Problems solved by technology

Cataract surgery can lead to acute endophthalmitis. Endophthalmitis is difficult to predict and is the most troublesome thing for ophthalmologists. The incidence of the syndrome has a certain relationship with the reconstruction of the wound. It is related to factors such as changes in intraocular pressure, but for postoperative trauma in eye surgery, there is currently no method that can effectively seal the wound and avoid fluid leakage

Abstract

A liquid eye dressing, a preparation method thereof and a liquid eye dressing product relate to the field of medical materials. The liquid eye dressing includes 5%-30% powder and 70%-95% solution by mass percentage, the powder includes modified polyethylene glycol, and the solution contains polyethyleneimine, dithiothreitol and trilysine Buffered solutions of acids; liquid eye dressings products include powders and solutions in separate packages, and medical sponge swabs for agitation and application. Stir the powder and solution evenly with a medical sponge swab. The curing time is 10-30s. The process is simple. The prepared liquid eye dressing can be used for ophthalmic surgery, especially for eye wounds after cataract surgery, which can reduce the operation time and improve vision. The recovery is accelerated, there is no foreign body sensation after use, and at the same time, an antibacterial barrier is formed at the surgical site to reduce the occurrence of inflammation, and it can also reduce leakage, which can block bacterial infection, relieve pain, and increase the comfort of the patient's eyeballs.

Description

technical field [0001] The invention relates to the field of medical materials, and in particular to a liquid eye dressing, a preparation method thereof and a liquid eye dressing product. Background technique [0002] In ophthalmic surgery, the postoperative incision is mainly treated with sutures. The suture process requires time and skill. At the same time, traditional ophthalmic sutures will cause corneal wounds, and sutures may cause infection and affect the formation of new blood vessels. Prolong the healing time and easily cause eye inflammation and discomfort. [0003] Cataract is the leading cause of blindness in the world (Brian G, Taylor H. Cataract blindness-challenges for the 21 st century[J].Bull Word Health Orange,2001,79(3):249-256), and also the first blinding eye disease in my country (Li Dexin, Wang Siling, Su Desen, Pathogenesis and drug treatment of cataract[J]. Journal of Shenyang University of Science and Technology, 2002,19(4):300-307). There are ab...
