Researchers develop method to deliver protein drugs though disposable contact lenses

Fort Lauderdale, Fla. — A new technique that delivers protein drugs via disposable contact lenses may eliminate the inefficiency and side effects of eye drops, according to the abstract of a poster presentation at the 2010 Annual Meeting of the Association for Research in Vision and Ophthalmology this week.

Researchers from the University of Western Ontario encapsulated water-soluable proteins that aid with wound healing and blood vessel regeneration into porous nanoparticles. The nanoparticles were then incorporated into disposable contact lenses, which then delivered the protein drugs over time.

According to the abstract, “It is expected that the nanoparticles-laden hydrogel lens materials are a new delivery system to deliver protein drugs, e.g. growth factors, to help blood vessel regeneration and potentiate greater angiogenesis.”

Abstract Name: Encapsulation and Releasing of Protein Drugs through Nanostructured Contact Lens
Presentation Start/End Time: Sunday, May 02, 2010, 8:30 AM -10:15 AM
Program No. 439
Location: Hall D, Broward County Convention Center
