New treatment "kills contact lens bacteria"

A relatively new technique may be able to improve the way in which bacteria on contact lenses is killed, according to a team of experts in the US.

Research carried out by specialist at National Jewish Health and the University of Texas Southwestern Medical Center claims that it may also be used in the treatment of bacterial infections associated with severe burns and cystic fibrosis.

In the study, published in the journal Investigative Ophthalmology and Visual Science, it is noted that cellular debris from immune cells fighting infection can provide the raw materials for biofilm - which makes bacteria in the eye harder to remove.

"The specialists used the enzyme DNAase together with negatively-charged poly aspartic acid to break down the chemical bonds of these elements that support the biofilm," the authors state.

They claim that this method may now help to provide the two in 10,000 contact lens wearers who suffer from the condition microbial keratitis with help.

Meanwhile, specialists at the Cole Eye Institute at Cleveland Clinic, Ohio, recently claimed that a new type of implant, which releases the drugdexamethasone, is a safe and effective treatment for certain types of uveitis, which is swelling and inflammation in the eye"s middle layer.
