A way of eradicating a bacterial infection associated with contact lenses is an important development in the field, one expert has noted.
Dr Jerry Nick, associate professor of medicine at National Jewish Health at University of Texas Southwestern Medical Center, said a study conducted by the facility, showing how to eradicate microbial keratitis, may prevent many people from experiencing a painful and uncomfortable condition.
He noted that infections caused by the bacteria Pseudomonas aeruginosa can cause severe scarring and vision loss when it spreads to the cornea.
However, the expert explained: "By breaking apart a molecular scaffolding that encases the organisms and makes them more difficult to eradicate, we were able to significantly reduce bacterial infection of the cornea."
Meanwhile, recent studies carried out by engineering researchers at Rensselaer Polytechnic Institute in New York found that liquid piston technology developed by experts in the US may lead to the creation of adaptive contact lenses which can boost drug delivery.
