METHOD FOR PRODUCING OPTICAL LENSES OF ORGANOSILICON MATERIAL Russian patent published in 1994 - IPC

Abstract RU 2017470 C1

FIELD: medicine. SUBSTANCE: polymerization is carried out at 170-180 C within 13-17 min or at 125-135 C within 48-52 min. The process takes place inside form having high heat conductivity (e.g. of aluminium having gradient 115-125 s). Indexes of light transmission of desired article at 2000-2200 cm-1 are registered to detect usefulness of article. The process is followed by gamma sterilization. EFFECT: increases biological compatibility, improves efficiency of the method. 1 tbl
