Abstract
The pseudo-exfoliation (PE) material on the surface of extracted lenses [human] was not dissolved by a papain solution, while the underlying lens capsule was digested. This formed the basis of a method for isolating and collecting PE material. The anterior lens surface was swept with a cilium after the lens was suspended in a 5% papain solution for 0.5-1 h. The PE material was loosened in flakes which adhered to the tip of the cilium and could be collected as a lump. By light microscopy and scanning and transmission electron microscopy no contaminants could be seen, and no damage to the PE material was disclosed.
