Optifoam Basic is a non-adhesive hydrophilic foam dressing that is ideal for general wounds or tube site care. Optifoam Basic does not have a waterproof backing like the other Optifoam products. It absorbs exudate and provides a moist wound environment, making it ideal for light to moderate exuding wounds. Optifoam Basic Dressings are soft, conformable and cushioning which is good for bony prominences and site care. Latex Free and sterile.
