Abstract: Compared with metal, polymer and other biomaterials, bioceramic materials have good biocompatibility and physicochemical stability, and are mainly used to repair biological hard tissues such as bones and teeth. At present, it shows good histocompatibility and physicochemical stability in fields of ophthalmology. Bioactive glass is used to make the skirt of artificial cornea, and hydroxyapatite is often used in orbital repair. In addition, hydroxyapatite and β-tricalcium phosphate (β-TCP) are also commonly used in orbital fracture repair and defect repair. Alumina and composite materials can be used to make artificial eyes to increase their stability.  (Int Rev Ophthalmol, 2024, 48: 145-150)
