Abstract
An apparatus and method for manufacturing intraocular lenses (IOLs) is disclosed. Two mold components (an outer mold component and an inner mold component) of different composition may be employed. The outer mold may be composed of a metal or other refractory material and may serve as the outer die into which a lens forming material can be introduced. The inner mold component may be composed of a softer or more compliant material and may be deployed within the outer mold component. The IOL may be formed by casting the lens-forming material into a shape defined by the space between the two mold components. In certain embodiments, the present disclosure may reduce or eliminate flash in IOLs, improve alignment of their optical surfaces, and/or reduce or eliminate the need for bonded regions.
