    摘要： New intraocular lenses (IOLs) and methods for producing IOLs are disclosed. The present methods include a combination of steps which increase the pull strength between the fixation member of the IOL and the optic of the IOL without requiring sophisticated high frequency corona discharge activation or plasma activation of the fixation member. The fixation members are doubly coated with primer components and silicone polymeric material precursor compositions before being secured to the optics. In addition, the optic members employed in the present invention can be formed, for example, molded, without recesses to accommodate the fixation members. Thus, such recesses can be formed and provided with a quantity of the above-noted precursor composition after the optic members are produced. The doubly coated fixation members are then placed in the recesses and secured to the optic members. The present methods are straight forward, easy to practice and are cost effective in producing high quality IOLs.

    摘要翻译： 公开了新的眼内透镜（IOL）和用于制造IOL的方法。 本方法包括增加IOL的固定构件和IOL的光学元件之间的拉伸强度的步骤的组合，而不需要复杂的高频电晕放电激活或固定构件的等离子体激活。 固定构件在固定到光学器件之前用底漆组分和硅氧烷聚合物材料前体组合物双重涂覆。 此外，本发明中使用的光学构件可以形成为例如模制而不具有凹部以容纳固定构件。 因此，在制造光学构件之后，可以形成这样的凹部并提供一定量的上述前体组合物。 然后将双重涂覆的固定构件放置在凹部中并固定到光学构件。 目前的方法是直观的，易于实践的，并且在生产高质量的IOL中具有成本效益。
