Contact lens coating to prevent keratitis

Researchers have developed a polymer coating for contact lenses envisaged to be promising for the prevention of contact lens-related keratitis.

Findings published in Biomacromolecules journal noted that microbial colonisation and biofilm formation was the leading cause of contact lens-related keratitis. It meant treatment of the condition was a challenge due to the need for prolonged therapeutic course and high doses of antimicrobial agents, especially for biofilm eradication.

The development of strategies to prepare non-fouling contact lens surfaces was a more practical way to ensure users' safety and relieve the excessive public healthcare burden, the researchers said.
