Abstract： |
A process for preparing artificial eye ball includes such steps as dissolving the biocompatible polymer in solvent to obtain saturated solution, mixing it with sieved pore-forming agent (300-600 microns), die pressing to obtain circular ball, volatilizing solvent, immersing the ball in the swelling solution prepared from trigger, cross-linking agent and polymer monomer, introducing nitrogen gas, sealing, swelling for 3-100 hr, putting the ball in reactor, introducing nitrogen gas, sealing, polymerizing, and immersing the ball in deionized water for 72 hr. Its advantages are high precision of size, high porosity (more than 80%), and high performance. |
