  • Production methods for intraocular lenses with high pull strength fixation members
    Patent number: 6251312
    Abstract: New methods for producing intraocular lenses (IOLs) include a combination of steps which provide outstanding pull strength between the fixation member of the IOL and the optic of the IOL without requiring the lens body region of the fixation member to have enlarged anchor structures. In one embodiment, the present methods include providing an optic member having a recess; providing a fixation member having a lens bonding region free of enlarged anchor structures; placing the lens bonding region into the recess; and thereafter doing at least one of reducing the size of the recess and increasing the cross-sectional area of the lens bonding region. The lens bonding region of the fixation member is thereby secured to the optic member.
