"IMPROVED VISCOELASTIC FLUID FOR OPHTHALMIC SURGERY AND METHOD OF USING SAME" ABSTRACT OF THE DISCLOSURE This invention relates to an improved viscoelaatic vitreous substitute for use in ophthalmic surgery which consists of a mixture of hydroxypropylmethyl cellulose and polyethylene oxide in selected concentrations not to exceed approximately 2% and 200 ppm, respectively, contained in a physiologic balanced salt solution. It also encompasses the novel method of protecting and lubricating the corneal tissues during surgery with uses of different concentrations of the same solution introduced simultaneously to protect the inner cornea while periodically irrigating the outer cornea, all without obscuring the surgeon's view of the site.
