Lighting plays a critical role in tissue visualization, surgical safety, and surgical speed. Learning to be a faster surgeon is less about trying to cut or suture more quickly than it is about being able to "see more quickly" and identifying critical structures so that the decision to cut or not can be made rapidly. In surgery, it can be difficult to discern between tissues such as veins, arteries, or nerves. Trainees are less skilled at identifying anatomy and patient-to-patient variability can be a challenge for all surgeons.



Commercially available surgical lighting (both ceiling mounted and headlamps) vary considerably in spectral response. Little is known about the optimal lighting characteristics other than brightness. Our aims are to determine the optimal spectral lighting characteristics for highlighting various tissue types and building a surgical LED array that provides optimal surgical lighting for specific procedures.
