Embodiment Construction

[0017] Below in conjunction with accompanying drawing and preferred a kind of specific embodiment structure of the present invention is described further:

[0018] refer to figure 1 and figure 2 As shown in , the present invention is mainly composed of two parts, the optical zone 1 and the skirt 2 .

[0019] The said skirt 2 is arranged on the periphery of the optical zone 1, and is used to fix and support the optical zone 1. The skirt is a biological material compatible with human eye tissue. The biological material is preferably hydroxyapatite, but not excluded Or include other histocompatible biomaterials. Hydroxyapatite is a kind of nano-biological material, which has many pores when mixed with other materials, and human corneal tissue can grow into it, with good biocompatibility.

[0020] In order to promote the growth of nerves and blood vessels, the hydroxyapatite pores on the skirt 2 are provided with substances that promote the growth of nerves and blood vessels, ...

Abstract

An artificial cornea has an optical zone (1) and a skirt (2) equipped with the periphery of the optical zone (1). The inner surface (22) and outer surface (21) of the skirt (2) are equipped with biomaterial coatings compatible to human eye tissues. An edge of the skirt (2) is zigzag, and more than four through holes (23) are disposed on the skirt (2). The edge of the skirt (2) is zigzag, so that the skirt (2) can adapt to varied cornea radian easily, and the irregular jointing caused by the heaving of the skirt (2) is avoided. More than four through holes (23) are disposed on the skirt (2), such that the fixation of sutures is facilitated, fusion, fiber growth, nutrition communication and the like of anterior and posterior lamellar corneas and the artificial cornea are strengthened, and the biocompatibility of the cornea is enhanced.

Description

technical field [0001] The invention relates to the technical field of artificial corneas, in particular to the connection structure and function improvement of artificial corneas. Background technique [0002] At present, due to the different curvatures of the corneas of different people, the artificial corneas are prone to mismatching curvatures when implanted between the human corneal lamina, which will affect the surgical connection between the two. In addition, when the artificial cornea is implanted, the anterior lamellar cornea is in contact with the outer surface of the artificial corneal skirt, and the posterior lamellar cornea is in contact with the inner surface of the artificial corneal skirt. The inconsistency of the curvature of the layers will cause the two to be not tightly attached, which will affect the stability of the artificial cornea. In addition, the connection between the transparent body and the skirt of the existing artificial cornea is the same pl...
