Abstract: An improved method for rapid disinfection of contact lenses in a convenient and reliable manner is disclosed in which a series of oxidation-reduction reactions are employed. Specifically, dichloroisocyanurate and potassium iodide react to form iodine species for disinfecting the contact lens. An amount of ascorbate is then added to neutralize the iodine species.

Abstract: Anti-inflammatory compounds, a method of treating inflamed ocular tissue and compositions of these compounds are described. The compounds are derivatives and analogues of known steroid compounds (e.g., dexamethasone) and are advantageously characterized in that they do not cause any significant increase in intraocular pressure during chronic use.
Abstract: Pharmaceutical compositions useful in the treatment of ophthalmic inflammation and methods of treating ophthalmic inflammation with those compositions are disclosed. The compositions contain a combination of a glucocorticoid and an angiostatic steroid. The angiostatic steroid substantially prevents any significant increases in intraocular pressure which might otherwise be experienced by the patient as a side effect of the glucocorticoid component of the compositions. The therapeutic interaction of the two components therefore allows the potent anti-inflammatory properties of the glucocorticoids to be utilized without fear of elevating intraocular pressure.
Abstract: Topical ophthalmic compositions of carrageenans which are administrable as a drop but which become more viscous or gel upon instillation in the eye are disclosed. Methods for use of the compositions as topical ophthalmic vehicles for pharmaceutically active agents, and alone as lubricants or tear supplements, are also disclosed.

Abstract: Aqueous ophthalmic compositions containing water-soluble borate-polyol complexes are useful in aqueous ophthalmic compositions containing polyvinyl alcohol. These compositions provide the benefits of a borate buffering system, such as enhanced antimicrobial activity, without the problems associated with the use of borate and pol, such as formation of borate-polyvinyl alcohol complexes which are water-insoluble.
Abstract: Topical ophthalmic compositions comprising certain thiadiazoles are useful in the treatment of glaucoma and ocular hypertension. The thiadiazoles are slightly less potent than timolol; however, they have greatly reduced systemic side effects as compared to timolol.
Abstract: Novel polymeric antimicrobials having spacer moieties between amine and/or ammonium moieties have good antifungal activity. These compounds are useful in pharmaceutical and cosmetic compositions as preservatives and in contact lens care compositions as preservatives and/or disinfectants.
Abstract: Certain sulfamoyl-substituted phenethylamine derivatives have been found to be useful in reversing or inhibiting drug-induced mydriasis. This application is especially useful in the area of diagnostics for eye examinations.

Abstract: Ophthalmic pharmaceutical compositions useful in controlling elevated intraocular pressure associated with glaucoma and ocular hypertension are described. The compositions comprise a combination of a beta-blocker to reduce the production of aqueous humor and carbachol to enhance the outflow of aqueous humor. A method of controlling elevated intraocular pressure with those compositions is also described.
Abstract: Disclosed is the use of combinations of the prostaglandins PGF.sub.2.alpha. and PGE.sub.2 and their respective derivatives, and pharmaceutically accceptable salts and esters thereof in the treatment of glaucoma and ocular hypertension. Also disclosed are ophthalmic, pharmaceutical compositions comprising said combinations.
Abstract: A method for polishing articles manufactured from silicone rubber or silicone elastomers is disclosed. This method includes tumble-polishing in a receptacle charged with polishing objects, an alcohol solvent, and silicone articles for a period of time and at a rotation speed sufficient to remove surface irregularities and produce the desired finish and/or improve the optical transparency of the silicone articles. This method is particularly useful in the polishing of biomedical articles such as intraocular or soft contact lenses, tips of cannulae, and articles such as O-rings for precision mechanical devices.
