The invention relates to a multifunctional bioceramic orbital implant and a preparation technology thereof. The multifunctional bioceramic orbital implant is characterized in that a standard spherical porous bioceramic is prepared through accurate control of a mould and a pore-forming bracket; the surface structure or/and internal structure of the orbital implant is/are adjusted so as to enable the orbital implant to have different performance and functions. The homogeneous, hollow and sewable porous bioceramic orbital implants, and a gradient porous bioceramic orbital implant can be prepared through the preparation technology provided by the invention; the orbital implant has the advantages as follows: the material structure meets requirements of tissue growth and vascularization, so that the orbital implant can form permanent biological integration in an organism; the high-porosity material is relatively light in weight, so that the retaining of the mobility of the orbital implant is facilitated; the gradient porous bioceramic structure is adopted, so that the surface roughness can be reduced greatly, and abrasion to orbital bones bythe implanted orbital implant is reduced effectively; the sewable structure is adopted, so that tissue sewing and fixation are facilitated, especially the fixation of the dynamic muscle of an eyeball on the orbital implant is facilitated. The orbital implant provided by the invention is used for body repairing abouteyeball missing and psychic trauma improvement in the medical field of ophthalmology.
