The invention discloses a multifunctional artificial eye seat with an adjustable microporous structure and a preparation method. The multifunctional artificial eye seat is prepared from a porous material which takes undoped or heterogeneous
ion doped akermanite biological
ceramic as a main component. Micro pore scales form gradient
pore distribution from outside to inside,
mire pores communicate with one another to form a curved-surface pore
cell structure and have a plurality of
radius ranges, and the pore diameters of the micro-pores are gradually increased to form a gradient structure. The preparation method comprises the following steps: mixing
tetraethyl orthosilicate with deionized water and
nitric acid, performing stirring and hydrolyzing, then adding
calcium nitrate and
zinc, performing stirring into a
gel state, performing aging, performing
drying, performing calcining, and performing ball-milling to obtain superfine
zinc melilite powder; and adding liquid photosensitive printing resin to form
slurry, performing uniform stirring and mixing, performing three-dimensional printing, removing residual
slurry, and performing
drying and
sintering to obtain a product. The artificial eye seat keeps biological stability
in vivo for a long time, and can
resist bacteria, regulate
inflammatory response and promote
angiogenesis; the structure is accurate and adjustable, and
vascular tissue can be promoted to rapidly grow into a pore
channel network; and the preparation process is simple and convenient, and postoperative complications are remarkably reduced.
