Abstract: An improved method for making a monolithic intraocular lens and haptic structure. The invention comprises the process of assembling easily available materials into a composite structure having an inner core of optically transparent lens material with broad or selectively tailored wavelength transmission characteristics surrounded by a jacket of colored haptic material having the same composition and mechanical properties as the lens material. The composite structure is then bonded into a monolithic rod with a bonding process wherein the bonding material in the interface between the lens core and the jacket also has the composition and mechanical properties of the lens material. After bonding, the composite structure is sliced into blanks from which lenses with colored haptics can be fabricated.

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.
