  • Publication number: 20210169781
    Abstract: Polymeric eye inserts are provided that may be dissolvable when placed in the cul-de-sac of the eye. These inserts may contain one or more mucoadhesive polymers polymers, a biodegradable polymer as well as softener/plasticizer so that, when inserted into the eye, they may absorb tears, and dissolve and slowly release lubricant into the tear film to lubricate and protect the ocular surface for an extended duration of time. The biodegradable polymer containing eye insert may increase dissolution time on the ocular surface for longer lasting relief, may reduce dosing frequency and patient burden typically associated with topical drop usage. These polymeric eye inserts also may include one or more pharmaceutically active agents.

  • Patent number: 10584307
    Abstract: The use of poly(oxyethylene)-poly(oxybutylene) block copolymers in pharmaceutical compositions useful for modifying the surfaces of contact lenses and other medical devices is disclosed. The present invention is based in-part on a discovery that this class of compounds is particularly efficient in wetting hydrophobic surfaces, such as the surfaces of silicone hydrogel contact lenses and other types of ophthalmic lenses. Such compounds are also useful for cleaning purposes. The use of the compounds as surfactants in various types of compositions for treating contact lenses therefore represents a preferred embodiment of the present invention.
