METHOD OF PREPARING COMPOSITE POLYMER RODS USEFUL FOR PREPARING SINGLE-PIECE INTRAOCULAR LENSES WITH COLORED HAPTICS |
摘要 |
Composite acrylic polymer rods having clear central regions and colored peripheral regions are prepared by subjecting to polymerization conditions a rod of acrylic polymer surrounded with a flowable solution comprising acrylic monomer, dye and, dissolved therein, acrylic polymer. Alternatively, a rod of acrylic polymer surrounded by a flowable mixture comprising partially polymerized acrylic monomer and dye is subjected to polymerization conditions. |
