| titleOfInvention | Soft porous silica gel artificial eye holder and preparation method thereof |
| abstract | The invention discloses a soft porous silica gel artificial eye holder and a preparation method thereof. The porous material is prepared by a silica gel material, has a high-porosity interpenetrating porous structure, and micropores on the surface and inside are uniformly distributed and communicated with each other; sequentially adding half of the gelatin particles into a hemispherical polytetrafluoroethylene die, permeating with ethanol water solution, drying at constant temperature, bonding and forming, mixing the silica gel prepolymer and the cross-linking agent, and uniformly mixing under mechanical stirring to obtain a silica gel prepolymer mixture; and introducing the negative pressure silica gel prepolymer mixture into a spherical gelatin template for crosslinking and curing, and removing the template in a constant-temperature water bath to obtain the soft porous silica gel artificial eye holder. The pure silica gel artificial eye base has good biocompatibility and biological stability, controllable pore diameter, good pore connectivity and extremely high porosity, improves the survival rate of the implant through structural and mechanical property optimization, and reduces postoperative complications; and the method is simple and the material cost is low. |
