Abstract: One aspect of the present invention relates to methods of treating corneal edema comprising contacting a cornea with an ophthalmic irrigating composition comprising histidine. In certain embodiments, the ophthalmic irrigating compositions contact the corneal endothelium. Another aspect of the present invention relates to ophthalmic irrigating compositions for treating corneal edema comprising histidine and optionally, calcium glycerophosphate and/or glutathione disulfide.

Abstract: One aspect of the present invention relates to stabilized irrigating compositions comprising sodium glycerophosphate and/or calcium glycerophosphate, and a bicarbonate salt. Another aspect of the present invention relates to methods of irrigating ocular tissues during a surgical procedure comprising bathing the intraocular tissues with an irrigating composition comprising sodium glycerophosphate and/or calcium glycerophosphate, and a bicarbonate salt.

Abstract: A solution packaging system and method of administering a solution are disclosed. One embodiment of the solution packaging system of the present invention comprises a gas-impermeable dual-chamber bag, having a first chamber and a second chamber separated by a frangible (releasable) seal, and an over-wrap member enclosing and containing the dual-chamber inner bag. The dual-chamber bag can be used to package two-part medicinal solutions containing bicarbonate, such as ophthalmic irrigation solutions. The first chamber can be filled with and contain a first part of such an irrigation solution, comprising, for example, a buffer such as bicarbonate. The second chamber can contain the second part of such a solution, comprising, for example, glutathione (GSSG), or other anti-oxidant, and dextrose, or other energy source. Both parts may contain other excipients.
