Abstract: A dissolvable medical device for placing on the outer exposed surface of the eye to deliver a drug to the eye comprising: a polymeric film has sufficient dimensions to substantially cover a cornea when applied to an eye, wherein the polymeric film comprising one or more mucoadhesive polymers. The polymeric film dissolves between 15 minutes to 120 minutes to release the mucoadhesive and the pharmaceutically active agents after applying the polymeric film to the eye. The dissolved polymeric film is not impeding visualization of ocular tissue while maintaining a protective film on outer surface of the eye.

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.
