            We uses a green and clean chemical vapor process to manufacture a new generation of intraocular lens. The materials use innovative polymer materials, which have high biocompatibility and stability, and have passed the United States Pharmacopoeia Class VI high biocompatibility. The polymer can quickly deposit a polymer film with reactive functional groups on the surface of the central liquid of the intraocular lens. The thickness can also be controlled at the nanometer level, and it provides the advantages of high refractive index and resistance to ultraviolet radiation. In addition, by adjusting the shape and curvature of the optical region of the liquid during the manufacturing process, the precise design of “customization” can be carried out according to cataract patients. In addition, combined with the scientific expertise of [Medical Equipment Surface Anti-adhesion Treatment Technology], the molecules with anti-adhesion properties (polyethylene glycol, PEG) attached to the surface of the intraocular lens can prevent human cells and impurities (calcium ions) from Attached to the surface of intraocular lens, while retaining the complete functionality of medical materials, mirror cleanliness and reducing the chance of secondary cataracts (calcium deposition). In addition, this technology can also determine the functional area (such as the size of the anti-adhesion area), so that a finished  intraocular lens has different characteristics. In addition to the surface of the intraocular lens, the temples of the intraocular lens are non-adhesive Surface, so it can be stably placed in the pouch. And this completely different function (anti-sticking of the mirror surface and non-sticking of the mirror foot) can be completed in one step.
          In summary, our team used this new material to create a new generation of intraocular lens, which have the ability to resist adhesion on the surface, and can also make them have the potential of versatility through the difference in chemical properties on the surface. It can be adapted to a variety of surfaces as required, and it can also be modified for the required characteristics of the surface. It is hoped that this innovative material and technology can lead the birth of a new generation of biomedical components in other biomedical material markets.
