ABSTRACT:
Apparatus for folding an intraocular lens about a blade-like inserter to reduce its width, and then rigidifying the folded lens in situ by chilling it until it remains folded on the inserter for insertion into the eye. The lens is positioned for folding on a seat in the folding apparatus, and the inserter blade is placed on the lens. A hinged arm folds one half of the lens over the blade. The lens is then chilled until rigid so that it remains folded around the blade, as by a cryogenic fluid circulated through the inserter. Also disclosed is a lens package having a removable carrier by which the lens can easily be removed from the package and positioned in the folding apparatus, without loss of sterility.
