A new study which has pointed to a possible treatment for bacterial contact lens infections may also have implications for wider medicine, according to one expert.
Dr Danielle Robertson, first author and assistant professor of ophthalmology at the University of Texas Southwestern and first author of a new study into therapies for microbial keratitis, said that the research may also help other patients in the long run.
In the study, experts used the enzyme DNAase together with negatively charged poly aspartic acid to break down the chemical bonds supporting biofilm in the eye – a collection of bacteria suffered by two in 10,000 contact lens wearers.
They found that the treatment reduced biofilms on the contact lenses by 79.2 per cent of people, and Dr Robertson commented: "These are vey promising early results that point to potentially new methods for removing bacterial biofilms from contact lens surfaces, as well as the treatment of infections by pseudomonas associated with cystic fibrosis and severe burns."
A recent study carried out by specialists at the Cole Eye Institute at Cleveland Clinic, Ohio, 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.
