Abstract
New intraocular lenses (IOLs) and methods for producing IOLs. 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 or other exotic activation of the fixation member or primer coating of the fixation member. The silicone polymeric optic members employed in the present invention can be formed, for example, molded, without recesses to accommodate the fixation members. Such recesses can be formed and provided with a quantity of silicone polymeric material precursor composition after the optic members are produced. The 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.
