【Abstract】 Silicone intraocular lens (IOLs) were modified with carbon and titanium respectively by the technique of ion beam combined with low temperature and low pressure plasma. Results of the determination of the surface properties showed that the resolution and the surface morphology of the modified IOLs were unaffected by modification processes. The modified IOLs increased the degree of absorption of ultraviolet rays more than unmodified IOLs. And the surfaces of modified IOLs became more hydrophilic. The chemical composition of unmodified and C-modified IOLs contained carbon, oxygen and silicon and Ti-modified IOLs were composed of carbon, oxygen, silicon and titanium. Therefore, the surface properties of the modified IOLs were improved.$$$$更多还原
