[Calcium desorption from the cornea while using complex-forming substances].

: The time course of calcium desorption from the eye cornea and the efficacy of the use of complex-forming substances during desorption were examined. Experiments with labeled calcium showed an active absorption of the ions by the normal cornea thereby making it turbid. The removal of labeled calcium from an isolated eye and from corneal pieces while using a combination of complex-forming substances and diffusion facilitating-papain was accompanied by the lowering of tissue turbidity. Application of such combinations might eliminate, in some cases, the necessity of surgical operations on the cornea.
