  • Patent number: 8733937
    Abstract: Methods and devices measure eye blinks and tear film lipid and aqueous layer thickness before and following ophthalmic formula application onto the ocular surface, especially wherein the ophthalmic formula is an artificial tear. The methods and devices are suitable for dry eye diagnosis. The methods and devices are suitable for use to evaluate ophthalmic formula effects on the tear film and to use such information to diagnose ophthalmic formula treatment of ocular disease conditions such as dry eye in the absence of contact lens wear or post-surgical eye drop treatment and diagnosis. The methods and devices are also suitable for use in the optimization of ophthalmic drug dosage forms and sustained drug release.

  • Publication number: 20040185068
    Abstract: Preparation of self-emulsifying compositions which are prepared without mechanical homogenization is described. These self-emulsifying compositions are prepared using one or two surfactants. This provides the advantage of a low weight ratio of emulsifying component to oil component and fewer chemical toxicity concerns, resulting in comfort and safety advantages over emulsions employing more than two emulsifiers. Consequently, the self-emulsifying compositions described are ideally suited for ophthalmic applications including administration of therapeutics to the eye. Self-emulsifying compositions prepared by the disclosed method are described.
