for 45 minutes. The borneol was firstly mixed with Tween-80, then water for injection at 50°C was added, and heated and stirred at 80°C for 45 minutes. Mix the supernatant after heating and dissolving the above raw materials, adjust the pH value to 7.4 with 0.1mol / l boric acid solution, add water for injection to 1000ml, add sodium chloride to adjust the osmotic pressure, so that the eye drops are equivalent to 0.9% sodium chloride Concentration, finely filtered until clear, sterilized with circulating steam at 1...

Abstract

The invention relates to eyedrops for treating presbyopia, which comprise the following effective components proportioned according to parts by weight: 1 to 2 parts of natrii sulfas exsiccatus, 1.6 to 3 parts of borax, 1 to 2 parts of Glauber's salt, 1 to 3 parts of calcined calamine and 1.6 to 4 parts of borneol. The eyedrops for treating the presbyopia also contain an amount of water as a solvent. The invention also discloses a preparation method of the eyedrops. The eyedrops disclosed by the invention not only have an obvious curative effect on the presbyopia, but also have a good curativeeffect on dry eyes.

Description

technical field [0001] The invention relates to an eye drop, especially an eye drop for treating presbyopia. The invention also provides a preparation method of the eye drops. Background technique [0002] Presbyopia, also known as presbyopia, is a manifestation of the aging of the eyes of the elderly. Everyone knows that everyone has an aging process, such as the graying of the hair, loose skin, and muscle atrophy of the elderly. The adjustment function of the eyes will also age. With the increase of age, the elasticity of the lens gradually decreases, and the function of the ciliary body gradually weakens. When looking at nearby objects, the lens cannot become convex, and the image cannot be focused on the retina. Objects are very clear. When reading a book, you should hold the book farther away, or require sufficient light to see clearly. These conditions are presbyopia. [0003] The etiology and pathology of presbyopia: presbyopia is a natural physiological aging pheno...
