FDA grants approval of CL plasma treatment to B&L

Bausch & Lomb has received Food and Drug Administration approval to add a cold oxygen plasma treatment to its manufacturing process of gas permeable contact lenses, according to a company press release.

Plasma treatment is a process “that bombards the lens surface with ions in a vacuum,” the release said. The treatment “may reduce the lens hydration time by reducing the wetting angle,” which may improve patient comfort, the company said.
