Ophtalmologists often use 0,1 % Trypan-Blue (C.I. 23850, Synonyms: Direct
Blue 14, Niagara Blue 3B), an Azo-dye to stain the lens. In their opinion
this dye also makes the "capsule" of the lens somewhat more rigid and so the
capsulorhexis can be performed more easily. Any explanations for this
phaenomenon from the specialists (J.A. Kiernan!)? I've seen a couple of
those "capsules", without any light microscopical changes.
