    Abstract: Iris fixated intraocular lenses include an optic and at least one fixation member or haptic. The fixation member is joined to the optic and has a distal segment including a through-iris portion adapted to extend through an iris hole, and an anchor portion. The anchor portion has or is adapted to have an anchor structure positioned to be disposed proximate to a side of the iris so as to be a effective in fixating the intraocular lens to the iris. The anchor structure may be formed prior to inserting the intraocular lens in the eye or may be formed after the intraocular lens is inserted in the eye. Methods for inserting such intraocular lenses in the eye are also provided.

  • Patent number: 5423929
    Abstract: 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.
