A new irrigating solution for intraocular surgery: TC Earle Solution

Electrolyte solutions--Plasma-lyte, TC Medium 199, TC Medium 199 plus additional bicarbonate, TC Earle Solution, and glutathione bicarbonate Ringer Solution--were evaluated for effectiveness in maintaining corneal thickness and endothelial viability. The TC Earle Solution was shown to be the most effective commercially available solution; little difference was demonstrated between TC Earle Solution and the experimental GBR Solution. Glucose and bicarbonate were found to be essential ingredients in the efficacy of the TC Earle Solution.
