A kind of contact lens for treating glaucoma

Abstract

The invention discloses a contact lens for treating glaucoma. The contact lens is a spherical-crown-shaped cornea contact lens (1) as a whole and mainly comprises a soft layer (8) and a hard layer (7); the contact lens is prepared through a plane bonding process and a hot-pressing forming process; the soft layer (8) is located on the inner layer of the cornea contact lens (1), and the hard layer (7) is located on the outer layer of the cornea contact lens (1); a micro-fluid channel (3) and a hollow cavity (4) are further formed in the cornea contact lens (1), and the hollow cavity (4) is usedfor storing liquid medicine (5); the micro-fluid channel (3) is used for conveying the liquid medicine (5). The material of the contact lens and the internal structure and corresponding process of thelens are improved, so that the contact lens serves as a medicine delivery system; abnormal intraocular pressure of a patient suffering from glaucoma is used for triggering medicine delivery, and theliquid micro-cavity in the soft layer can be extruded according to increase of the intraocular pressure so as to carry out continuous medicine delivery, and the bioavailability is high.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and more specifically relates to a contact lens for treating glaucoma. The contact lens is a set of contact lenses designed for glaucoma. The contact lens can be used to treat glaucoma according to the activities of the glasses. And ensure that the contact lens can carry out continuous drug administration to the eyeglasses, so as to ensure the therapeutic effect. Background technique [0002] Glaucoma refers to an eye disease in which the intraocular pressure is intermittently or continuously increased. Sustained high intraocular pressure can cause damage to various parts of the eyeball and visual function. Increased intraocular pressure can cause depression of the optic disc (formerly known as the optic disc) and visual field defects. , a serious eye disease that can eventually lead to blindness. The reason for increased intraocular pressure in glaucoma is that the dynamic balance of aqu...

Problems solved by technology

[0004] For the above defects or improvement needs of the prior art, the object of the present invention is to provide a contact lens for the treatment of glaucoma, wherein through the material of the contact lens and the internal structure of the lens (especially the microfluidic channel, the hollow cavity and the outlet The overall structure of the liquid port, and the specific shape and size parameters of each microfluidic channel, hollow cavity and liquid outlet, etc.) design and corresponding process are improved, and the contact lens is used as a drug delivery system to treat the abnormal intraocular pressure of glaucoma patients. Triggered administration, compared with the traditional treatment method of using eye drops, on the premise of ensuring that the contact lens does not affect vision, it can squeeze the liquid microcavity in the soft layer according to the increase in intraocular pressure for continuous administration , to overcome the shortcomings of traditional drug delivery methods that cannot guarantee continuous therapeutic effect and poor bioavailability, and has higher bioavailability and lower treatment risk
