Abstract
An ophthalmic solution is provided for treatment of "dry eye", providing lubricating and cushioning effects for traumatized eyes, including trauma caused by the wearing of hard or gel-type contact lenses, and as a carrier for ophthalmic medicaments. The solution is an aqueous solution of polyethylene oxide, optionally polyethylene glycol, and other optional ingredients.
Claims13
An opthalmic solution consisting essentially of an aqueous solution of an ethylene oxide polymer, having a molecular weight of at least about 100,000, in an amount of from about 0.05 to 2.0 weight percent sufficient to provide a viscosity of from about 0 to 30,000 cps, from about 100 to about 5,000 weight percent, based on the ethylene oxide polymer, of a lower polyalkylene glycol, having a molecular weight from about 400 to about 6,000 and from .5 to 10 percent polyvinyl pyrrolidone based on the weight of the overall solution, said composition further including a therapeutically effective amount up to about 500 weight percent, based on the weight of the ethylene oxide polymer of an opthalmic medicament.
