Machinable Ceramic Ocular Prosthesis
Ceramic prosthetic eye is a high-precision customized prosthetic eye based on bioceramic materials (such as medical zirconia and hydroxyapatite composites), and its core purpose is to provide functional repair and aesthetic reconstruction for patients with missing or severely damaged eyeballs, which are infinitely close to natural eyeballs in terms of function and aesthetics, and provide patients with lifelong maintenance-free biomimetic solutions.
With zero porosity, antibacterial property and biological inertness, ceramic prosthetic eye completely solves the problems of bacterial breeding (leading to conjunctivitis) and aging and discoloration (need to be replaced in 2-3 years) of traditional resin prosthetic eye, and replaces traditional acrylic prosthetic eye in the field of medical rehabilitation. It is suitable for complex eye socket structures, and can obtain point cloud data (accuracy 0.02mm) by laser scanning eye sockets, and perform five-axis CAD/CAM engraving→ high-temperature sintering (1500°C) → glaze layered coating (> 20 times) processing, Ra ≤ 0.1μm, accurately match the anatomy of the patient's eye socket (especially suitable for deformed orbits after trauma/tumor surgery), and reduce the risk of frictional ulcers.
Because ceramic materials (such as high-purity alumina) do not release monomer residues, acrylic-induced allergic conjunctivitis is avoided. The surface is coated with a bioactive film (e.g., diamond-like carbon coating) to promote conjunctival cell adhesion.
The ceramic glaze layer is resistant to ultraviolet aging, and the color difference value is <1.5 (unrecognizable to the naked eye) within 10 years, avoiding the trouble of reworking and repainting the iris pattern of the traditional prosthetic eye every year.
