Embodiment Construction

[0023] A preferred embodiment of the present invention provides a method for making an artificial corneal stent 200 (see Figure 4 ), which includes the steps of:

[0024] Step S401, providing an artificial corneal stroma 100;

[0025] Step S402, providing a collagen solution, putting the artificial corneal matrix 100 into the collagen solution for 5 minutes to 60 minutes, then taking it out and air-drying, that is, forming simulated corneal matrix 100 on opposite surfaces of the artificial cornea matrix 100 respectively. The Bowman's membrane 201 and the Bowman's membrane 202 are simulated to obtain the artificial corneal stent 200 .

[0026] see figure 1 , the artificial corneal stroma 100 in step S401 is made of an artificial corneal stroma material.

[0027] The artificial cornea matrix material includes methacrylated hyaluronic acid, collagen, photoinitiator and solvent.

[0028] In the artificial cornea matrix material, the mass percentage of methacrylated hyaluronic...

Abstract

The invention relates to an artificial cornea stroma. The artificial cornea stroma is made of an artificial cornea stroma material. The artificial cornea stroma material comprises methacrylated hyaluronic acid, collagen and a photoinitiator. The artificial cornea stroma has nano patterns on the surface. The invention further relates to a method for preparing the artificial cornea stroma and an artificial cornea frame with the artificial cornea stroma.

Description

technical field [0001] The invention relates to an artificial corneal stroma and a manufacturing method thereof, as well as an artificial corneal support comprising the artificial corneal stroma. Background technique [0002] The cornea is an avascular, optically transparent tissue that serves to refract and filter light before it enters the eye. The cornea is composed of five layers, from outside to inside are the epithelium, Bowman's membrane, stroma, Bowman's membrane and endothelium. Among them, the corneal stent composed of Bowman's membrane, stroma and Bowman's membrane cannot be regenerated, once damaged, it will not be able to regenerate. At present, many blind patients are caused by corneal disease, which has become the second leading cause of blindness after cataract. Patients with blindness caused by corneal disease can generally be relieved of blindness through corneal transplantation. However, there are few sources of corneal donors.
