ABSTRACT:
An improved method and assembly for attaching haptics to intraocular lenses. Method and assembly rely on shaping the attachment ends of plastic or metal haptics so that when inserted into openings in the lens, the haptics are firmly secured to the lens by constraining mechanical forces which arise from an added element, by molding or forming the constraint in situ using an external energy source to melt material of the haptic, or by bending a metal haptic to a holding shape. Melting of lens material is not required for this fastening method or assembly nor is wetting of haptic surfaces by material of the lens necessary.
