One major issue that surgeons face during closed body cavity surgery is fogging of the lens surfaces. The cloudy and opaque lens surface caused by water vapor present in closed body cavities forces the surgeon to repeatedly remove the endoscope, wipe it, and reinsert it back into the patient. This presents several risks such as increased surgery time, greater scarring, and an increased chance of infection. In order to address this issue, the development of the Thin Fluid Film Device (TFFD™) VitreOx™ aims to render the lens surface hydrophilic, whereas it is typically hydrophobic.
