title: Deposition of substances within hydrophilic lenses.
abstract: One class of hydrophilic lens deposits appears as small, discreted spots under low magnification. Higher magnification of cross sections reveals partially crystalline structures which actually extend into the lens matrix. Histochemical stains indicate the presence of tear film components within these deposits.
