Can continuous light cut surgical infections?

Challenge

Surgical site infections are a serious risk in operating rooms, and conventional disinfection can’t run safely while an OR is in use.

Approach

Human-safe UV222™ far-UVC in the C-section operating rooms, disinfecting continuously throughout live surgery.

Result

A 56% reduction in surgical site infections over six months — with no change to surgical workflow.

The Challenge

Infection risk when patients are most vulnerable

Operating rooms are among the most infection-sensitive spaces in any hospital.

Even with rigorous protocols, airborne and surface pathogens can persist during a procedure — and conventional disinfection happens between cases, not during them, leaving a gap precisely when patients are most exposed.

The Approach

Continuous far-UVC in the operating room

King Hamad University Hospital installed UV222™ far-UVC in its C-section operating rooms.

Human-safe 222 nm light runs continuously and autonomously during live surgical operations, adding a constant layer of air and surface disinfection without interrupting the surgical team. Results were measured across six months of real procedures.

UV222 far-UVC device — UV222 — human-safe 222 nm far-UVC, designed to run continuously in occupied rooms.

The Result

56% fewer surgical site infections

Across six months of real operations, far-UVC reduced surgical site infections by 56%.

It is a direct, measurable clinical outcome rather than a lab-only result — achieved with no additional steps for staff and no disruption to established theatre protocols.

“Continuous infection prevention — working safely alongside the surgical team, around the clock.”
