APPARATUS AND METHOD OF MANUFACTURE OF INTRAOCULAR LENSES

摘要

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.

主权项

1. An apparatus for manufacturing an intraocular lens, comprising
an outer mold constructed of a first material, the outer mold comprising a cavity; an inner mold constructed of a second material, the second material being more compressible than the second material, the inner mold configured to be inserted into the cavity of the outer mold such that a space between the inner mold and the outer mold defines the shape of the intraocular lens; one or more ports in the outer mold, the one or more ports facilitating introduction of a lens-forming material into the space between the inner mold and the outer mold.
