Abstract: A syringe system for dispensing or injecting one or more fluids is provided. The syringe system includes a hollow body that retains cartridge(s) and/or syringe(s) each containing a fluid, such as an injectable fluid e.g., a catalyst in one cartridge and a polymer in the other. Upon use for dispensing two fluids, the syringe system mixes the two fluids immediately prior to or concurrently with the dispensing or injecting of the fluids. The syringe system can also be configured to independently dispense a single fluid or immediately dispense multiple fluids sequentially.

Abstract: A corneal storage solution which maintains cell density and cell viability of corneas stored in vitro for a period of greater than four days up to about two weeks is provided. The solution contains a buffered, balanced, nutrient and electrolyte aqueous solution, at least one colloidal osmotic agent, a phenolic antioxidant compound, a non-lactate-generating substrate, a thiol-containing compound, insulin, and at least one antibiotic. A method for in vitro storage and preservation of the viability of human corneal endothelial cells for subsequent use includes the steps of removing a cornea from an eye globe and placing the cornea in the above corneal storage solution.
