Abstract: Compounds which enhance the efficiency of the corneal endothelial fluid pump thereby promoting normal corneal function and deturgescence of swollen corneas, and methods for the compounds' synthesis are described. In addition, surgical irrigating solutions which include one or more of the compounds are discussed along with methods for their use.

Abstract: A tissue irrigating solution useful for irrigating animal tissue, such as ocular tissue and neuro tissue, during surgery, contains sodium, potassium, magnesium calcium chloride, and bicarbonate ions as well as dextrose, glutathione, and gamma-amino butyric acid (GABA) or functional analogue(s) of GABA, or a mixture of GABA and such analogue(s) in proportions consistent with the osmotic stability and continued metabolism of the tissue cells. The irrigating solution is prepared by mixing a first basic solution which provides the bicarbonate and a second acidic solution which provides the calcium, magnesium, dextrose and glutathione. The first and second solutions may be stored as stable, sterile solutions for extended periods of time and mixed within 24 hours of use.
