Abstract: An artificial tear film over the surface of an eye having a first layer in direct contact with the ocular surface, an aqueous layer over the first layer, and a layer of a phospholipid over the aqueous layer. The first layer has polyvinyl alcohol, polyvinyl acetate, and polyvinyl pyrrolidone. The phospholipid is derived from Amisol® Clear. The artificial tear film is effective in significantly prolonging the tear break up time in patients with dry eye syndrome.

Abstract: A composition for treating dry eye includes eledoisin formulated in an ester form and a phospholipid formulated in a micellar form.

Abstract: A disinfectant or preservative composition particularly adapted for use in ophthalmic preparations such as contact lens disinfecting, cleaning, cushioning, wetting, soaking and reconditioning solutions and additionally in topical medications and tear substitutes, which uses a hydrophilic polymeric antimicrobial agent, namely poly[oxyethylene(dimethylimino) (ethylene dimethylimino)ethylene dichloride] with additional agents including EDTA and alkali salts thereof and a boric acid/borate buffer system.

Abstract: A synergistic combination of an aqueous solution of a partially hydrolyzed poly(vinyl acetate) and a fully hydrolyzed poly(vinyl acetate), i.e. poly(vinyl alcohol), exhibiting a low surface tension at the water-air interface, while forming a completely wettable absorbed layer over hydrophobic solids. The combination is used as part of an ophthalmic solution including a hydrophilic low viscosity polymer, poly(N-glucose) or poly(N-vinyl pyrrolidone) with higher than normal oncotic pressure in a physiologically compatible electrolytic solution base. The formulation is effective in treating the two major underlying causes of the dry eye syndrome; ocular surface disorder and tear film abnormalities resulting in tear film instability. It can also be effective as an aqueous vehicle for topically used ophthalmic drugs or nutrients.

Abstract: An ophthalmic solution for treating corneal edema concurrent with epithelial discontinuity, healing epithelial defects, and protecting against epithelial trauma containing electrolytes at only isotonic levels but containing hydrophilic macromolecules at such concentration that their collodial osmotic pressure is equal or greater than the imbibition pressure of corneal stroma.

Abstract: An ophthalmic composition for use in the human eye comprising an aqueous solution of fluorexon whose pH has been adjusted to between pH 5.4 and 6.2 to deliver maximum fluorescence and additionally containing sufficient buffer to maintain that pH even after instillation into the eye.
