Biocompatible drainage pipe for glaucoma aqueous humor and preparation method thereof

Abstract

The invention discloses a biocompatible drainage pipe for glaucoma aqueous humor and a preparation method thereof. A template-freezing method is used for preparing a chitosan micro tube which is usedas a glaucoma drainage device, so that a stable biocompatible aqueous humor drainage channel is obtained. The preparation technology is simple, and the cost is low. The obtained chitosan micro drainage tube facilitates sterilization, packaging and transportation, and is a glaucoma aqueous humor drainage product which is low in cost, portable and practicable.

Description

technical field

[0001] The invention specifically relates to the technical field of ophthalmic medical implant materials, in particular to a biocompatible glaucoma aqueous humor drainage tube and a preparation method thereof. Background technique

[0002] Glaucoma is the second leading cause of blindness worldwide. Glaucoma is a kind of optic nerve damage disease caused by pathological high intraocular pressure. Controlling intraocular pressure has become the main means of glaucoma treatment. Although anti-glaucoma drugs and laser technology provide the technology and possibility to control intraocular pressure, due to the particularity of the disease, a considerable number of glaucoma patients have to undergo surgery. Clinically, anti-glaucoma surgery is the ultimate treatment that can effectively control the development of the disease. This operation is to create a channel from the inside of the eye to the subconjunctival outside the eyeball wall by removing the trabecul...
