Embodiment Construction

[0013] The technical solutions of the present invention will be further illustrated and described below through specific embodiments. Those skilled in the art can understand that the following specific embodiments are only for the purpose of further elaborating the present invention, rather than limiting the protection scope of the present invention in any way.

[0014] Such as figure 1 As shown, the hydroxyapatite medical artificial cornea described in the present invention comprises a central optical mirror column (1), a fixed part (2) arranged at the periphery, and a cylindrical side outer surface of the artificial cornea central optical mirror column (1) and the inner surface of the peripheral fixing part (2) is coated with a hydroxyapatite coating (3).

Abstract

The invention discloses a keratoprosthesis. The keratoprosthesis comprises a central opticator and a fixed portion arranged in the periphery, and the keratoprosthesis is characterized in that a hydroxylapatite coating (3) is smeared on a cylinder lateral outer surface of the central opticator and the inner surface of the fixed portion (2) in the keratoprosthesis, and average grain diameter of nanoparticle of the coating is 20 nm. The keratoprosthesis has the advantages that isolation of the coating and an anti-microbial property of the hydroxylapatite are made use of, after smearing the coating and the hydroxylapatite on the cylinder outer surface of the keratoprosthesis opticator and the inner surface of the fixed portion of the periphery of the opticator, a role of killing effect on microorganisms such as germs which are in contact with a cornea and aqueous humor of a patient is thus played by the coating and the hydroxylapatite; due to the fact that the hydroxylapatite can smear the periphery of the keratoprosthesis opticator for a long time, intrinsic characteristics of keratoprosthesis materials are not changed, intrinsic characteristics of the keratoprosthesis are still maintained so that treatment and nursing can reach optimal effects.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to a coated medical artificial cornea with increased biological integration. Background technique [0002] Artificial corneas are the ultimate means of vision recovery for patients with corneal cloudiness who cannot recover their vision with corneal surgery. In order to achieve the ideal optical effect, the artificial cornea mostly adopts the penetrating type at present, that is, the optical part of the artificial cornea penetrates the whole layer of the cornea, and the optical part is fixed in the center of the cornea through the bracket, so there is a certain gap between the optical part of the artificial cornea and the surrounding bracket and tissue structure . Clinically, because of these potential cavities, the chance of microorganisms entering the eye is increased, which may lead to the occurrence of endophthalmitis, the most serious complication after artificial cornea surg...
