Claims (1)

1. Process of artificial eyeball - hydroxyapatite with porous, movable porous, implantable Containing Steps are as follows: a. Preparation of slurry hydroxyapatite juice Mix hydroxyapatite with distilled water. Grind the mixture with zirconia balls in a grinding pot for 12-36 hours, then add additives - binder, plasticizer. (Plasticizer) and dispersant Then continue grinding to make the mixture homogeneous. B. Preparation of polymers for the contour of the artificial eye diameter. Of artificial eyeball 16 - 20 mm. C. Polymer foam coating with hydroxyapatite water. The prepared polymers were immersed in slurry with 20-60 s and 4-7 cycles of dipping in vacuum. After that, the polymer foam coated with slurry. Then go to freeze in a chiller at a temperature of -20 to -100 degrees Celsius and freeze the substance until it freezes. And evaporate to remove ice (Freeze dryer) for 24-30 hours. D. Sintering at temperatures in the range of 1200-1400 degrees Celsius for 2-5 hours.
