Abstract
The invention provides a composition and method for reducing structural defects in metastable systems. Structural defects represent spaces or vacancies in the structural order of the metastable system, which can be restored to the predefect order through the use of structure makers. These structure makers will then occupy the space or vacancy of the defect, restoring the order of the system. Lithium ions are used as a preferred structure maker to reduce the structural defects that lead to cataract in a human lens.
Claims4
A method of reducing eventual opacification in a human lens by reducing structural defects in a precursor mode, said method comprising:
- selecting an intact human lens having structural defects that are precursors to opacification therein;
- and
- exposing said human lens to an amount of a structure maker sufficient to reduce structural defects in said precursor modes, said structure maker selected from the group consisting of lithium salts, fluoride salts, calcium salts, and sources of hydroxide (OH.sup.-), said structure maker reducing said structural defects that eventuate in opacification in said lens.
