I specialise in dealing with fungal eye infections.
At present, treatment involves giving eye drops every hour for at least two weeks.
I wanted to improve this process, by designing a system capable of releasing anti-fungal drugs onto the eye over an extended period.
Contact lenses are perfect for this,
as their hydrogel structure has the ability to uptake and release drugs,
and their placement on the eye ensures the drug gets released directly to the cornea.
In order to make a contact lens provide drugs over a sustained period,
I've modified the lens.
I've also used nanoparticles for packaging the drugs.
So, I've managed to create a system capable of delivering an anti-fungal drug called Nanomycin for up to four hours.
I now hope to increase this, and use this system with other drugs.
